No boat is perfect, and in some cases it is possible to make significant improvements.
This gaff cutter was originally built with a centreboard, however in what is a surprisingly common alteration the board had been removed and the slot filled with concrete. The remaining underbody profile was far from ideal, and the boat was exhibiting handling characteristics that were detracting from her owners enjoyment.
The design of a new keel, and the insertion of a spacer to increase the draught aft has been extremely effective and the boat now behaves in a much more ladylike manner.
All commercial craft require a stability information booklet. This was an interesting case of a working multi role vessel with a crane.
