Stewart,

I hadn't even considered monos when making the post.

Agreed, pre preg is much easier.
It is also a lot more expensive.
From memory the pre preg plain weave carbon was 50% more expensive, the glass was around 500% more expensive while the Uni was actually cheaper. I still have SP Systems pricing around somewhere probably out of date so things may have changed.

I don't know of any cats being built from re preg carbon?
Not even aware of any A class built with pre preg.
I think there are other resons apart from cost but I won't
go into that here, happy to discuss offline.

My personal veiw is that for hull construction Infusion is the way to go when considering, cost,quality and controlling quality as well as ease of construction.

Mast construction:- pre preg is the way to go.

Just the way I see it.
