Maintenance

Rinse entire boat with fresh water after each use. Be sure to flush all blocks and fittings
thoroughly.
Check the sails and trampoline for rips, tears, or loose stitching. Repair immediately to avoid
further damage.
Always keep trampoline lacing tight.
Tape all split rings and cotter pins to prevent loss or damage.
Check for broken or delaminated battens. Never sail with damaged battens.
Rinse sails with fresh water, make sure sails are dry and batten tension is released when
storing for more than a day.
Store sails dry, away from uv light and moist.
Always check beam bolts to ensure proper torque.
Check hulls for excessive wear on bottoms from beaching and dragging the boat. A bottom
job should be done to replace any lost fiberglass.
Check hulls for leaks at all hull fittings by covering suspected areas with soapy water and
blowing air (from your lungs) into the drain plug holes. DO NOT USE A VACUUM CLEANER
AS THE EXCESSIVE PRESSURE CAN DAMAGE THE HULLS. If the water bubbles, there is a
leak. Remove the fitting and/or cover with silicone sealant and replace. If the leak is from a
fiberglassed area (no fittings) this should be reglassed to insure proper permanent bonding
and sealing.
Check for water in the hull, take it out using a sponge. Little quantities can come from
humidity and temperature changes. Larger quantities could indicate a leak.
Check mast ball for wear- replace is necessary.
Masts should be regularly inspected for water tightness and diamond wire wear. Make sure
fittings are sealed with silicone. Replace wires that show any signs of wear. Check diamond
wire attachment points, turnbuckles and seizing wire. These areas could cause serious mast
failure and sail damage.
Avoid storing your Nacra for long periods of time with the rigging tensioned to race settings
( very tight.)
Periodically check for and replace frayed, worn, or kinked wires, shock cord, and lines.
Check all shackles, clevis pins, and fasteners for loosening or wear. Replace as needed.
Periodically check the bearings in the traveler car and replace them if necessary. Rinse
thoroughly with fresh water to free any stuck bearings.
