I have attached a picture of my boat with my home-made snuffer.

The opening or gate is out of carbon fibre. A kayak oar was cut up and fibreglassed in the right shape. The bag is light dacron. Goes under the tramp for about a foot.

Works really well with 2 lines for up and out.

The other alternative which works really well is fibreglassing an alloy hoop (available from Redhead Sails) to the pole. Very sturdy and light.
