Tis the season for SailkotePlus, a day doesn't go by now that we aren't spraying McLube onto some sail. Spinnakers both old and new, from Manly Juniors (2 sqm) to 30 meter maxi yachts (450 sqm), the word is out there on the benefits of sailkotePlus.
If you are buying new sails, then have them sailkoted. If you race a centerboard boat, get the spinnaker sailkoted. If your mainsail furls in the mast, get it sailkoted.
Happy to discuss any application and describe the benefits.
In the meantime, checkout this cool video I just did of a sailkoted spinnaker going back into its sock.
