Shearing action on the fins cleaned the barnacles off very well. Just their footprint left. Better than a scraper. Besides I didn't have a scraper with me.
As a boat owner just a quick look at all that growth on the O.B leg (suspect that the bottom of the dingy would need attention too) just a couple of hours with a high-pressure hose, brush and scraper to removing that and give improved performance.
When you install one of these, the correct trim becomes more important. We have a single piece style with a more aggressive shape on a 15Hp Mercury and it makes a world of difference. Your friend might want to consider raising his motor after it's cleaned to combat the excessive growth. Thanks for the upload.
I'm glad you make these videos. You remind me of my dad you remind me of my dad very intelligent man. You just explained it so I new what to look for and do thanks. Good sailing
I got the same tail for my 16' V Alumicraft w/ 25hp Johnson 2 Stroke. It'll do 32mph now, the hole shot is super fast & most importantly that front end lays down & I can control the boat much better. Before I could get 2 hours loaded down on 6gal of fuel, I'm getting almost 3hrs now. Boy she flies now! They claim 30% more fuel & better stability & I believe it. I ran one on my new 18' Years ago & it made a huge difference also. Every boat I get, I install that Tail
Yes that's just the kind of setup that this helps best. I really like the alumacraft. We just switched from a 50 year old alumacraft to a new lund 12. Wish I had bought another alumacraft in many ways.
I run a 12 fiberglass hull w/15hp merc 4 stroke... weight is everything more so the placement... If a ran a extension handle on my tiller it fixed my planning issue. And ran 29mph gps. Then I ordered these exact fins, and yes it jumps on a plane but I lost 3 mph!. Personally I'd rather move my seat 6" forward than loose 3mph. But I am the guy that chases every pony and mph
Great straight forward video, right to the point. These planning fins are very good on all sorts of boats and motors. They work equally well on sterndrives for smaller runabouts. Thanks for sharing
Nice add on.. Just fitted a different design on my mariner 6hp. Only thing I want to say is that you can improve the performance. Move the fins till they line up the start of prop. That is the correct position. They will sit farther out the back but that will give yet more leverage to keep the front down.
With the 6hp and 2 people onboard, did the fins make any difference in planing speed? My suzuki 6hp is just on the limits, it is impossible to plane with 2 people unless two people weigh less than 150kg together.
Lower prop pitch helps your hole shot gets on plane faster. May try four blade prop. Will reduce speed a bit but also helps achieve faster plane and also keeps on plane at slower speeds. The fun will cause more drag and reduce overall speed.
I've done both. You are mostly right. Fin doesn't seem to cause more noticable "net" drag on boats that need it. Makes handling better and is cheaper then a lower pitched prop.
First clean all the lower unit. That has a lot to do with the performance. Second is get a one piece Hydrofoil they work much better. Stingray makes a really good one for a engine this size
@@Clarks-Adventure Yeah we just upgraded our dinghy & outboard and can't wait to get on a stable plane. We are still in the Chesapeake now but we're getting reading to make our way back down! Are you guys heading back to Bahamas soon?
I think we might have had enough of the unpredictable management of the Bahamas. They are not dealing with the pandemic well. It all depends on when vaccines become available. We might stay here till we go to Panama. -C
@@Clarks-Adventure I don't blame you. We've been back and forth about making the trip all season. Finally decided to head south for weather, we will see how Bahamas is doing when we get down to Fl.
Cool content buddy! I'm going to have to agree with you, hydrofoils are a must with any dinghy regardless of size due to the construction of their hull or transom. Soft inflatables and rigid inflatables just do not have the same vessel integrity that a full on fiberglass boat does. Happy boating! You have a new subscriber. Very cool channel.
Had some serious festoons of kelp around a 9.9 Yamaha some weeks ago. Didn’t cut of even on high revs, neither on reverse… Had to lift an reach by hand all the way back in gale force and low tide. I like these fins and probably going to bring a pair, but there are moments where you can get entangled I’m sure. Not a big deal in tropical waters, but in higher latitudes you have to think through every situation that might appear.
