Hi all!
With earlier keel ram probs fixed and 'Nautibouy' out of the water on Saturday I now need to consider setting the keel retention pin position.

Normal mooring is about 15 inch mud on shingle. Tide out she leans to port mostly when at rest and the pin has been wearing the GRP of plate case into a 1.5+ inch slot on starboard side and about 1 inch on port side.ie slope down to port. Since at mooring prevailing wind is SW and tide out runs South I guess the wear is on downhill side of gentle slope East to West of mooring area.
Highest part of bulb is about 5inch under hull.

I have had made up two x 4 in square stainless plates with horizontally welded in tube sections to take the pin.
These will be screwed and bonded in position after 'slots'are repaired. However on Port side of casing, cut out for replacement keel box with stainless one was done rather over enthusiastically and includes the pin position. I will glass this back in securely ( it had come adrift and was patched upto last to end of season).

I seek your advise / comments on :
How high can the keel be set bearing in mind raising keel position raises the CG?
Is there any other reason not to raise it until stopped by keelbox touching U/S of top level in housing? This should reduce heel angle at low tide and perhaps reduce side loads on pin.

Cheers

Paul
