Hull "136" 21 Classic -Found

[Islandtrader]

Maybe Carla can help us out.
However I think they gave out numbers for each hull length, and did not run them across the different lengths.

My boat is registered as a 1970. However we believe it was built in 1966 or so.

The explanation for this, is in the old days the boat was assigned a year when it was registered and not when built. The boat could of been sold used for a few years and then got registered. Back in the 60's a lot of states did not have mandatory registration.

Your tug is quite the machine. Nice work.
