Rope Self Tackers

   If the track is underbent (ie closer to straight) the car will be pulled towards the centre when you yank on the sheet tension.
If the track is overbent the sheet may have to be eased for tacks as sheet tension will pull the car towards the outside of the track.

Idealy I think the track is supposed to the slightly underbent... but straight is definantly a bad idea

	I've seen boats with both curved tracks (keepin the jib under tension throughout) and some with apparent straight ones, do they all work as good as each other and if not what are the benefits or problems with the different setups?

	Ronstan sell curved 49er and 29er tracks/cars. Atum Bom ( which is the current 2 x uk nat champ cherub) has a 49er track. Sometimes ronstan have undrilled track in stock that you can get rolled to the bend.

	You'll need to get a skilled metal basher to bend you one. You should get undrilled track - getting track with predrilled holes in bent will rarely give good results.

	A W track is one where there is a reverse curve in the centre rather than being a continuous radius. The sheet gos slack as it goes past the reverse curve. It enables the track to be a bit further aft.

	One of the 3000 class has been experimenting with self tackers to go with the big and roachy, overlapping North jibs. A W track was tried but the sail didn't reliably cross the boat. The continuous curve Mk2 track is reportedly much better. The too-far-forward jib cleat that results from the continuous curve is compensated by use of a clew board on the jib. Ie it's sheeted from slightly in front of the clew with the board providing tension in the roach. I have yet to see it in use mind .
