Self Designed Yacht

[TheMoodyMonk]

frame-less is an option i may consider later on, maybe in a second project, but for now i'm sticking to a framed yacht. hull design for me at the moment is proving very difficult, i think its something i will gather over time. i am how ever going to design the interior fit out, electrical and propulsion fit out as well. and possibly even the rig

well, you asked for it...................



sailing almost all year round, and selling more than one per week............

and you sail proper ships Richard. Cool electronics, wonder of BS would identify half or even one of them and the same may be true for RWatson...

She is on the market Wynand, if you want a toy......................


57 ft. Passagemaker / Trawler for sale.

But I don´t want to hijack this thread any longer.

how about a traditional 40' sloop eg, top sail, stay sail, gaff rigged main with topsail etc saw some pretty pictures

(not to mention that i am a tad of traditionalist when it comes to design and architecture)

Plans are free in his book. Easy to build in steel if you'd prefer.

Ahh !



Spent some time.. well a lot doing up some initial hull concepts what do you all think of this one ?
I have uploaded most the pictures.


Length over all : 40.000 [ft]
Beam over all : 12.157 [ft]
Design draft : 1.600 [ft]
Displaced volume : 215.85 [ft3]
Displacement : 6.166 [tons]
Total length of submerged body : 32.556 [ft]
Total beam of submerged body : 9.894 [ft]
Length on waterline : 32.556 [ft]
Beam on waterline : 9.894 [ft]
Waterplane area : 225.69 [ft2]
Waterplane coefficient : 0.7007
Waterplane center of flotation : 18.550 [ft]
Entrance angle : 22.405 [degr.]
Transverse moment of inertia : 1304.2 [ft4]
Longitudinal moment of inertia : 12983 [ft4]
Lateral area : 37.077 [ft2]
Longitudinal center of gravity : 21.403 [ft]
Vertical center of gravity : 0.954 [ft]

If you say its crap its crap, if it wont work i wanna know. be blatant, harsh criticism is good criticism

to read some comments on metal boats and the different properties of the materials involved.

Enjoy ! You will probably live longer for it.

But consider, say 60% of the worlds boats dont enjoy the benefits of formal naval and engineering design. Boats ranging from the builders of "Kon Tiki" - (how many "I am going to build a raft - how big should it be" threads have we seen) , to Indonesian fishermen desparate for a catch, to the builders of the Dhows that dont have a plan between them and build to suit the shapes of the roots of the trees, the "innovative" Chinese fishermen that feature from time to time in these threads etc etc

I have been following the BS threads, recently and in past years. Lots of unanswered questions, and BS is no academic - but ....

I would bet money he has travelled more blue sea miles in the last ten years on boats that he has built by himself, than any one of his antagonists. Am I wrong in your case ?

how you know that? you believe everything you read ?
how much are you willing to bet?
careful if you loose

That is a great website.

In regards to the design software, since you are a student I think you can get Rhino for less than $200, not a bad price and you can continue using it after your graduate.
