ship hull blanks or bodys
I see from your profile that you are resident in the USA. There are suppliers in the UK and Europe but transport costs may make them costly.
Robbe used to do a kit of a similar vessel but at about twice the size.
Many hulls are made of fibreglass so would they suit your purpose?
