I've had a few cats in my life, and all have had crappy traveller systems in my opinion. It is dead difficult to use the traveller to best effect with the systems that come with Hobies, Prindles and Nacras. Granted, I have only had older boats, so maybe on the later boats these systems are improved.

To use the mainsheet to tension the main and the traveller to set the angle of the main I want to be able to have better control of the traveller than the traveller sheet anchored at the middle of the rear beam, then passing through the block on top of the car, and then to my hand. This is effectively a 1:1 system when the traveller is dead center and a 2:1 system when it is eased out. Mostly it is close to center.

What's a better solution?

I am putting together a P18-2 and would like to get it right.

Thanks
