Hello All.... I am looking at an Irwin 43' aft cockpit staysail ketch sailboat... with the idea to possibly purchase it... I was told by an exemployee of Irwin Yachts that they only made 3 of this model and interior makeup... this particular design was not offered beyond '77 .... it was not popular enough... for an aft cockpit it has 2 staterooms, 2 bathrooms, and a U shaped galley ... With the center board up it draws 4'-3", down 9' even... I have not found any layout for it online, but the exemployee was able to send me the layout design... it is a very comfortable looking sailboat and I would be happy with it.... what I am seeking is does anyone have any knowledge of the sailing characteristics ?... how well it points into the wind ?... how fast it sails ?... are there any known characteristic problems with this boat ?... are there any concerns with this model of sailboat ?.... I am awaiting any information... sincerely Jess
