I made a full scale template of 0010-34 and it looks mighty thin (maybe structurally?). The 0012-34, would it be a terrible substitute to gain a...
I have charted out 6 sections 1/4 scale. I had charted that one out too, it carries it's thickness a little farther aft, doesn't it. The nose...
Is this a true lifting keel, that raises straight up, or a swinging keel? If it is a lifting keel, I could imagine the difficulty raising it at an...
For this keel that will "live" in a world that flows by it at 2-6 knots 95% of the time, would a NACA 64A010, 0012 or 0015 be of best...
thanks guys, I will have to go with a chord of 24" and a span of 38" (limited b y boat design) and use the NACA 0015 template. I have to get...
You are in the same "boat" as I am, making a keel from scratch. Yours will swing and mine will drop straight down. Should be interesting, a good...
From a non-designers view, but more of a survivalists, how long could you expect to stay in a huge squall at sea when you really couldn't outrun...
Thanks, I have some constraints to max draft. I would have to chop a slot in the deck to get a longer keel to retract into and out of the cabin...
The 0012 is 5.7cm wide (2.25") The 0015 is 8.9cm wide (3.5") On paper, it looks like a huge difference. I have the full size template plotted...
The NACA 0015 would be 3.5" for a 22" wide keel. Looks chubby on paper, but I guess if I have to go shorter (30-38" long), then I might have to...
Would a Hobie 14 rig without jib, but including a genaker work? You can find Hobie parts around here cheap if you dig around a little. I am not...
It looks a little like a Mirage 5.5, but I can't Google anything about a Hyundai sailboat. The keel could be just a swing keel, like a Catalina...
Hey, you are hiding something. You said you were converting it to a casual daycruiser. Why would a casual daycruiser need all those math...
Are you reconfiguring the keel for a lifting foil? I am in the process of doing my homework on my boat. What Naca section are you going with?
Check the spelling, google won't let you search by that name, they want you to change it to Hyundai so you can see all the car sites. Do you have...
Thanks Brent, your suggestions are what I was looking for. I have to decide wether to cut a slot in the cabin top (which has only a 10% chance of...
Wow, you are way above my ability! Other guys here will be able to tell you how much you are going to put into replacing the deck, and whatever...
Thanks Brent, I wish There was a Holder around here. I think an Ultimate 20 is similar too. The current keel is very wide at the top (41"), but...
I am not sure about the currency exchange rate where you are, but $11,000 can buy a really nice boat that has not been fired up in most places (of...
Due to hull constraints, it looks like the keel will be 22" wide, and 46" long with 30" hanging out the bottom. The Naca 12 section looks about...
