Re: Is a Vang Really Useful on a mid to Large Boat?
just reading the last few paragraphs here and comments makes me realize that maybe not all of us here have had experience sailing dinghies and small boats...
you really learn so much I recomend it to everyone
vangs arent for preventing gybes...
vangs on small boats, dinghies, racing boats and the like are designed for better sail shape...
you get a bend in a boom and you flatten sail if really windy or get a little pocket if light air...this is paired with outhaul tension and downhaul enabling you to get a better shape and more wind...or less depending on what reach you are.
in laser sailing for example as soon as you round the number 3 marker and head ddw first thing you do is dump release the vang...and outhaul....if your quick you do it all at once...while getting the boat flat or the main up in the air to get cleaner air
(you cant do this on big boats really but just sayin)
that way you get a nice big bellowy sail to fill up with wind and you fill it better and sail better...
now applying this to big boats is hard sometimes...first off its hard to get the sail all billowy and full of air downwind cause most boats especially cruising boats have all sorts of crap, reef lines, winches, lazy jacks, running backstays I mean a whole crap load of stuff on or around the boom and sometomes the outhauls dont even work or are frozen if the sail is rope rigged into the boom etc...
now not all sailboats or cruising boats are setup up this way but I know of very very few big sail boats and captains that would do this each gybe or heading change
I was friends with some guys on an esprit 37 who tuned that boat like a race boat, rod rigging, masive vang, 2 spinnies...and they flew an asymetrical all across the pacific days on end...they were FAST
again I stress vangs do help preventing the boom from going AWOL or like the scenario mentioned above, this happens a lot in laser sailing if you let out the main sheet too much and the boom is forward of the mast downwind...that is not to say its main function is to prevent gybes thats not true
Islander 36 no longer for sale...its MINE!
