Hello,
I am owner of a custom built trawler based on a Lang hull. It is a 30 feet aft cabin trawler with flybridge. I bought it recently and I am more than pleased with it. It ismpowered by a Acadia diesel engine, naturally aspirated. At 1800rpm it moves me at a bit more than 7 knots for an average of 1.5 gal/h, pretty good for my wallet and I like to take my time when cruising
