Welcome aboard tomtom 56. Hendo will appreciate your interest.
Everyone has their own idea of a trawler. My thoughts: the hull looks a bit like a fishing trawler, it usually operates, as Mark says, slowly,at hull speed, ie around 8 knots, often has a displacement or semi displacement hull, is reasonably fuel economic, provides some living accommodation, even luxury on some, and is often a traditional looking boat. Some are actually converted trawlers.
To me, a Grand Banks 36 is, a Riviera with fast planing hull is probably not. Which is not to say a Riv is not welcome, it most certainly is, they are great boats. It can pretty much mean what you want it to, it`s a very elastic term. Seeing pics of members boats will help, you`ll see how much they vary.
