Saying a Model that's easy to build. if you mean simple vacuum moulded kits that can be built in days/weeks,that aren't too detailed. There's HFM Marine, Krick and SHG for very basic. More detailed are Deans Marine, Caldercraft, Model Slipway. Try and find a local club for idea's.

Have a look at these.
