Having problems with message search?
There is a hole trhough my keel box however it is about 5cm above the waterline (and about 12mm Diameter).
However with this arrangement the hole is below the waterline when healed and the resulting constant waterfall into the boat is not good.
I intend to glassfible this hole up to ensure water integrity of the hull.
There is a gap between the back of the keel and the box that I was intending to fit a wedge and the rubber seems like a good idea.
I used to sail on a juno 560 - julian everit design, similar to e-boat and that had two large holes through the top of the keel box about 40mm in diameter and through these were two large metal cylinders.
through the middele of each of the cylinders was a tapped hole so a bolt couldbe threaded down to loch the keel in place.
I have attached a rough drawaing to show how this works.
I was contemplating installing a similer system but would have no idea if the glass fibre of the box construction would be strong enough.
Alternatvely if there were a way to use the existing hole yet make the system waterproof it would be a bonus.
Any suggestions or pictures of how your keel is locked down would be much appreciated.

Hi k9252y
I chaced with someone who used to have a saly micro: that had a bolt thro the keel box.
On my Gem there was a similar arrangement with a lump of rubber at the rear of the box as a shock absorber
