Block Arrangements for shrouds

Hindsite is always 20 20, I had designed a tunnel in the sketches, but manufacturing expedience ,weight and cost, combined to the fact we were never certain it would work, still not 100% as to what's going to happen in waves. It's a flat water flyer true enough but how she'll cope with the English Channel proper at a pace is yet to be determined.

OMG

Originally posted by JohnW As You have had ideas from the Merlins, I thought I would throw in the arrangement that I have on my Albacore, (you know you love them!  ) I have a single string that adjusts the jib halyard and both shrouds together to control rake, as well as the option to adjust each individually: Blocks with black centres are fixed, others are running.  The first stage of each cascade (at least) need to to be high tension blocks for example the ones on this page: http://www.pinbax.com/index.asp?selection=category&cg=7&mc=67&cct=4  To do the single string rake control, you need to know the velocity ratio of your shrouds to your jib/forestay so the strings move the correct amount and retain the tension - On my boat it is 1:2 (as near as) which makes it easy. Dont bother with muscle boxes (even if you can find them), too much friction for a given velocity ratio that a cascade.

nice one, but what does the green line do? i'm guessing it's shock cord.....

Ah, I see what's happening now. GRF: you have a nasty case of stringitis.

Its not an uncommon disease of dinghy sailors. Once you get attuned to the potential of using the strings to maniplate things, its quite easy to get seduced by this into have strings for everything, and then quite a lot more.

GRF, you'll just have to face it, you are becoming a dinghy sailor.

The one string jib/main thing has been done a lot of times. Its usually been abandoned too. I don't think adjusting main and jib together is the best way to get upwind.
