Jeff, I wonder if the boat your questioner is referring to is a Glibert 30? They were interesting-looking boats but did not sell very well as they were a bit pricey. The questioner also mentions 65* tacking angles. If this is 65* each side of the wind there is a definite problem. If it is 65* in total that would be highly impressive in a cruising boat.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
