Haven't been in one but have looked at them and they appear to be of good build quality at an excellent price

Had one for 5 years amongst 6 other boats over a period of 15 years. Definitely, the best hunting machine I ever had. Dry, fast and soft riding. It is built  and designed very well for fishos with all important aspects present where it matters eg. side pockets strong to stand on and anchor your feet in whilst fishing in rough water, high freeboard, uncluttered deck, good access to raised battery shelves, huge cabin hatchdoor that can accommodate even a hefty guy, good size cabin for overnighting, solid keel to absorb wave impact and not being overbuilt in areas of unimportance resulting in unnessary weight. Soft area is that ,it is a bit tender on the stability side when it is stationary but no big deal. Boat is, in my opinion, a two passenger around 200 kgs leaving reserve bouyancy for offshore use. I will certainly return to a 555 if have to downsize in the future. Hope this helps you.
