Rigging question - What's this for?
 
1 Attachment(s)
Hi,

For a while, I've been wondering what the blocks on each side of my stern are for :)

I recently found this old brochure which shows them carrying a line through the back of the boom.

Is this simply to restrict the boom travel? Like a preventer? The advantage of this setup? Never seen it before.

Thanks.

My guess is that it keeps the boom from moving and banging around when the sails are down.

Too far aft for a preventer. So I agree with Calypso.

Thanks. I wonder why use expensive blocks for that. I currently just tie it to a cleat one side or the other of the cockpit to keep the boom static when sails are down. Seems a complicated solution for a simple problem!

I believe it's a double ended main sheet. The line goes from the cleat on the port side to the port block to the boom to the traveler to the boom to the starboard block to the starboard cleat.
This allows you to adjust the main sheet from either side of the cockpit.

FSMike's got it- It's a great system in theory, overcoming the free-floating traveller, and simplifying cockpit lines.

Thanks very much - I'll have a read up now I know what it is called! :)

If its not for the main sheets it could be block for the spinnaker sheets, that use the pads of the previous double ended main sheet.

I did wonder about a spinnaker (I don't have one).

A quick few searches on 'double ended main sheet', but I'm currently puzzled as to it's benefit.
