Yep, boat is tied down here as well.

When I'm at a regatta venue that is not my homeport then sometimes I make sure that another F16 sailors places his trailer next to mine with enough spec between them to place both our boats. We then use the trapeze wires and the trailers to pin our boats to the trailers when the masts are stepped. We survived some good winds that way. And it removes the requirement to dig. Quick and effective.

But indeed F16's must never be left unattended or untied when their masts are stepped (or even the sails are hoisted). These boats are light enough to by thrown about even by modest gusts.

I learned my lesson as well, luckily no damage.

When I'm on a sail away to a neighbouring club to do some races there then I tip my boat over intentionally when I'm on the beach and getting a drink. I forgot to do that one time and a very modest gust flipped it when I was some 200 mtr away. The rig narrowly missed a pedestrian. Additionally I ALWAYS unhook my mainsail when I'm on the beach.

Again, these boats are just too light to take chances with.
