Danny, If it's any help, I'd buy another 40 in a heartbeat. Also the right 39, 37, 37+, or 41. Great boats all. That said, I wouldn't mind a more powerful engine in Peregrine, but I don't have the room for it or the fuel capacity to run it for long. Powering against wind and current down Vineyard Sound one gray day last summer, we were making 3 knots over the planet--sometimes less--until I hoisted a double reefed main and unrolled part of the jib and turned off the engine. Then we started romping along at 5+. And the boat felt better and we were happier. The nice thing about our boats is that they are so easily-driven that they don't need a ton of sail to make them go fast enough for cruising. And they are FUN to sail, which makes a longer passage easier to endure. the other side of that coin is that in the conditions you're talking about, even a boat with a good-sized engine is going to be considerably slowed by the chop.
