When I measured mine, the front adjuster added about 2" to the front stay when it was adjusted down to the lowest hole. You should be able to take that up by pulling down your shrouds to the middle hole or so.
I'm certainly no expert, but from what I've read the 14 sails better with a good bit of mast rake. Took this quote from an old post:
"Look online for the H14 tuning guide by former world champ Bob Curry.
This was also published in the Hobie Class Magazine (free on the internet, hardcopy if you're a Hobie Class member) called the Hobie Hotline... an article on tuning the H14.
The article discusses in detail: mast rake, rudder rake, forestay and shroud tension, mast rotation, downhaul, etc.
Oh yeah, the article is also on the beachcats website:http://www.thebeachcats.com/news/84/hob
Mast rake is good for going upwind, but moving the mast back moves the sail back, which puts more effort over the back of the boat, so that loads up the rudders w/weather helm. To counteract that, you bring the rudders in closer (mast back, rudders forward)... the rudders are adjusted to hang more under the hulls rather than behind. An inch here makes a lot of difference in helm feel."
I do have quite a bit of weather helm with mine raked the way it is, and I may shorten the front stay in the fall and add an adjuster so I can play with the rake a bit.
