Episode one, launch and test. 00:42 We launched Willow at Gravelly Beach. 00:47 On the Tamar river in Northern Tasmania. 01:14 I'll be testing out the new rig and the tarpaulin sail I made for her. 01:23 And seeing if the bilge keels I made will work. 01:29 later in the video I will use GPS to measure how effective they are. 01:45 The tarpaulin sail is just a temporary measure to check the balance and performance of the boat. 01:54 I'll keep using it though, to see how long it lasts. 01:57 and post updates in the 'description' part of my sail making video. 02:07 *Sorry for the low resolution in this part. 02:10 I couldn't get any closer to shore. 05:39 "Hang on to that" 05:44 "you're sailing" 05:44 My son's first time sailing. 05:45 "yippee!" 05:46 " try to head for the right hand side of that row of white buildings." 05:59 He headed out on a very long tack in 20km of very consistant wind. 05:59 The boat stayed on course, with slight weather helm. 06:04 The sail is only 60 sq ft and easy to handle. 06.09 missed tying off an eylet. 06:15 "Good stuff right?!" 06:16 "yeah." 06:29 Coming back downwind. 06:52 "It's fun sailing with that little bit of swell. It's very easy to steer down wind...yeah It's staying on course so nicely. I'm barely having to touch the tiller." 07:11 " The tide is coming up, we're actually travelling with the tide but its still going very slow. What time is it?" " Three forty one" " Ah, so the tide has been coming in for a bit less than an hour." 07:31 When we were at the bottom of the tide and the water was still, we conducted a test to see how well Willow sails to windward. 07:40 We had already sailed her for a while at this stage and I was pleased with the way she handled and pointed. 07:47 ...but the scientific part of my brain wanted some data! 07:52 As we sailed upwind, we used the Wavve Boating app to record our course. 08:01 This gave us an accurate record of our course over ground. COG 08:07 Then I was able to measure the tacking angles afterwards, using another app. 08:22 Here is an animation showing us tacking upwind, synchronised with the route that we recorded at the time. 08:29 It was in very light 6-10km/h wind, so l've speed parts up and skipped some parts. 09:04 The first tack was 43.5°. 09:12 I'm trying to head for that little white house on the shore. 09:15 There! 09:53 45° that time. 10:00 The wind began to fade as we went on. 10:24 "You've got to give it time to come about, you can't just tack and pull in the sail quickly." 10:26 This tack and the next one were 50° each, so not as good as the first two. 10:34 "But see, we were heading for that white house before." 10.41 It's OK I think. Tacking through the wind 100° at worst and 87° at best, with leeway taken into account.. 10:50 ...especally-in these light winds. I can tell that she points higher in a little more wind. 10:59 There's that white house now. 11:18 I haven't had any problems turning her through the wind, even in the lightest conditions. 11:26 Which is way better than I expected with such a shallow draft. 11:34 So there we have it! That's how she sails to windward in light air, with just bilge keels and a tarpaulin lugsail. 11:42 let's go back to that downwind sail. 11:52"There's a bit of a breeze." 11:58 "She must be going fast now" 12:03 "8km/h..9km/h..and back to 8." 12:11 "Nine is the maximum." 12:14 " Nine is the maximum...in this wind anyway. 12:26 "That's five knots." 12:30 "Is that about what you expect?" 12:31 "It's about the hull speed of the boat, so its going to take a lot more wind to push it any faster. And it's about the speed that it goes along with the outboard motor...so that is respectable." 12:55 "Can you row and sail at the same time?" "Yeah, do you want to do it?" 13:01 "I can't lean back much, I'm on the edge of my seat." 13:03 "Put your feet out, and sideways a bit..that's better, that's more like it!." 13:16 "hehe" 13:17 "we're not actually going any quicker." 13:17 " you're actually probably slowing us down because you are dragging..." 13:21 "I'm not dragging" 13:22 "Get that oar vertical." 13:31 "There we go!" 13:41 ☠️ Time for these pirates to pack up! 13:52 Ok, we might work on our sail dropping skills a little bit. 14:11 Next time I will take her on a cruise. 14:26 Until then. 🫡
Thankyou, I wasn't sure if they would work but they do in this case. Have fun with that Scow! Cast iron not ideal? Is it because it's brittle or something else?
