We found ourselves in the same situation as yourself a couple of years ago. Our initial thought was the HR 34 as it would be easier to handle, cheaper on moorings,sails, antifouling etc. Then we had a look on a 34 and found that my husband, who is 6ft 2in tall, couldn't use the heads due to lack of headroom and we settled for the HR36. He is very comfortable on board, both below decks and in the cockpit where the boom clears his head whilst standing at the wheel.
Do you have any preference regarding saildrive, HR34, or conventional shaft drive, HR36,?
