I am buying at an city auction a 25' 6" columbia, at this time I am the highest bidder. I have never owned a sailboat before and need assistance to determined what columbia I will be getting. It does not come with a trailer so I need to know if the keel comes off or stationary, If so what the depth so I can rig a trailer for transporting it home. I will have about 100 miles to transport. I have a partical Seria FLZN151A271, year 1971. It is going to need work but I feel I can handle it.
