Friend, it sounds like you're buying the Sabre 34, a fine boat that will provide your wife with a stable ride, until the winds blow 20+. Suggest you don't take her out in that weather right away. Or if you do, reef well and maybe fly just one sail. I find my boat does quite well with just the head sail deployed in a strong wind. Fastest I've ever had her was on a trip from Baltimore to Rock Hall, wind a whipping 20-30 and just the Genoa set... made it back in record time and hit 9.5 SOG as displayed on the GPS.
Keep us apprised, and good luck...MGM
