[quote=DamonLinkous][quote=andrewscott]i like how the new Vipers outhaul works....[/quote]
It seems that all the modern boats use some form of that approach, where the main blocks pull directly on the main sail and not on the boom at all.
I looked at building a new lighter boom for my Hobie 18 using these updated principles but found that the new boats main clew was positioned directly above the main traveler track so the pull from the main blocks was straight down.
But on a Hobie 18 the foot of the main extends well behind the boat, so the blocks must pull on the boom, requiring a very beefy boom.
It's genius really, where sailboats have pretty much always connected the main blocks to the boom, connecting directly to the clew means you can use a tiny boom saving weight and maybe a sailors head.
