For a trip in January of 2017, there will be 3 couples plus skipper. Right now I am looking at 2016 40' Lagoon. Would that be a little tight for 6 adults plus skipper? 2 of 3 couples are newbies and have never been sailing on a trip like this. My wife and I are the 3rd couple and our only prior experience was on a Privilege 435. We were the only two with skipper on that boat so we had plenty of room obviously. Should I be looking at a bigger boat?
