Recently purchased a Balboa 20' that has been in the water and neglected here in Tampa Bay for a while. Want/to get it on the hard for cleaning and to assess swing keel issues. Keel is stuck in the up position. Took a swim underneath, looks pretty rough. Have found couple of sources on swing keel repairs on the net, but not much luck on setting up a trailer for a sailboat. Have a trailer that is rated to carry the weight, but unsure how to set up the bunks for my boat. Is it just a matter of trial and error? Marina i am at now does not have a lift, only a ramp.
