Model from a study plan

Hi everybody,
I wanna build a catamaran of about 40ft, but first I will make a model to see how big the problem is , and then start planning. For this, I'm about to buy a study plan from BRUCE ROBERTS. Do you think this is a good direction, or do you have any other suggestions? I am completely open to suggestions .

Thx,

Jardel

 

Buy a plan for a beach cat and build that, you will have a fun machine to sail on and it will give you an idea of build times etc (a 40 footer will be 5 to 10 times longer to build). Richard Woods, Selway Fisher etc all have small cat and tri plans. If you look at Duckworks magazine free plans on the net you will also find free full plan options of smaller cats or tris. Good luck.

 

Building scale models can be helpful, but what is the objective? Bruce boats are a known, they have been built and work. I dont think a model is going to help you figure how much work its going to be, anything this size is a big undertaking, the work really does not scale.

 

Thanks for the tips, @oldmulti. I appreciate it.

 

Hy @skaraborgcraft,
I'm an architect, and I want to have a little fun until I have a consistent plan to build it. But thank you for the advice.

 

Power or sailboat?

I have not bought study plans from Roberts but you don't usually get offsets or enough details to be able to build a scale model. You get general arrangement plans, sample construction drawings, material lists, this kind of stuff. It's easy to understand that there has to be a difference between the 50€ plan and the 1000€ plan, if the cheap one has all the details what's the expensive one for?

 

Hi @Rumars,
Sailboat. Catamaran 40 ft.

I received an offer of $195 for a full plan in CAD. I think it's a good offer, but I didn't expect to spend this amount right now (I'm still a student finishing my master's).

 

bruceroberts is having a fire sale on full plans?
His website only mentions one 40ft cat, and it's a power/sail model. If you like it and understand the compromises why not, but if right now the cost is to high for just dreaming, keep your money in your pockets. You can just as well dream by looking at construction pictures and consulting materials lists available for free on the internet from other designers. The libraries can provide reading materials about boat construction in any method.

 

Hi @Rumars,
I don't know ). The only thing I asked him was: "Am I able to make a realistic scale model to aid in planning a future construction project?", and he replied with this offer. Maybe it's not a full plan, probably something to allows me to make the model (in DWG). I really don't know. I'm new to this field.

 

Read this are there are a lot of people just like you who asked the same thing.

Look at all the threads there are heaps.

 

What is the main goal, to build a boat or to go sailing? The world is full of boat projects that never got finished. Some are from people that got tired, lost interest, or run out of money. Many others is because the original builder died or got too old to go on. Realistically, it will take you 10 or more years. At least half of that time will be taken on learning and then redoing mistakes. The cost of building also will include storage of the project which may add enough to equal the cost of buying a used boat today. How much experience do you have sailing? A 40 foot cat can be a handful.

 

I suppose the only thing you can say is that it took you so long and you don't think anyone could do it in less time. But that experience doesn't allow you to assume that someone else, with different means (intelligence, training, material resources) should take as long as you. IMHO

 

I would be looking elsewhere for more modern designs, you have given virtually nothing to go on but I would suggest Woods and Simpson for solid old school cruisers or Schionning and Grainger for more modern and Kurt Hughes has a range, Wharram for old school traditional.
Roberts has very little street cred in multihulls.

Hi @guzzis3,
I'll try to summarize all the answers here:

Thanks for the tip. I'll look it up.

It's not aluminum. It's fiberglass + epoxy. The plan from Roberts includes Fiberglass and aluminum.

I hope to make it as soon as possible.

A smaller can compromises habitability. It's a "sailing house" .
