Reminds me of a story in CW a couple of years ago. Long story short: 2 brothers with no sailing experience left S.
Cal for
Hawaii. Made it. Bought a new handheld
GPS - floating model. Sometime afterwards, they were sailing, had an unexpected gybe.
GPS fell off
cabin top, over the side. One brother dove for it - and thought as he hit the
water, was THAT my brother
diving over the side too? Luckily, they were near an island, swam to shore.
Boat ended up on a reef miles away, and they got it back.
