They came out around '91 and were dropped around '96.
Medium V hull, so a bit of a handful in the rough, climbing over waves, rather than cutting through. They had a moulded GRP deck with inset fixings offering various seating/console options. Jockey console was ok, but most opted for the 'leisure' (med style) layout with an offset steering console and full width bench seat aft. This gave loads of open deck space, but made the boat very stern heavy and they'd struggle to plane with a couple of heavyweights on the bench (don't ask
Avon also made the D4.65 diveboat version of the same hull, in rescue orange, which had a plywood deck and could take a bit more abuse. These came as open or centre console spec.
Personally, I don't like them - 4.7 Searider is a much better boat, but has a narrower flat deck on account of its deep V hull.