Yeah that sounds like a time when it would at least be harder to clear the prop with one installed. I sailed out of kelp when I left the waters of California. That stuff can be strong! If your boat doesn't need this help there would be no reason to install one. When I used boats I built and designed myself I didn't use one. No need as the hull solved this issue with it's form.
Hydrofoils lift the boat out of the water. But I bet someone named their competition "hydrofoil". If so stupid name , but I expect it would work similarly.
Sure. It depends more on the size of the outboard. They make bigger fins for bigger motors. But you could put these very fins on most any motor to good effect. Bigger fin more lift.
No worry of them falling out. I think the instructions say nuts up because the bottom is smoother with the machine screw heads. Less drag? That is just a guess. Anyone else have an idea? But I'm certain it will work just fine either way.
Less drag from the mounting hardware is the idea here. You want the least amount of hardware protrusion on the bottom of the anti ventilation plate to avoid drag as you move through the water.
Ty for sharing your tech-tips more often ..... why do I have the impression, that part of this tech-vid-spree is avoiding to do a sing & dance video with Emily ? Sail safe
@@Clarks-Adventure it does plane quick but it doesnt go very fast i Thit a lot of research and with a hydrofoil it should go faster but im not sure of i should buy a hydrofoil
I'm sure it improved the ride, however. Before you put on the fins, you were further back in the boat. It would have been more impressive if you were sitting in the same position/place for the comparison.
No one is lying to you here. I'm sorry you have trust issues. Please look at the rest of my body of work and decide if I'm trying to mislead you. I see myself as an honorable man and value that over whatever advantage you think I might be trying to get over you here.
@@Clarks-Adventure I never said you were trying to be dishonest. This what I observed of your comparisons. In short, I was making you aware of the different sitting positions. I don't criticize to make fun nor shame anyone, I do critique in order to help.
Mabe I'm just stupid. But I couldn't figure out which one was the left one or which one was the right one or which side was up or which side was down it didn't make sense to me. so I tried several different ways until it seemed to work and I still can't tell you what I did right or wrong. Do you have a suggestion on which one is the left one and which one is the right one and what what it looks like up or what it looks like down? There was no instructions in the box and I couldn't find any anywhere else you made it look so easy and you only took a half a second saying get the right one on the right side :-) by the way I love your new theme song
If they are the doel-fin product the one with the sticker seems to go on the right/starboard side with the sticker up. Regardless, every one I've seen was a bit of an airfoil shape. The flat or concave side goes down. Hope that helps -C
I know hydrofoils work but you had completely different conditions on the split screen. Doubters are going to say the calm water was a factor in the results.
Well if you were driving you would realize the difference immediately. And actually I had my weight as far forward as possible on the first run without the fin. With the fin I just sat comfortably. I did this video to help people. What would my motivation to lie be? The pennies I get from the Amazon affiliate link? Really? I'm sorry you have had such a life that makes you so untrusting.
@@Clarks-Adventure It’s just an opinion, i’m not here to judge you... nor do i want to, i was just stating what seemed obvious to me, whether that’s the case or not only you know. Truth is they work in some cases but they’re not by any means magic. If they were that exceptional they would have been included by all the major manufacturers as standard. Happy sailing.
@@Thesarcasticmonk I agree - deceptive video. They don't make that big a difference - and yes, I've had them. On multiple engines, multiple hulls, both inflatable and aluminium. Weigh distribution is what was changed here that made the biggest improvement.
I experienced the the same on my little 13" boat when I mounted a 100hp Suzuki on it. It got to plane easier and faster, but there was 5-7 knots of top speed loss
Because I'm not a robot. I'm not lying to you and I'm sad for you that you feel so defensive and that people are trying to pull a fast one. Install one or not. It's up to you, I'm not selling these I just want to share useful things I've discovered.
Was the motor trimmed all the way down? I didn't have good results, lost too much top end, went with four blade prop, less pitch, my two cents🤪,anyone try the spring loaded trim tabs for transome?

