Hello Dave
Welcome to our happy band
Without knowing some local history it would be difficult to suggest a subject.
Perhaps a better way to approach your problem is to ask what kind of boat / ship would you like to build, i.e. speedboat, cruiser, fishing boat, yacht, warship, cargo ship.
After choosing a type from this basic list the next thing is to consider how big a model you would like to make, i.e. 12 inches, 2ft, 3ft, 4ft…..etc.
When you have chosen a type (i.e. fishing boat) and how big you want it to be (i.e. 3ft) then we will be far better able to give you plenty of options.
I hope this helps
Paul
