The inflatable keel in my Zodiac mkII is on its last legs and Ive been toying with a few ideas and was hoping for your input.
1) fill the existing keel with expanding foam
2) fill the existing keel with polystyrene balls ( like bean bag balls)
3) combine 1 and 2
4) build a solid keel like the ones used on the bombard.
Ive also thought about making the keel out of 4 seperate pieces and having them fixed to the bottom of the flooring
Has anyone tried these ideas and how did you get on
