1) Use Gloves
I love the spinnaker: when you put it up you get this surge of power as the boat accelerates - hopefully in the right direction.
But it can be a scary sail. The thing is it just has such a huge area that the loads on it can be hard to manage, and it needs a lot of ropes, which can lead to all sorts of tangles.
This story however involves a hoist of the spinnaker in the picture above that went wrong. The man swigging on the halyard by the mast didn't notice that the rope wasn't being pulled through the jammer but was coiling at his feet. So when the wind caught the sail the rope went flying upwards through his hands, and he wasn't wearing gloves.
The result was not pretty.
2) Stay in the boat
A couple were once found swimming half way between the islands of St Lucia and Martinique. They were all on their own, without a boat and also without any clothes.
Apparently they had been out sailing but as alas happens too often there was no wind. So they decided to go skinny dipping, both of them.
However once in the water the wind picked up, and it was fair to say they were lucky to be picked up too.
Lets be careful out there.
