Also a former 8.7 owner. I'm familiar with the 10.7, but never sailed one.
Based on the model year, I suspect it was one of the last 10.7s built by Columbia
before the molds and name were sold to a Canadian firm.
Beside the rigging (Columbia used aluminum
chainplates) check for any water
damage around the port lights and deck
fittings. If the engine
is the original Volvo
, expect a re-power is in the near future. The rudders on the 8.7 and the 9.6 were a weak point in the Columbia construction (not sure about the 10.7). The rudders were sheathed in very thin fiberglass
and many allowed water
into the foam-filled interior
causing the shell to crack during a hard freeze in the winter. Also the skeg where the gudgeon fitting for the rudder
is attached is hollow and can produce a hard to find leak. I filled the skeg on my 8.7 with epoxy
after it almost sank the boat. I think the 10.7 used a similar gudgeon and pintle attachment for the rudder
Those Alan Payne designed Columbias (8.3, 8.7, 9.6 and 10.7) were all good sailors, especially on a reach. The Columbia construction guality was not an industry leader, but most of the defects could be fixed by the owner or at modest cost.