Beautiful, classic lapsterrack dinghy! Excellent results sailing upwind with a lugger sail with a tarpaulin and bilge keels! Cool video! Greetings from Poland (also from lugger sails) 😀
Greetings Robert! ( I think you are the fourth Robert to comment. My son's name is also Robert and my name spelt backwards is Rovert. Perhaps I should change my channel name to Sailing Roberts. Lol) Thankyou my lugsail friend for your comment. 😊
Wow! This is awesome Trev. She looks like she handles amazingly. Great camera work by the 1st mate there too. I just bumped into your channel yesterday and watched Willows transformation. Great job. Looking forward to more action.
That is amazing, she looks great on the river. Wouldn't be surprised if the only thing that bothers the sail is the UV, I wonder if another option for your sails could be the painting drop sheets that Aldi has every so often, I made a hammock out of one a while back and its pretty secure, but I often thought of using it for a sail. ...mind you that requires building a boat first ....
Thank you, Mark.That's right, I will have to sail on low UV days to get the most out of it. That hammock sounds cool. How about an Aldi drop sheet sailing canvas on frame canoe? 😉😄
Very apropos of my current build project: a 16-foot hard-chine micro cruiser I designed myself. I pondered long over keel arrangement and have decided to go with long, shallow, outward canted bilge keels just like yours. It is a great comfort to see them work so well. My sail will start off made from a tarp, as I'm experimenting with a junk (Chinese lug) sail. That's a nice old boat you have there. Looks like great fun. I'll be putting mine in the water at Goolwa, South Australia. Cheers.
Hi Robert. I think it's a combination of the 6 inch keels and the central keel being about 8 inches at the stern that makes it all work. Probably the safest way to assure it will sail well is to design the rig after you put the boat in the water. That way you can push your boat sideways in the water and work out exactly where the center of lateral resistance is and then design your sail so the center of effort is forward of that. I didn't do it that way. I figured it on paper and used a bunch of assumptions and comparisons to other designs, resulting in a lot of sleepless nights and worries till it was launched haha.. Anyway best of luck with yours and rest assured they do work well. Thanks for your comment!
@@TrevC-co6xk Thanks for the reply, Trevor. That's good advice. I've been re-consulting my library of boat designing books, including the "Bible" of junk rigs, and done all my calculations - knowing that the dynamic reality can be different to the static theory. My mast position fore-aft will be fixed as it will step in a tabernacle (for going under bridges, etc.). With any lug rig, one has some small adjustment fore-and-aft, but I've also designed in a step on the stern transom for a small mizzen in case of excessive lee helm. In addition, by making a tarp sail (cheap) I can test it first without risking a bunch of money, and make a better quality sail based on the trails with the tarp. As for keels, I will build them long enough to trim off either end to adjust the CLR if necessary, and there will be a skeg aft equal in draft to the keels, also to give stable drying out. Much fun ahead! All the best.
@TrevC-co6xk it's been a long time since I want to build a sailboat, but kinda stuck in choosing what design, too much to choose only one, feel like I have to build every single design... aarrggh, I hate my mind
I know it's a huge dilemma! I've owned three different types of boats ( 24ft keel, 18ft trailer sailer and this one). They're all so different, but they take you to the same good place.
Very impressive performance! If you can get the gps data it's possible to wrangle it into a spreadsheet and produce a polar chart, interesting for viewing speed vs angel to the wind. It looks to me like you could do with either a vang, or a traveller on the back to keep the leech tight using mainsheet tension, to get a little more out of her still. Love the standing lug!
