In this episode I re-think and re-build my 1/10 scale model of the boat, adding a scow (rounded) bow, twin keels, and a skeg to protect the rudder. I quickly discuss the advantages of a small boat, and the above changes I’ve made.

I built one, just like that, put in a harbour and went for groceries. When I came back, the cardboard had dissolved completely, only some masking tape was floating on the water. 😂

I love the design. I've been considering building something similar. The swaggie is a nice little boat with lots of room and I talked to the designer, he's a cool guy and the boat looks solid. I don't have the expertise to design a boat like yourself but I think you've got a solid winner.

Twin keels are definitely the way to go.

@Seafariireland Жыл бұрын

Bilge keels provide more efficient lateral resistance when angled outwards and outward angled twin skegs/rudders more efficient when boat heeled. All modern bilge keels and twin Skeg/rudder systems now like above. Good luck with design and build. Ray, Kerry, Ireland.

@thematronsmilitia Жыл бұрын

What will your ballast to displacement ratio be? I want to build something with minimal materials cost but bulletproof for an ocean crossing, and I was thinking for speed and stability I'd want a 40ft boat. But you gave some good reasons why smaller can be better. What about speed? Sometimes it's helpful to outrun a storm rather than getting tossed around by it. What kind of speeds do you think you'll be able to get out of it with such a low LWL?

@EchoLog Жыл бұрын

I'm all about stability and deck space with catamarans but I want a single hull that'll plane like a bayou air boat! Scow bows and twin keels interest me for these reasons. Cardboard design solidarity.

I am not a big fan of spikey boats hence my liking for Dutch Lemsteraak. My estimation of scow/Lemsteraak bows is that they have the same space a boat one third longer. Something to consider regarding marina fees.

I like the twin keels. When heeled, the windward ( in the air) becomes heavier.. I am building a 8foot "sleep in" D5 dinghy with twin dagger boards inside the gunwales. They can be short and be used as a "reef point" when the sail can not be reefed. As Yann said the scow is probably the best form for a small boat.. Good luck!

Thanks. You plan to sleep in an 8' dinghy? You put some board over the seats at night and sleep on top of that, is that the plan?

I've been catching up on the videos, but as I look at the skeg and keel, I wonder if a more gentle leading edge might be advantageous. To my eye -- an amateur's eye -- it looks a little steep and I'm wondering if it could be a less severe angle? I'm imagining what it would be like to beach (or ground) the boat and I think that the more gentle the angle, the less shock/stress there would be to the boat. Out of curiosity, what do you think? (I'm always trying to learn.) What is the benefits/trade-offs to the angle of the leading edge of the skeg and keels?

Call me crazy but id like to add a keel of some sort to a Macgregor 26M , id also like to make a Pacific crossing in that boat just because people say I can't.

@kamimo2930 2 жыл бұрын

I would also prefer the new design. What I am missing is a water deflector in the bow area, because with the gently sloping deck, spray will probably wash over the deck unhindered. I wouldn't like that as much, because that would already limit the use of the central hatch significantly, even in light seas. I also ask myself why so much bathtub is necessary in the rear. Couldn't the rear area actually be shorter and also have a water deflector to the sides or even disapear at all, creating a house all the way to the rear (containing a second larger sealed hatch for access to the rear outside)? --- Just asking myself what you think about that as an alternative ...

@DavidPaulNewtonScott 5 ай бұрын

There is an argument to be made for no cockpit. More interior space and impossible to take on water. If pooped it will rapidly clear.

Maybe a Laydon Paradox? I am building one with the intention of sailing it on the high seas. My main priorities, slightly different than plans Water tight cabin with exterior rudder/tiller and watertight hatch. 400 extra liters of bouyancy with water tight forward and aft bulkheads. Chain plates for JS-Drogue Basically Roger Taylor(Ming Ming) philosophy for unsinkable watertight vessel.

@ocean_capable_small_sailboat Жыл бұрын

I like Paradox's a lot but I've only heard of them being used for light coastal cruising and hops to the Bahamas in good weather. Well, Yrvind has built boats with the same kind of chine runner flat bottom and has sailed them thousands of miles so if you prepare it well I'm sure it can take you far. Best of luck.

@georgewashington7444 Жыл бұрын

Great channel. I didn’t realize you are quite a ways into your build since this was the first video I watched. The Paradox community speculates it could make a crossing CA-Hawaii or Mass-England but no one has tried it yet of course. I plan on doing one of those routes June 2026 after sea trials on my home waters of Lake Erie 2025. I will incorporate some of your ideas into the modified Paradox. Cant wait to see your boat get wet and make some miles!

That's great! I actually incorporate some ideas from Paradox's in my build. I have refered to those plans and build pictures for ideas before.

I too really like your design and appreciate your explanation of the design decisions. Are you going to sell plans for your design? I am trending somewhere between your boat and the Wave Rover 650. I started sailing a sabot in 1958 #225. I love small boat sailing and am more familiar with your sail plan than the junk rig of Wave Rover. I will be curious to see how your reefing system works out. How will you have an anchor light with a rotating mast ? Thank you friends.

@ocean_capable_small_sailboat 8 ай бұрын

Anchor light goes on a pole on the buoyancy arch. If you'd like to build it seriously, just write me at my e-mail and I'll send you some drawings. You could start with a simple cardboard 1/10th scale model and see how you like it.

Love your design although got to have twin rudders! I had fantasies about a boat like this although i feel a keelson would be better along with twin kick up rudders and a fold out foil kite powered option with 2 removable free standing masts with mounting pointe on port and starboard not centered! Dose that sound crazy enough for you?

Pretty crazy. I thought about kite power, but I used to kitesurf and they require constant attention. I'm not sure how it would work for long passages.

@tincoffin 9 ай бұрын

I don't want to put you off but you may be heading into trouble. The disadvantage of the scow bow is upwind where the bow will stop the boat with every wave. The Open 60s & 40s you mention get around this problem by being able to cant the boat to one side using water ballast or a canting keel to get a better underwater profile and and also by keeping the bow well out of the water. They are able to make it work by extremely clever design. You are further handicapping yourself with bilge keels whose great disadvantage is greater wetted surface area, they are generally slower. Unless you intend to sail downwind all the time you may find it doesn't work. I have no doubt you know all this as I am no expert.

@ocean_capable_small_sailboat 9 ай бұрын

Baluchon made it around the world with a scow bow, making ocean crossings in reasonable times. So, it's been proven to be effective, even if the boat is only 14' LOA. Going fast isn't really my priority though.

Pretty subjective. They're great for inland use, but I wouldn't want leeboards for offshore sailing. I prefer to have fixed keels with lead on the bottom.

@DavidPaulNewtonScott 5 ай бұрын

@ocean_capable_small_sailboat A good point about twin keels is they increase the moment of inertia so the boat will roll like a much heavier boat. Leeboards can also be weighted.
