I've not had worm gear, but have been on boats that had it, I really like it from a standpoint of strength and simplicity and easy on the arms! it should be easy for an auto pilot to control too. Personally I think gear drive ought to be used more often.... sure , not if racing
, but as a cruiser, I just want to point the boat in the direction I need to go adjust the sails
to that and not have to mess with it.
Great looking cruisiers! Both Cutters too... I'd go for the Westerbeke
(probably a perkins
4-108?) Those Volvo
MD2B's are great engines but very difficult to rebuild/work on I understand....
