Yes........ change it over to a flat rail... you can order the hardware from Garhaurer Marine.
www.garhaurermarine.com With a curved rail you have to adjust the mainsheet whenever you move the traveller to maintain a constant twist in the mainsail. You should also consider running your traveler controls to a conveninent location near the wheel.
On my boat I tweek the traveller all the time, but I wouldn't if I had to leave the helm and go to the cabin top to mess with it. The idea is to set your twist for wind conditions and then play the traveller in the gusts to maintain heel angle. When tacking upwind you leave you mainsheet set and work the traveler as you make your turns.
With a curved track on the cabin top this is practically impossible without 2 or more people.