Thanks Thomas, yes it would be intriguing and useful to know that kind of detail. I would need something better than the app that I was using as it only measures speed in whole units ( as does my handheld Garmin GPS). I can easily attach a boom vang and you are right. I should try that.
@@TrevC-co6xk I was thinking the same, but possibly all you need to do is move the attachment point for your downhaul a couple of inches back on the boom. Then it becomes a "Vanghaul" (see articles by Michael Storer on his web site).
Thanks Chris. I made provision for an attachment point for a vang about a foot back on the jaws when making them. I can make a very simple vang that loops around the boom, goes down to eye plate at the base of the mast then back through the loop to a clam cleat. It all kind of got forgotten in the exitement .I will try it next time i go out.
@@TrevC-co6xk If you combine the downhaul and the vang into one, ideally the attachment point should not be more than about 5 to 6 inches back from the mast. You also need to lead the control line to the cockpit, as the tension should (also ideally) be adjustable according to conditions and point of sail.
Have you tried swamping her to test your flotation? How about righting her after a capsize? I'm sure you're testing all of this. Looking very good mate!
That's definitely something I want to try at some stage, especially before I venture out and do some of the little coastal hops that I'm planning in the back of my mind. I know the perfect place to give it a go. Will be interesting to see if i can get enough leverage without a centreboard. I suppose I would need to attach a weight to the transom to simulate having my outboard there as well. All in good time. I will try some river cruising and take things steady till then. :) Thanks again ! !
@@TrevC-co6xk When I used to sail my little Coronado 15 solo it was a common occurrence to capsize. I'd have to right her by myself. It's good practice. I'm sure there's a saying that goes something like "there's 2 types of dingy sailors" those that have capsized, and those that are going to". Better to be comfortable doing it and getting used to it.
@@MrWhynotnow A bit like paddling kayaks, you better work out how your going to get back in when not if you arse out. If it's a two man achieving the eskimo roll is not really always an option.
@@ranter7100 Yeah, I've been a whitewater kayaker for years. Knowing how to get back up in any conditions isn't just a convenience, but can be a matter of survival. You have to practice until it's muscle memory. Same with sailing a dinghy. You don't want to learn far offshore in a gale.
I bought them. They are not specified for marine use so I am hesitant to recommended the specific product and brand. Where I live there are no specific regulations on buoyancy and I've just chosen something that I have tested and consider safe and have taken steps to protect them.
Very sturdy and beautiful boat. You guys obviously had a good time on the water. Your gaffe attachment and mast/sail overlap is confusing to me. Maybe you will be able to go closer upwind if you adjust that Cheers
Thanks and yes we did have a very nice time. The rig is a standing lugsail, a type of old world sail used on working boats. It's meant to overlap like that but you are right they are not the most efficient sail to windward. It's redeeming features are that it is powerful for its size, easy to set and handle, and the whole thing stores in the boat.
Wire on boat is probably to stop otters and other sea life from coming aboard. Lovely job on your boat I sail a Gartsode 130 12' clinker dinghy with a standing lug. For fun I added a removable sprit and often fly a jib. Are you playing the guitar? Sounds Nick Drake-esque
Haha yeah that's right, my son thought it looked like the top of a prison wall but it's security against seals probably. Yep, that's me having a dabble on the guitar. I like your jib idea.
Thankyou! She's a 12ft plywood carvel built by Purden and Featherstone boat builders in Hobart Tas , Australia.1940s. The deck, keels, rudder and sailing rig are my addition.
I have a few (I hope constructive) comments. The second sheet block, halfway along the boom is in the wrong place unless you also have a block on the centre thwart. But that would obstruct the crew. The keels have very little to do with tacking angle. Measure the leeway; that’s far more important. GNSS is the wrong tool for measuring tacking angle. It measures COG, which will be affected by the tide even at apparently slack water. Use a compass.
