Klasse erklärt, ganz herzlichen Dank für diese sehr verständliche Erklärung, wirklich hilfreich.

Anyway, power and rpm are not in fixed relation on a marine diesel. These engines are rpm-regulated : the position of the engine control sets the required rpm, and the regulation mechanism adjusts injection (thus power) to maintain that requetsed rpm. Both this and variable pitch on the autoprop make comparisons tricky. Only two comparisons are really meaningfull : max boatspeed attained in various sea/wind conditions under engine with the fixed vs. variable pitch prop (and at which rpm ?); and fuel consumption for a given speed with the fixed vs. variable pith prop (not a given rpm !). Love your pragmatic approach, keep the good work !

Woaahhh hahah never knew you could do that

How are tides accommodated?

Thank you By any chance do you know what type of water supply hose you used or is used? Thank you

When connecting the iPad to the WiFi network, which network device is this specifically?

Indeed. Oxygen robbed stainless will be at the top of the galvanic chart.

It would have been really useful if you had made it clear at the begining, that this app is only available for Apple products. Also, just as a sidebar, you really should learn how to normalise your audio.

Great! Like others already said: the explanation (and not only a video of the results) I've been looking for. THX!

just remember and viuslaise the pivot point of the boat and work with that.....................and more importantly, it is not a race

I keep on watching this from time to time… I have the same set up on our Beneteau 41 and I promise you it’s the thing that I worry about the most. I simply can’t remember how to use that funny little pull out bit of plastic and which setting I need!

insanely beautiful. I'm still going to sail around these parts

Hi! Perfect explanations! Thank you a lot! It would be great also to have your recommendations on stern-to for a Lagoon while crosswind.

Leave one spring aft - much eaier

I wanted to watch this. But YT has these crazy ads that slow playing before it starts. I am not watching because of YT ads.

At only water current can we use same method???

Problem with this manouvr is thta both port engine and starboard engine pushes stern towards dock Same result if not better you can acheive springing in stern spring line

Lovely to see our beautiful County (once again) from a different angle, thank you.

Is there another video that follows on from this one, with more data or a summary of your experiences?

How do we know who is the stand on and who is give way?

I can just imagine an MCA examiner if they asked me to explain Rule 6. " be able to stop before hitting anything" 🤔🤔

There is a way to go in bow-first and WITH the wind, albeit quite laborious for a single-hander: Just before approaching your spot, attach a stern line (in this case port side) to the neighboring finger to slow down your boat and bring it to a stop, then secure a bow line (port side) to a cleat on your finger (not the neighbour's) before gradually releasing stern line and hauling in bow line, in a controlled fashion. This will maintain full control of the boat at all times. Engine should be in neutral, obviously.

Great explanation. However, each approach pushes the boat to the doc, which has risk involved, especially with higher winds. I prefer to tie a spring from windward aft cleat, away from the boat to the dock. Engine forward, steer towards the dock, this moves your whole boat away from the dock, keeping it mostly parallel. Now, gently (!) steer away from the dock. Without any pressure of boat to dock, or any pressure on the crew, your boat will pivot towards the wind. Now, slowly remove the line, keep the tension, and then take her in and sail away.

Great video, Thank you.

Great video, thanks.

I'm binge watching your video's and I must say I am enjoying them very much.

hi Guys, where did you find the info about the Pentland Firth (and its scary tidal streams and eddies) please?

Help. Do you have the rudder vectors backwards? If SB engine is in reverse, wouldn’t it be drawing water over the rudder causing a small force to port? Vice versa with port engine in forward?

Short and very sweet

Minor variation I once heard and that works for me is to pretend you're an opera singer as you extend both arms during the throw while opening your palms toward the imaginary crowd in front. Thanks for the demonstration, this is a good skill to have.

