I am only new to windsurfing but I am totally hooked now, but I was wondering what is the advantage of using the underarm grip (front hand) on the boom? I see some people us it and some don't
Alternate to relieve muscles. Underhand better to pull down into boom for mastfoot pressure. I make sure I'm overhand grip as entering gybes though even though I then reach under with underhand grip to grab the other side.I generally sail overhand..
For normal sailing, it is a matter of personal preference. I use underhand only when the right hand is in front, but always change to overhand before gybing.
It's a good grip to have when going for the straps and harness. The pressure you can apply on the boom and mast foot acts like a 'killswitch' and prevent the catapualt.
Good to go underhand (and under the other arm) during the gybe as it helps to keep your centre of gravity low. You do need to change to overhand before initiating the next gybe though.
Personally I find the underarm grip uncomfortable for sailing, so I switch straight after gybing. I occasionally use it during a reach if my arm is getting tired.
I mostly sailing underhand grip, I find it's easier to keep front arm straight and locked in with rig away = more power and speed. Overhand for jybing and when wind is a bit on the light side..? Maybe to stay a bit more upright.? Not sure
I use under hand most of the time, except when doing any type of back wind moves like upwind 360, helitack, etc. I use underhand for jumping, gybing and wave riding. Go with what you feel comfortable with, there is no right or wrong IMO.
I use underhand but will switch to overhand to give the muscles a rest. I don't think it makes a great deal of difference, just do what you find most comfortable.
