@AlanX maybe it would have been more stable if you would have kept the width all the way aft. but that would have changed the style of it.
@AlanX how wide is it?
@BlueBell now that's an idea!
@DCockey Alright I guess I agree that you would need a bit more info to determine how you would do it. What I'm looking for is for a general...
@Ad Hoc if you had to figure it out for a design, how would you do it?
@AlanX thanks a lot! I was confused about what Mr and As stood for in your first post. As I understand it, the first formula is the righting...
@AlanX and MR is minimm righting moment? im surprised its not dependant on the sail area.
Hello all! When designing a monohull sailboat, how do you know the design has a sufficient righting moment? lets say we have a sail of 100...
If it's box like with sufficient weight at the right place it should work. but the design is suboptimal in many ways. obviously the waves will hit...
@Will Gilmore I was planning to have some bolt from a piece of steel in the concrete to the inside of the boat and heavy filleting of thickened...
@Rumars Yes that would work, but there would surely be some welding involved and I'm not geared for that at all. I'm talking about the 1" steel...
@bajansailor Hi. For the picture, it takes some time to get approved and I was advised to put it there in that way as it doesn't have to go...
@gonzo OK. But dynamically under sail, would the wind on the sail act to push the bow more than the stern into the water therefore requiring to...
@gonzo yes I agree. but I've read in some places the LCB is generally forward of the LCG. not sure in what proportion. @Will Gilmore the unloaded...
@gonzo does the center of gravity have to be exactly in the middle, or do I have to take into account that the force exerted by the sail will...
@Will Gilmore 900lbs just boat no supplies or crew. yes id at least put some large rebar in the keel to i can put a few bolt thru to the floor i...
@Will Gilmore this boat should cost less than 5000$ CAD to build so that lead would double the price. But the keel as it stands right now is not...
@bajansailor the beam of my boat would be 5' 6". you raise a good point that I might not be able to build the hull for only 450 lbs if that 4m...
@AlanX : I don't think there is a minimum like that for Canada. that limitation didn't stop Serge Testa apparently! @Will Gilmore : I checked...
Hi all! This is a design of a 12' sailboat with a full keel. plywood stitch and glue construction in mostly 3/8", 900 pounds displacement and 50%...
