Re: Non-skid worn down to fiberglass
Essentially what you would need to do is paint these areas with a suitable finish (eg Kiwi Grip?) or with paint with an anti-skid compound added. Fair bit of work, especially if there is much hardware to remove, but not a high-skill job or very costly.
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.
