Cheapest cost to self-design & self-build a 45ft sailboat

If we estimate the gross tonnage of a 45' keeled sailboat and use 12' beam and 6' depth, we get

.375 x 45 x 12 x 6 /100 = 1.215 (?)

Plug it into oced.

Cgt = 49 x 1.215^.67 = 55.8

56 x 70-90 man hours per say 80 is 4,480 hours for amateur go it alone.

Perhaps CDBarry can give us the interpretation and hours estimate for the boat in question as I am guessing.

I think the OP gave up.
 
I never understand these dreamers in the first place. Its common knowledge if you spend one week driving round every boatyard and marina on a stretch of coast you'll find a distressed yacht at a bargain price to refit way cheaper, quicker and less risky than designing, building and equipping a home made boat. I really don't get it..

yeah.. but those boats have cooties

Yes, but for sure less cooties than the boat design and building process the OP talked about in post #1 & #3 . . :eek:

— better the devil you know than the devil you don't — used to say that it is better to deal with a difficult person or situation one knows than with a new person or situation that could be worse —

Note ‘‘could’’ is ‘‘will’’ in this case from all the OP's posts so far . . ;)
 
You can build a thousand square foot house with 20 or 30 facets on the outside. You can also build a thousand square foot house with 5 facets. Likewise, it mostly depends on how you think you're going to fit the boat out.
 
Not at all. A structurally sound boat is based on good design and construction techniques. The fit out is not as relevant as long as it doesn't overload the boat.
 
It says . . . ‘‘ New construction method ’’ . . . ‘‘ No one has done this before ’’ . . . and more snake oil . . . :eek:

Check 1981 patent US4282617A and the 5 drawings there, which are also to be seen in this PDF of the patent.

Also the type of dart cutouts in the video and the hull shape look as bad as an old Brent Swain design, which can be much improved.

And the wooden building jigs in the video aren't needed at all for the shown origami boat building method.

Brent Swain long ago but after 1981 at the built of Sailing Vessel MOM

‘‘ Brent has developed a unique construction method that is called "origami" as the hull is "pulled" into shape. ’’

Also snake oil, see the above linked 1981 patent . . o_O

I do like however the Origami YAGO Project which is different in many details . . .

Does this origami technique has it's limitations in terms of bow type? It seems to work fine with these traditional designs (spoon, raked etc), but more modern plumb bows are impossible to do with it?

Plumb bows are actually easier, spares a lot of cutting..
 
The angle of the bow does not make a difference. The only thing that changes is the angle of the cut in the panel. Maybe an extreme shallow angle would be a problem.
 
I think the OP gave up.
considering the nutiness of his original post: is this a surprise? It qualified perfectly for my category: "Fool or troll"!
 
Be kind. He's likely neither a fool nor a troll. He did not know the answer so he asked. What more do you want? If new folks come in, not knowing the answer to their questions it's not something to mock them for. Are we going to gatekeep the forum where the only folks allowed to join are people who already know the answers? Folks who meet that criterion won't join because the forum has no value for them. The best members on here genuinely enjoy teaching, explaining, sharing their hard-earned experience with the next generation of boat enthusiasts and dreamers. If we drive those folks away, as the forum far too frequently does, there won't be a forum anymore.
 
Thanks Dog Cavalry for that most decent summation of why we are here

I too am sometimes annoyed by dreamers who insist that they will do one thing or another when neither is practical and sometimes impossible. When I was in eighth grade in school I was pretty good at math and I thought I knew everything............later I learned that differential calculus is not quite covered by eighth grade math. I did not know what I did not know. That is going around and we need not be too critical of those who are less informed.

(disclaimer: My patience dissolves when politics becomes the subject at hand........Thank goodness, and our administrator, that politics are not part of the forum content)
