Jonathan and Jim,
Thank both very much. The frame looks much lighter than I would have thought.
I have spoken to a few people who have recommended not taking the keel right out. Unfortunately the trailer I have has a metal bar which the keel rests on so I can't drop it down to get the lower portion.
I am weighing up:
-frame to lift the keel
-heavy frame to lift the boat
-yard stand and pay for a telescopic loader each year to lift the boat
I am going to replace the keel lifting blocks with ball bearing ones to reduce the friction when I do the lifting eyes and line.
Thanks and I do look forward to hearing what others have done.
Danny
