Hammocks

[Talbot]

Under the boom on a cat (normally high enough for that!)
on the spinaker line or on the topping lift (with another rope to keep the line away from the mast).

[Bill Roosa]

Looks like it could double as a dandy bosin's chair too.

[LaLeLu]

We hang ours between the mast and the forestay. Your C 27 should be able to take the weight - the pounds on your mast/rigging in a good wind is much greater than your weight. As for knots, just remember, if you can't tie a knot - tie a lot.

[Canibul]

just gotta know the difference between a should-knot, a might-knot, and a will-knot....
