RedactedNarrative: Owner/operator was sailing with mainsail reefed and jib up.  Wind was off the land from N-NW @ 10-12 kts gusting to 25 kts.  Just as they cleared the point exiting Contention Cove heading east, they were hit with a very much stronger gust with a more westerly component, 30-35 kts.  operator tried to turn into wind to relieve the tipping but was not quick enough and capsized.  He immediately swam to the keel and hung onto it to right it.  His passenger was climbing back into the boat.  It righted and began to sail with him in it.  operator was to slow to catch the boat.  The gas tank of the kicker motor had washed out of the boat and was nearby but he could not get it.  He watched as passenger tried to gain control of the boat.  As passenger struggled, operator decided to swim for the north shore.  passenger sailed the boat close but could not come about as the jib had diconnected from the sheet and was useless.  operator swam to shore where a lady was gardening and he asked to use a phone and towel.  The Hancock SO arrived in about 5 minutes and he was trasported to MCMH in Ellsworth, were he was warmed up and then released.  passenger was unable to control the boat and ended up going aground on the Newbury Neck shore.  He was not injured and no damage to the boat.
