I dont agree with those who tell you to choose trawler. This boat is excellent for living aboard in the med, where most harbours are about 100 nm distance between them in the East about 50 nm in the West area. As for the engines I have driven both 64 Manhattans with smaller 800 and 1050hp MAN engines, and to my surprise the small engine version rides a bit better. With 1050 engines the boats rides very bow high and is more nervous on speeds abou 25 knots. The boat also slams a bit more in anything over Beaufort force 4 1.5 meters plus of wave height. You should top 32 to 34 knots with those 1050hp MAN this with a clean bump and good well maintained engines. The 800hp MAN top about 30 knots. I think but I am not sure the 800 and 1050hp MAN have the same cc engine with difference in turbo and valves etc.
