1957 duo glass lake n sea U-15 model, very rare boat and is totally retro. I have had it in the water last year, but have 5 boats and it is just not getting enough lake time, so it is up for auction. It has a 50 hp twin cylinder 1975  evinrude and it runs great, upgraded teledyne steering with the single cable, and the newer evinrude power pilot controls. It is a good boat to cruze around in and the transom is still in good shape it was rebuilt about 10 years ago,, and the boat planes off quick. I have fold up seats and a cover and spare tank that goes with it. Its paint is faded but could be resprayed, and some paint inside, but it is all cosmetic. The trailer has new bearings, seals springs, tires, paint and can go anywhere right now no issues, ball is 17/8. Like I said got 5 boats, this one i inherited from my uncle, it is fun, but i have a 20 ft citation lazer with a 400hp smallblock  he gave me too, so that one gets most of the summertime runs. In any case it is a cool vintage boat that needs some tlc, but not much, motor has been gone through by pugsleys marine and runs like the wind, also a new prop.the fins are real cool, it would be a great one to restore to day one. In any case thanks for looking and happy ebaying!