Thank you for going to the trouble of making these videos. Particularly good to see the Irish coast and some of its harbours featured. I can t understand why so few boats make the trip from the Solent up the Irish sea. So it is lovely to get some positive commentary about the facilities, the welcome and the Guinness. Because of the Common Travel Area we are unaffected by the issues that Brexit has presented for visiting France. All you need are a few euros in your pocket and your ID. Fair Winds.

Gode katamaranvideoer, som forklarer veldig godt!

Wow I love this content

Can you put your bank details up please. I’ve got £1500 for you 😅 😂 And if it works for you, then I’m going to do it too! I really do NEED a Kraken 44! 🤣

My wife reckons she’s the captain too! What’s the app you’re using showing the tidal streams?

Great video. I haven’t even got a 349 but couldn’t help watching it! (Must be the engineer in me)

Cost aside and even cause aside, I’m just glad that you found it.

we have just spent a month sailling with an autoprop after running a folder for years and a fixed 3-blade before that. Totally transformed motoring and especially motor-sailing performance. Very nice to see a product that fully lives up to what the manufacturer says, if not exceeds it. Kicking my self that I did not change earlier.

Good on you my friend. This is a great effort. Thank you

why nobody thinks to post a video on very hard tight dockings? many boats have to dock front or rear ended with boats either side with tides rushing out and in and strong wind

As an engineer. Great explanation!

Round Ireland :) great video

I am finding the buoyage rather confusing. The starboard and port marks in the channel going over the bridge seem to be reversed? I dont get it, although i havent got the chart so i could be misunderstanding your approach? Anyway thank you. James

neat!

There are various explanations for "prop-walk", but I don't think that the difference in water pressure at a different depth of 30 cm is large enough to explain this phenomenon. I think the following physical explanation describes the phenomenon more accurate. The prop pushes the water in a circular motion (clockwise or anticlockwise) and also pushes a water-stream forwards or backwards (depending on the direction of the propeller). The water-stream is equal to prop-wash and the prop-walk only corresponds to the circular movement. The circular water movement and the generated water pressure is more or less the same in all directions and decreases steadily depending on the distance from the propeller. The difference in water pressure at a depth of 30 cm is ridiculously small. But what makes a big difference - and this is a more accurate physical explanation for prop-walk - is that the circular water movement encounters resistance below the hull, which builds up a higher water pressure that pushes the hull either to port or starboard. This also means that every prop generates a prop-walk in both directions (starboard AND port) depending on whether the propeller is rotating forwards or backwards. The difference is, while moving forward we do not notice the prop-WALK because the prop-WASH on the rudder is many times greater. Maybe we both are right or wrong with our explanations and maybe in anear future somebody will make a study about this topic. Cheers a.h.

nice video, very informative. Thanks for that. It seams that this instructor like to teach the hard way. 😂 There are a lot of advantages to do it the opposite way, especially with modern monohulls. 1. Much easier and better control while steering stern-to against the Wind to the first buoy. 2. Easier to pick up the windward buoy from the stern. 3. With two stern-lines from both cleats attached to the first buoy (windward) you have a perfect controllability of the vessel to pick up the second buoy (leeward) from the bow. 4. Drop the buoy and leaving the harbour much easier. Disadvantage: The wind is blowing into the cockpit, this can be annoying.

Have had a few nightmares in my Halmatic 30 going aft out of the berth.....lol. Best part is learning everytime, thanks for the tips will try this wee cheat.

Very helpful video. Thank you for this. I am just about to put into practice what you have advised for a single engined outboard on a small (24 foot) catamaran. We are really tight into the pontoon in Torquay Council pontoon so very little space fore and aft to manoeuvre or swing. Also we have an overhanging dinghy on davits so I think I will stick to using your first bow method to get out. Any extra tips for a catamaran as you said that you had also had experience with cats?

Another great video with more good tips about using Port Erin as an alternate destination considering the wind, and the advice for anchoring safely. Im glad you got to see a small sample of the island and if next year permits, I'll be more than happy to give you both a few days to show off a few more of the sights. Have a safe onward journey (I'm late, so your next video is already waiting for me 😊) Cair Vie
