Why do you want to lay mat? There would have been no structural component in the gel, if indeed it ever had any. Just scrub it all with TSP and repaint it. If you must have a fair surface, then fill and sand with epoxy after cleaning/sanding. But don't grind away the 'mesh'... that IS structural.

Gelcoat is just cosmetic. I'm not sure how much "bilge" a 17' boat really has but you probably will be fine if you apply two coats of antiskid deck paint (if this is an area you walk on) or two coats of white 2-part marine epoxy paint. (If this is really a covered over bilge area.)
