Richard,

You have a pretty good Hobie fleet in Mass Fleet 28 that can help you out. I would be more than happy to meet with you and your boat, but I just moved from Salem, MA to Annapolis, MD.

Try to get hold of someone in the Fleet 28 and have them go over your boat. Or, trailer it up to Fay's Boat Yard, the "local" Hobie dealer and they can go over it with you and get you all of the parts you need. I used them for years and they are very nice guys who know the boats.

I would need a better pic to see what exactly you have at the base of your mast. A shot up into the mast base would be helpful as well as a a shot of the mast step.

Good Luck
