What model of boat did you get?.I had a look at a few of the older 5m fiberglass boats a few weeks back, there are a few nice looking Sea Nymphs and older Haines Hunter’s on the market, they are suppose to be a highly seaworthy design, but I could never bring myself to trust the old engines on most of them, and a re-power would stretch my budget.
Thinking of getting a 5m Aluminum pontoon myself. Mainly for the lighting towing weight and less fuel thirsty. Having one would make accessing several good spring time Snapper and Kingfish spots much easier. Although a boat is of limited use during Summer and autumn when the fish are all in shallow.
