I don't like the bow-I think Raisons is far superior.

Pacipat 650 and Pacipat Open 40

Found it: this company produces or will produce two designs. The pictures in post 104 show renderings of the Pacipat 40-much closer to the Raison concept. Below are pictures of the Pasipat 650-note the transom. The 650 was designed way before Raison's transat victory..... http://www.pacipat.com/

The renderings below show a Class 40 with very full sections forward but not quite what Raison did. But I'd imagine the key to Raisons success(like any scow) is movable ballast -and canting keels aren't legal in the 40's. So I don't see this design being anywhere near as successful as Raisons 747 scow.

I imagine it would be quite fast in any down wind race. It would have most of the advantages of the punt, but a slightly shorter heeled waterline. It would have enormous initial stability.

Unfortunately, it would have similar initial stability upside down.

It is kinda like Joshua Slocums 'Spray' gone on a severe diet, as it has what used to be called an 'apple bow'.

To make it 'self rescuing' would require strategically placed buoyancy tanks and flooding the hull, if it ever capsized.

I don't know if sail area is limited in 'class 40' design rules. This boat could carry an enormous rig and stay quite controllable even if pushed hard, especially if it were equipped with twin rudders.

- perhaps the weight of the movable keel would help righting the boat after a flip; it would already be high if it had been raised to windward if the boat was blown on its side, so it could be lowered under gravity in the event the mechanism was disabled by the knockdown. Maybe it could even be used to roll the boat all the way over if it turtled.
