Sail Boat Plans 34 to 40 feet Round bilge

Naming rights are for the trademark name of the design. It would be consider fraud for a person buying a design to claim to be the designer.

 

Thanks for the replies. I would not consider designing the boat entirely by myself. I would hire a NA. But I would provide plenty input in the way of lay out and design. I suppose it will depend on the costs involved and the difference between plans for a single boat and owning the design outright.

As this would be a one off design I will be paying for the designers time hence the thought of recovering the costs.

It will essentially be my design, refined and detailed by the NA. This is how I build my house I designed the layout and external design, materials and construction methods. Then passed this to the architect who ensured it complied with the building regulations and then to a structural engineer who detailed the structure. I consider the house my design and think a similar method would work for building a boat.

 

Wondering about manufacturers brochure figures for displacement. Would the figure quoted include the anticipated weight of crew. Stores. Fuel. Water. Equipment etc. Etc.

Hanse 415 quotes a displacement of 8900kg

 

It is very likely that they do not include all that because the tendency is to show that it is a very resistant but very light hull. In any case, you have to analyze the manufacturer's brochure well and ask him to explain what he includes in the light ship weight and in the other items that make up the weight.

 

It is no different, but it is also very different. Since you are conflating "a layout to your preference" to one that is an actual "Design".
As you have already noted... you needed an architect a structural engineer etc etc.. these are the 'Designers'.

The simple way to think of it...ok... you draw your layout, you like it, it suits what you want... BUT... will it work... will be safe... will be structurally sound.. will it pass rules? If the answer to any of these is "no" or "no idea", then all you have done, is a "layout" of your preference. Everyone has their own preference, everyone! A preference is not a design, it is merely that.. your personal preferences that are illustrated on a drawing in either 2D or 3D.

And the acid test is, let's say i look at your drawings and say hey, that's great i like it. But.. i want to move the windows from A to B and make them bigger.. the stairs from fwd to aft and make the main cabin longer....as my preferences. But my preferences may make the whole "Design" difficult to achieve, as structurally it may no longer work...or may not pass regulations...so, who will do that part of the "Design",...you??? But you didn't do that for your own, so you can't add any value to the conversion to my preferences....but also...according to your logic, the 'Design' is now mine. As it is "my preferences", I designed it!

A final thought.. history is littered with endless claims from "inventors" and "designers" of: I have the best design since sliced bread and i will make loads of money from it as everyone will want one.
Having a good idea, or your own idea or believing your idea is marketable never translates into the real market. Why.. because the markets' preferences are not yours!

Just as Sir Clive Sinclair and his C5....

 

Hi. Ad Hoc
Thanks for your informed input. It is welcomed I agree with much of what you have said and disagree with much of it as well.
I suppose it comes down to how much information I supply up front to a NA if just a rough sketch and a few paragraphs then indeed he would be designing the craft. However if I provide a lines plan with LCB and LCG, a sail plan and a proposed structure and then ask the NA to finalise the design I accept it would be more accurate to describe the design as jointly designed.
What I have in my mind is not a C5 of the oceans!!! rather a modern monohull fast cruiser in the 39 range.

 

Ian, have you come across the designs by Mike Pocock?
I think that for what you want in a cruising yacht, his designs probably are the closest to what you have in mind, and could be a useful starting point for reference?
Sadly Mike crossed the bar 5 years ago, but his wonderful sailing yachts live on.

John Rodriguez sold Al Shaheen a while back, but still has details of her on his site.
OK, she is aluminium, and 2' longer than than your 40' limit, but I am sure that she would come pretty close to what you are after?

Mike also designed Blackjack, which he later bought from the original owners, and took her on a cruise around the world.. Lumberjack in the link below is a slightly larger version of Blackjack -

Thanks. I will check out your links. Cheers.

 

Starting to get some lines onto paper and enjoying some light reading and research.

I was hoping to get to some boat shows for some ideas and inspiration but of course that’s not happening just now.

 

It looks OK, but really dated. For a new design to be attractive it has to stand out. I don't like Axe bows, but they make people look. Those lines are a typical boat at any marina. I know my opinion is rather harsh, but it is the reality of marketing. What answer do you have for the question of: "what makes you boat different of better than the rest?".

 

Hi. Gonzo
Beauty is in the eye of the beholder. It don’t look dated to me

I’ve got study plans I bought in the eighties which are still for sale just now and they look dated to me.

looking forward to starting on the interior layout.

 

Ian, could you perhaps post some new photos of your plans please?
I tried saving copies, and then enlarging them, but they are still very faint, and I think there is a fair amount of glare or reflection (did you use a flash?).
Which existing designs are you primarily using for reference?

 

Hi Bajan

don’t have access to plans right now.

here are some pictures of an 8ft spline model I built. After lofting a 2ft boat then an 8ft boat I decided to build the model to fair out the lines in the stern where I was having the most problems.

I don’t do CAD I Probably should take The time to learn. But this was more fun.

I’ve looked at just about every current 40ft production boat for ideas. Like a fold down transom not for swimming but for access as my boat is on a mooring. Don’t like twin wheels well aft.

 

I am not a CAD person either - I am much happier on an AO drawing board. I have used basic design and stability programs in the past, and did a couple of evening classes in Autocad (one in DOS, one in Windows, both a long time ago now) but didn't keep it up, and I don't have Autocad now on my computer.
It is very satisfying doing a drawing by hand - but I appreciate absolutely that CAD is so much more versatile and quicker once you know what you are doing (which I don't).

 

Interesting topic. I have not read all the posts in detail but there may be another small aspect to keep in mind - Units.
This observation may be dated but if you are used to using Imperial (feet, inches, pounds etc) and the plans are in S.I. (ie:metric) (or vice versa) there could be another learning matter to deal with.
