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.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
