There's a video doing the rounds in Finland of a new Finnish yacht being reviewed by a Swedish yachting site. The yacht is the Sailjet 40: a 38' yacht with a planing hull which can be driven at 20 knots by her 279hp engine:

Sorry that video's all in Swedish - I understand it no better than the rest of you, but still found it fun to watch. Here's the manufacturer's link: http://www.in-time-yachts.fi/index.php?option=com_content&view=article&id=2&Itemid=102

The yacht is on show at the Helsinki Boat show, which is happening this week. I got the following extra information from the salesman: she has a pivoting weighted centreboard; she has no water ballast system, but relies for stability on the weighted centreboard and the weight of her engine, batteries, fresh water and fuel tanks; when motoring you raise the rudder half-way so that it doesn't extend below the propellor; as the name implies the original plan was to have water-jet propulsion, but it required too many compromises on hull form for good sailing performance, so she has a conventional shaft-driven propellor.

The unusual rig was the choice of the first person to order one (they do offer a regular sloop rig): his priority was being able to get under low bridges. The 'schooner' rig with two furling genoas and no booms loses about 5-10 degrees of pointing compared to the sloop rig, and is obviously more trouble to tack: the owner tends to motor upwind anyway. The masts are carbon fibre and can easily be dropped by two men for going under still lower bridges.
 
Something similar was done years ago. I think it was called the MRCB. It had planning surfaces that came down at the stern. Not my cup of tea but still impressive.
 
Interesting, and not bad looking. But why cam cleats on genoa sheets? Massive load if you don't put enough turns on the winch and you'll have trouble releasing, surely a cleat or just self tailing is better?
