Uttern S64, I have one with the merc1.7d, great boat fantastic economy and it also has a big 200l tank so filing up is almost rare ! I have just over 130 hours on it I bought it new from Essex boat yards, it had a few problems with water ingress to the cabin but I fixed it and Essex covered the cost of my time ect, good company to deal with. I use it to cruise around the west coast of Scotland ie. Jura, corryveckan,Colonsay, Ghia, Isla ect it has never let me down and it has come back in some serious sea conditions as my pals have 8.5 mtr Redbay ribs i tend to go out with them so anything goes ! I also have the lift up cover on mine which turns the rear of the boat in to a deck cabin when the weather is a bit wet, its only failing is the V of the hull could be deeper as it can give a hard ride in the rougher water, the cabin below has been great for the kids to sit in and watch their dvd when boredom sets in definetly a boat I would recommend to anyone.
