One of my friends who is originally from Taunton owns an 86 O'Day 272, not the LE though. I helped him sail it up from Marion to his mooring at the mouth of the Kicky in Mount Hope Bay several years ago. I tried emailing him and haven't received an answer as of yet. He's living in Tiverton and now has a mooring in the basin somewhere near the Tiverton YC.
You may just have to try and set the mast yourself. I kinow that it's not an easy task on this boat but not impossible with the right equipment.
Where are you planning on mooring your boat, on the Taunton River? I belong to a YC just down the road in North Dighton and we're always looking for new members.
