Midseason Boat Maintenance Tips
Waterproof Canvas
A hot day, right after washing the boat, is the perfect time to rejuvenate the water repellency of your canvas by applying a product like Star brite Waterproofing with PTEF
Mask and Fins
While you’re at the sandbar or rafted with friends, dive overboard and inspect the boat’s bottom. Usually, the transom can stand a scrub to remove fouling, since not much “washing action” occurs there. Ditto for the scum line above the painted waterline. You may also have a layer of slime on your boat’s bottom. The trick is to remove the growth without removing too much bottom paint. We use a scrap of shag carpet with good results. It removes soft growth without scuffing off too much paint.
And while your down there, check out your prop for damage and look for line wound around the shaft growth, like barnacles, use a paint scraper with the corners filed round to prevent gouging.
Lights
Before buying a new fixture, clean the socket and contacts using 220-grit sandpaper wrapped around a stick. You can also purchase replacement sockets. If you do replace the fixture, consider upgrading to energy-saving LED lights
Air-Out
On a dry, windy day, open the hatches, pry off deck plates and let the boat breathe, to reduce moisture and the chance for corrosion and mildew.
Seacocks
Open and close seacocks regularly. Besides an annual disassembly and lubrication, constant use will keep them in shape and will alert you to problems before they become catastrophic.
Zincs
Check your zinc anodes for corrosion. While you may have been in the same slip for years without problems, you never know when your marina’s wiring or your neighbor’s boat has developed an electrical problem. If they have, it’s your problem too. Stray current can eat up underwater metals quickly. So make this check a part of your regular routine.
Lubrication
Lube grease fittings and linkages. Spray engine, fuse blocks and ground buses with products, like Corrosion Block or Boeshield T-9, that dry to a waxy film. Spray lubes that stay wet attract grit, making more of a mess.
