If you're buying new, then this is an expensive package considering it's just under 5m. Ribcraft fit Suzuki DF60 (109kg), but boat is rated for 75hp if you were likely to be hauling heavier loads, or using for diving. Agree with earlier post regards build. It wasn't that long ago that owners of other Ribcrafts noticed the forward anchor hatch didn't even have Sikaflex beading to stop water ingress.
Having said that I've found my boat (2010) to be well made. No hull or tube issues. If you opt for double jockey set-up, then space becomes a premium. Definitely opt for wear patches on tubes. Windscreen is nice, but not practical. Under-deck fuel tank would be nice, but not essential. The portable tanks (25 litres) fit under the jockey console, but only after Ribcraft fleece you for the GRP fitting trays. The double A frame is also expensive. You have been warned.
I use the boat in the North Sea and west coast Hebrides Atlantic. Been out in some fairly rough stuff, and have been impressed with sea-keeping. It doesn't slap and handles well with 2-3 up onboard.
The Rapide 750kg trailer isn't a patch on a Rollercoaster or DeGraff. It's too narrow and the boat sits high.
Without trying to throw a spanner into the works - what about looking at the Ribquest 4.8m?
