The Albin express trawler is a neat boat. It would work well for a couple and maybe a small child or two. The interior is a little small bit you are rewarded with an excellent layout topside...which is why we boat. Are you looking for speed??? The particular boat you are looking at has a single Cummins 450hp. Which is a good engine and it appears to be well maintained. But, you may be able to cruise in the low teens and that would be about it. If that doesn't bother you, then cool. I do believe that boat is a bit high priced for the single engine version. But again, it does appear to be well kept. That boat has been on the market for about 6-8 months with no price reduction. Anyway....I was in that market so that is why I know.
If you are interested in that boat, the Mainship 350/390 was the direct competitor to that boat. It is even less likely to be powered to cruise at planing speeds....if that is what you are looking for. But in comparison, I think the Albin is a slightly better built boat. The Albin has a better exterior layout and the Mainship appears roomier inside. Some of the newer Generation Mainships(2004 and newer) are starting to get into that price range.
If you want speed in a trawler then your choices get very narrow...and expensive!
