Ribcraft 4.8 commercial. Rated for 75hp, but 60hp seems to be well suited.
Had mine since 2010 and it does everything I ask of it, whether North Sea rough chop or Atlantic swells. Also right size if your single handed launching and retrieving, but be warned, this is not a light boat.
£6,500 might be lower end of budget for a decent example, but hypalon tubes are well made. plus you can customise with genuine Ribcraft A-frame, wing-back jockey seats and flow-coat the deck.
Be prepared to travel when one comes up.