I agree it's not a perfect test because there could still be some movement in the water. It satisfies my basic curiosity as to the ability of this boat to tack upwind. I think using a compass only though will not give an accurate result as it can only show the direction you are pointing on each tack and not take into account how far you are sliding sideways. GPS is giving an accurate overall picture..I will try it on a lake at some stage.

00:20 Sailing "WILLOW". Episode one, launch and test.
00:42 We launched Willow at Gravelly Beach.
00:47 On the Tamar river in Northern Tasmania.
01:14 I'll be testing out the new rig and the tarpaulin sail I made for her.
01:23 And seeing if the bilge keels I made will work.
01:29 later in the video I will use GPS to
measure how effective they are.
01:45 The tarpaulin sail is just a temporary measure to check the balance and performance of the boat.
01:54 I'll keep using it though, to see how long it lasts.
01:57 and post updates in the 'description' part of my sail making video.
02:07 *Sorry for the low resolution in this part.
02:10 I couldn't get any closer to shore.
05:39 "Hang on to that"
05:44 "you're sailing"
05:44 My son's first time sailing.
05:45 "yippee!"
05:46 " try to head for the right hand side of that row of white buildings."
05:59 He headed out on a very long tack in 20km of very consistant wind.
05:59 The boat stayed on course, with slight weather helm.
06:04 The sail is only 60 sq ft and easy to handle.
06.09 missed tying off an eylet.
06:15 "Good stuff right?!"
06:16 "yeah."
06:29 Coming back downwind.
06:52 "It's fun sailing with that little bit of swell. It's very easy to steer down wind...yeah It's staying on course so nicely. I'm barely having to touch the tiller."
07:11 " The tide is coming up, we're actually travelling with the tide but its still going very slow. What time is it?"
" Three forty one"
" Ah, so the tide has been coming in for a bit less than an hour."
07:31 When we were at the bottom of the tide and the water was still, we conducted a test to see how well Willow sails to windward.
07:40 We had already sailed her for a while
at this stage and I was pleased with
the way she handled and pointed.
07:47 ...but the scientific part of my brain wanted some data!
07:52 As we sailed upwind, we used the
Wavve Boating app to record our course.
08:01 This gave us an accurate record of
our course over ground. COG
08:07 Then I was able to measure the tacking angles afterwards, using another app.
08:22 Here is an animation showing us tacking upwind, synchronised with the route that we recorded at the time.
08:29 It was in very light 6-10km/h wind, so l've speed parts up and skipped some parts.
09:04 The first tack was 43.5°.
09:12 I'm trying to head for that little
white house on the shore.
09:15 There!
09:53 45° that time.
10:00 The wind began to fade as we went on.
10:24 "You've got to give it time to come about, you can't just tack and pull in the sail quickly."
10:26 This tack and the next one were 50° each, so not as good as the first two.
10:34 "But see, we were heading for that white house before."
10.41 It's OK I think. Tacking through
the wind 100° at worst and 87° at best,
with leeway taken into account..
10:50 ...especally-in these light winds.
I can tell that she points higher in a little more wind.
10:59 There's that white house now.
11:18 I haven't had any problems turning her through the wind, even in the lightest conditions.
11:26 Which is way better than I expected
with such a shallow draft.
11:34 So there we have it! That's how she sails to windward in light air, with just bilge keels and a tarpaulin lugsail.
11:42 let's go back to that downwind sail.
11:52"There's a bit of a breeze."
11:58 "She must be going fast now"
12:03 "8km/h..9km/h..and back to 8."
12:11 "Nine is the maximum."
12:14 " Nine is the maximum...in this wind anyway.
12:26 "That's five knots."
12:30 "Is that about what you expect?"
12:31 "It's about the hull speed of the boat, so its going to take a lot more wind to push it any faster. And it's about the speed that it goes along with the outboard motor...so that is respectable."
12:55 "Can you row and sail at the same time?" "Yeah, do you want to do it?"
13:01 "I can't lean back much, I'm on the edge of my seat."
