Brian,
The boat is a 1962 Columbia. I am not sure if these spreaders are original or not.
They are made of wood, approximately 3.5 inches at the base and the wood part of the tip is approx. 3/4 of an inch with an aluminum band of about 1/8 inch thick going around the tip held in place to the spreader by two rivets going completely through the wood and band. It goes down the side of the spreader tip about 2 inches and has a notch on the tip that holds the wire in place. The notch is approx. 3/8 inch deep. These tips look like they were cut from a single piece of aluminum plate and shaped to fit the spreader tip nicely. Sorry for all the approximates as the spreader is at the boat and I at home. The base of the spreader has a vee shaped aluminum plate through bolted on each side by six machine screws and two holes that clevis pins went through to mount the base at the mast. The base fits into a channel that is welded perpendicular to the mast at a slight angle upward. There is no hole through the spreader tip for a lashing.
The boat has an 8 foot beam, 8000 lb Displacement
Please also see the thread before this one regarding possibly changing out the clevis pin attachment at the mast to bolts with nylok nuts?
Thanks.
