Thanks George, I don't disagree and I'm just re-discovering the fun of sailing upwind courses and still learning what works best.
We just completed another circuit of Tortola entirely under sail (though I did have to motor a few hundred feet through West End, mostly due to lack of patience).
I really think the 42 is a big improvement over the 40. I do remember the 50 sailed at least as well on the one 3-week trip where we were on one.