13:03 "Put your feet out, and sideways a bit..that's better, that's more like it!."
13:16 "hehe"
13:17 "we're not actually going any quicker."
13:17 " you're actually probably slowing us down because you are dragging..."
13:21 "I'm not dragging"
13:22 "Get that oar vertical."
13:31 "There we go!"
13:41 ☠️ Time for these pirates to pack up!
13:52 Ok, we might work on our sail dropping skills a little bit.
14:11 Next time I will take her on a cruise.
14:26 Until then. 🫡
Great little boat and I love the "make do" attitude. Most impressive!
It's my inner Huckleberry finn maybe, haha. Thanks for your comment!
For some reason I can't give you a thumbs up - so here it is. Love your boat and polytarp sail.
😊 Thanks for that!
Oh wow Trevor this fantastic I love your channel ❤❤
Thanks so much Angie! 😻
Well, that was none too shabby. Impressed with you sailmaking. It set right pretty. Cheers
Thanks Garrick 👍
Beautiful boat build!
Thanks 😊
What a great idea to add bilge keels to a dinghy! I've recently got an old Keyhaven Scow with a cast iron centreboard, which isn't ideal
Thankyou, I wasn't sure if they would work but they do in this case.
Have fun with that Scow!
Cast iron not ideal? Is it because it's brittle or something else?
really touching !
Thanks, yes treasured time.
Beautiful the skills he'll learn especially in todays world are priceless. Lovely day on the water.
Thanks, there's nothing like it.

She's on a nice little boil! Looks like a little Catboat. Did you make or buy the air bladders, if the latter, who makes them?
I bought them. They are not specified for marine use so I am hesitant to recommended the specific product and brand. Where I live there are no specific regulations on buoyancy and I've just chosen something that I have tested and consider safe and have taken steps to protect them.
Very sturdy and beautiful boat. You guys obviously had a good time on the water. Your gaffe attachment and mast/sail overlap is confusing to me. Maybe you will be able to go closer upwind if you adjust that

Thanks, no standard.
lovely looking dinghy, what design is she?
Thankyou! She's a 12ft plywood carvel built by Purden and Featherstone boat builders in Hobart Tas , Australia.1940s. The deck, keels, rudder and sailing rig are my addition.
Fantastic boat!! May I ask what is is? Looks like a 1915 clinker
Thankyou! The details about it are in this vid, th-cam.com/video/CN17GwvU5S0/w-d-xo.htmlfeature=shared
It's 1940s and a plywood carvel.
Beau travail.cette voile est plutôt bien adapté à votre dériveur. de quelle matière est la voile . Merci
Merci ! The sail is just made out of medium weight polyethylene tarp..the cheap kind from a hardware store. Thanks for watching!
I have a few (I hope constructive) comments.
The second sheet block, halfway along the boom is in the wrong place unless you also have a block on the centre thwart.
But that would obstruct the crew.
The keels have very little to do with tacking angle.
Measure the leeway; that’s far more important.
GNSS is the wrong tool for measuring tacking angle. It measures COG, which will be affected by the tide even at apparently slack water.
Use a compass.
I agree it's not a perfect test because there could still be some movement in the water. It satisfies my basic curiosity as to the ability of this boat to tack upwind. I think using a compass only though will not give an accurate result as it can only show the direction you are pointing on each tack and not take into account how far you are sliding sideways. GPS is giving an accurate overall picture..I will try it on a lake at some stage.
What kid wouldn't benefit from a ride on this boat?
This big kid certainly does :)
Какая плотность брезента? Спасибо.
It is 100g/m2. It is adequate but if you can get 150g it would be perfect.
Спасибо. Имею 200 г/м2, буду пробывать….
That will work very well!
@@TrevC-co6xkспасибо! А какая у вас площадь паруса, на этой лодке? ( S m2)
5.6 m2. It is a bit small for this size boat. I find it comfortable and relaxing though..especially when it gets windy. No need to reef.
