There is a huge range of boats 12-14'. A lot of it depends on what you have. I have a 12' Starcraft that works great with a 15 hp engine on it. I had a 14' Sylvan that worked fine with same 15 hp two stroke when only two people a dog and light fishing gear were in it. But, if you put same two people, dog, fishing and camping gear in it, it was a scow. A 25 would have been much better. An old 1940's five horse pushed the 12' along fine with one person, but any gear in it and it would have plowed.
