Family friends had a 570 for quite a few years and spent a bit of time in it fishing mainly out of Moeraki, I always thought it was a nice ride compared to any of the alloy pontoons I've been in (mainly Stabis) maybe that flex was partly a benefit? It did move a bit of water in the front coming into a wave so could be a bit wet, they are nice and quiet at rest compared to alloy boats, quite low freeboard and a big following sea feels a little insecure but lots of alloy boats similar design. Good units the Haines, unbeatable ride, but if I was going to do a lot of drift fishing or fishing on anchor I'd definitely look at a more stable hull I've only ever been seasick a couple of times and both times in a bloody Haines! Lol
