It depends on what you mean by "small."
If your talking like a 10' fishing boat, than it's an aluminum fishing boat
If your talking like a 20' bow-rider or cuddy cabin, than it's what I just said.
if your talking like a 30' Cruiser, than it's a Sport-Cruiser
The max I consider "small" is 40' and that's a full blown yacht. But a yacht that's on the smaller side. So a Sport-Yacht or Luxery-Yacht.
