I found our Lehman 12 'Cup Holder' on Craigslist for $500 it hull # 258 built in 1972.
As you can see, 'Cup Holder' is in dire need of restoration. Wood rails are cracked in places and will probably be replaced with a stronger foam glass composite. Newer version of the Lehman 12 have a wider gunnel that makes sitting on the edge more comfortable.
'Cup Holder' at the Alameda Sailing Association yard.
Haul the boat from Newport was a bit of an adventure with the 12' boat hanging 6' out the back of this rental truck.
