Cant wait to see how you end up making your keels. I like how Cpt Yrvind has done his latest one. It will be interesting to see how he puts it onto his boat.
I think the more outboard keels might be better if they are farther from center but could also offer the benefit of less drag when the hull heels as only one keel remains fully submerged. Curvature of the hull seems to be an issue with a design like such, but I think this can be solved by moving the aft end of the keel inwards a little to have it under the hull while the front end might be located flush to the side of the hull ? --- But that's just my personal first impression and my thoughts while watching...
Hello. Just find this topic. A few things you should keep in mind concerning the twin keels: They are a bit more tricky to install than a bige keel. They are more expensive. If the boat is tiped over, and be upside down, which can easily happen on so short a boat, one keel work against the other until it pass the vertical axis. In case you run aground accidentally, there's no way to tip the boat and make her free. On notable exception of twin keelers with long, thin and... rather deep keels, most of these sails like a pig to windward. They are great for standing on the dry but a single keel, long enough, and a pair of legs work well, too. Anyway, considering the size of your project, the draft of a bilge keel would probably not exceed 75cm. Will you dare sailing her in so shallow waters considering the weight in cruising configuration?
I like the twin keels slightly angled out ward. You will be looking at sail plans. their are better ones than the macaroni. In a small boat you don't want to have a lot of heel. The things that apply to larger boats don't serve you well in a small boat. You in one of your videos talked about shorter masts. You should explore that further.
i knew i saw that boat before the one in video clip the french guy i saw a tour of his boat extraordinary man and his distance travelled around the world it was the chicken on his mast i remembered a local artist on his home town goes around painting chickens everywere and asked if he could do one on his boat and he told him he was crazy but that makes two of us 😂 go ahead and paint
Hi ! A thought... I understand all the benefits of "normal" outward angled twin keels. But ( maybe i am wrong ) there are a safety-benefit with a " inward angled" twin keels. When the boat heels over, then the already angled lee keel lose traction and the boat slips a little sideways. If the keels are wide a part. It´s like lifting the daggerboard a little in strong winds in a dinghy.. I am going to test that in my little dinghy, two slightly inward tilted daggerboards.. Do you need to compensate for balance when furling the sail, small daggerboard? I like your boat ! 👍 I am only curious 😊
Thanks. For simplicity's sake I'm sticking with twin keels that do not move/retract. I've never seen twin keels angled inward. Check out OCSS-007 I go into the twin keels more there, there are more reasons the outward cant of the keels makes sense. The article in the description there even goes into how it affects the bow wave, improving speed, etc.
Been following your build the whole way and was wondering where you bought this pvc foam from. You bought directly from carbon core or somewhere else? Thinking of using it to build a dingy for my sailboat. Thanks.
It's such an investment already to build a boat, I would spend the extra money on a good quality rigid foam that's intended for structural use. I've considered using that kind of foam on a simple kayak build, though.

Great design improvements! I’m thinking of doing this sailboat project myself!
Go for it!

Keep watching, I get more into the rig I want in later videos. I plan to have a mast 21'6" above the deck.

Haha yes, he said if he didn't stop him, he would cover the whole boat in chickens.

May I ask where you bought your pvc foam sheets?
Where can I get the plans
I don't have plans available at this time.

Yes I bought direct. I just recommend getting a few quotes to include shipping and go with the cheapest. There are a few suppliers out there.
@@ocean_capable_small_sailboat thanks.
Hi captain Perry, is it possible to use pink or blue foam (Dow's) to build this boat?
It's such an investment already to build a boat, I would spend the extra money on a good quality rigid foam that's intended for structural use. I've considered using that kind of foam on a simple kayak build, though.
Very nice, print it 3d
That PVC foam is nasty stuff, you should absolutely wear gloves and a respirator when handling or cutting it. Highly carcinogenic
You should also have a decently ventilated work space, its off-gases are harmful too
