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....
