I'm about to finish up rebuilding my 1957 OT 50-pounder that came to me set up for sailing. The mast seat was mounted directly to the inwales, but had long bolts with the dowel spacers underneath the seat, apparently to give the option of dropping the seat, if desired. I like the lowered center of gravity by dropping the seat with spacers, but am concerned about the torque on it when sailing, if I do that. Did OT typically mount a mast seat directly to the inwales, or did they lower it with spacers as was done with standard seats? How typical was it for OT to use long bolts with the spacers under the seat? By the way, the build record for this canoe doesn't show sailing accessories, but they are definitely OT equipment. Perhaps this was all aftermarket and the owner just saved the dowels from the original seat.
