Have you contacted anyone in the owners' association? They have one of the best ones around. You could check with other N22 owners there.
Have fun, they are great little boats.
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