Hard to believe that I just watched you put fins over barnacles. Expected more from you. Glad it worked with a dirty bottom and barnacles.
Shearing action on the fins cleaned the barnacles off very well. Just their footprint left.
Better than a scraper. Besides I didn't have a scraper with me.
Also you can't believe the speed of growth here. It's as bad as Tampa bay. Worst two places I've ever been to.
As a boat owner just a quick look at all that growth on the O.B leg (suspect that the bottom of the dingy would need attention too) just a couple of hours with a high-pressure hose, brush and scraper to removing that and give improved performance.
True. It's an ongoing battle here in Luperon. The growth you see on his dinghy would happen in less then two weeks. -C
The inside will be as bad.
Nice boat
I could never understand why guys make videos with the engines and both looking like shit at least clean it before you make your video

Thanks, Clark. So may of the videos showing fins focus on much larger outboards and boats so was good to see it on a tender size dinghy.
Your welcome.
I think fins are more important for small boats like this.
@@Clarks-Adventure yes for sure. More likely to be a power shortage amongst other things.
Thanks for that tip. I’m in. As soon as I sort out a motor for my dinghy (not needing one yet being marina bound for the time being).

Pretty cool. Those fins need to be an integral part in any dingy/outboard purchase....why would you ever want to run a dingy without them.
I have a 10 ft jon boat its fun to drive. Flat bottom its easy to get in and out.
The ship's bell is a nice upgrade from the piercing ping :D
First clean all the lower unit. That has a lot to do with the performance. Second is get a one piece Hydrofoil they work much better. Stingray makes a really good one for a engine this size

Great post Clark
Hi could the tilt of the motor. in. at the prop have done the same thing ?
Sort of but at the with a greater waste of power.
awesome tip!

Thank you 🤝
Aye m8’s, great as usual! What are your experience with seaweed/kelp/sargassum etc in combination with fins like these?
They slope back so imagine they shed what they pick up.
Never been an issue for me.
Had some serious festoons of kelp around a 9.9 Yamaha some weeks ago. Didn’t cut of even on high revs, neither on reverse… Had to lift an reach by hand all the way back in gale force and low tide. I like these fins and probably going to bring a pair, but there are moments where you can get entangled I’m sure.

If your boat doesn't need this help there would be no reason to install one. When I used boats I built and designed myself I didn't use one. No need as the hull solved this issue with it's form.
Talking about building… I’m really looking forward to next part of Emily’s nesting pram built. 🛠
Read it to her. The suggestion has been passed along. -C
Would those help a small sailboat like a Catalina 22 or a smaller sailboat- to stay level when motoring?
No. It's only for planing boats.
...I've just been putting the weight forward at the bow since I was 12 years old...generally carry about 50-100 lbs. of gear + gas...
That certainly helps. And all boats don't need it but for short heavy dinghies this can sometimes really help.
So i have like a 2hp honda engine and im gonna buy a 180cm x 120cm dingi and i weight like 70 kg what do you think how fast can i go?
Don't bother.
4knots.
2 hp isn't enough power to plane, sorry.
@@Clarks-Adventure but i can already Go 6,5 knots in my tube boat
Wow that's impressive. It must be a really low drag boat.
@@Clarks-Adventure i mean it goes 14km/h and google says its 6.5knots
what's the difference with those and a hydrofoil?
Hydrofoils lift the boat out of the water.
But I bet someone named their competition "hydrofoil". If so stupid name , but I expect it would work similarly.
Great Tip....thanks
When you say pins, I take it you are referring to screws/bolts? I like seeing before and after results.
Yes. I screw up what I want to say now again. I meant to say pin it with the screws. Later I call the machine screws nuts.
Hello adventure friends.Can those fins be used on a 21 ft with an outboards? I’m totally new to
boating..-PS thanks for the tutorial.
Sure. It depends more on the size of the outboard. They make bigger fins for bigger motors.
But you could put these very fins on most any motor to good effect. Bigger fin more lift.
Cleaning under the boat will help to
Yes but it was not my boat.
If not a good reason to bolt on a fin
Does it matter if the bolts go in from the top or bottom? What are the chances of them falling out?
No worry of them falling out. I think the instructions say nuts up because the bottom is smoother with the machine screw heads. Less drag?
That is just a guess. Anyone else have an idea?
But I'm certain it will work just fine either way.
Less drag from the mounting hardware is the idea here. You want the least amount of hardware protrusion on the bottom of the anti ventilation plate to avoid drag as you move through the water.
Just got a dinghy to take to shore from my sail boat. At full speed it feels like I'm on ice... I feel like I need a keel lol!! Any solutions?
This will help a bit but if you have a flat bottom inflatable, that's how they are.
@@Clarks-Adventure hmmm thanks for the advice!

You have got to get over it if you want to travel. There are places like here where that can happen in two weeks.
you are definetly underpowered but if it makes you plane you will for sure fo faster...but having a 15hp on my dinghy it just reduce the speed a lot

Wasn't my boat.
His problems
Free hack to go faster...... pressure wash the bottom of your boat!!!
You could trim it lol wtf
Such a short boat with such a heavy motor... Nope trim is not enough.
Who on leaves barnacles on their motor?? ...no man!!
Just a little bit annoying but otherwise not a bad video
Far out what a long winded video
