In fair/ok condition.
Info appreciated.
More pics available.

No way to tell what it was without an up close look, but it's a double ended canoe that's had one ens whacked off and the sheer messed with when new rails likely went on. Looks like a Northland somewhat with that deck and circular marks on the ribs from a sanding disc. they were often glassed from new.
