My Gosling Sail no 4756 has large blisters inside the centreboard case which restrict its movement (see photo). There are more blisters further down which will be challenging to access.
I figure I'm going to have to carry out something akin to an osmosis repair on a hull this winter.
Has anyone else experienced this with a centreboard case?
Thanks in anticipation
Nick

I understand the glass Goslings are moulded by a third party and completed at Goslings. But Kevin is a superb craftsman and I suspect would be a useful source of advice.
But of course he can't control what earlier owners may have done
