build a wharram or a Prout 37?

Thanks PI Design

This is something I keep thinking over...

I have access to the moulds - I have knowledge to build this way ...it's cheap with fibre glass...

I don't have plans to any other large cat (Wharram now too small)- or knowledge...

Very hard to decide. So many people are telling me that it will take 3x longer than I think, 3x more expensive than I think... I am now questioning myself.

 

In that case, I'll pass on some sage advice that others have been throwing at me:

Those were in reference to http://www.boatdesign.net/forums/pr...ing-around-10-m-trailer-cruiser-17597-11.html - in which I have been endlessly debating variations on a boat I want to build, and have yet to actually start building.

There comes a point where you just say "dammit, I want a boat, I'm going to start". You have moulds for the Prout and you apparently know how to do glass layups. (Learning how to do infusion might be worthwhile, especially if you're going to be building short-staffed...) Yes, it'll probably take longer than you think and be more expensive than you think. If that worries you, you can always sit down with MS Project and Excel (or the equivalents of your choice) and start making a thorough schedule and budget, including every cleat, every fiddle rail, every stanchion base, etc. Or you could go all Buehler-style on it and just start building, fabricating pieces from scrap wood and metal as you go.

Of course, you could be like me, and sit around here talking about building without actually getting started. (Although I have an excuse- no money, no space, no time!)

 

Catabolic: yes, it's a cunningham; very useful for controlling the shape of a sail.

It's very tempting when you have access to molds, it seems more simple. It's not so true.

First: molds must be in very good shape, straight and with an acceptable surface. If the molds are old or worst have spent some time outside, maybe it will need some fixing. Waxing huge surfaces and polishing until having a mirror takes time...
Second: If you are short handed or alone, polyester in molds is the worst method. Let me explain: polyester in molds is a method for a team of experienced workers. If you want that the layers of glass/polyester have a good bond between them, you have to make the layup fresh on fresh, or to sand each layer prior applying the next. Rather exhausting, as that means you'll have to sand huge surfaces. With a non blushing epoxy, and working fast it becomes a bit easier as you have more time between layers but it's very expensive.
Third: demolding a 37 feet boat is sometimes a not very simple task if you're short handed.

In this particular case it's a lot of work, and expense of materials for making a boat ALREADY OUTDATED. Its value is close to zero.

When making a boat alone or short handed, plywood is a better material.

 

all finished

I've definately canned the idea.

Looks like it is a case of saving up and going the ply route - those Easy Cats do look nice inside.

We'll see...

Thanks guys.

 

You're welcome and good luck. I wish you the best.
