In response to Kings Gambit, the traveler right in front of the helm makes mainsail adjustment very convenient for the helmsperson. On the boat I sailed, however, the main sheet MA got tangled in the SS tube hand hold at the binnacle and nearly ripped it off (when exposed to a huge gust at the Potomic River which almost knocked the boat down). It was an add on, I think, to protect the GPS chart plotter, but her forward attitude got in the way and so had to be changed. When the owner bought the boat new, the chart plotter was in the basement at the nav station and not at the helm, which is where I prefer it. It was Ray Marine and there was no such thing as a repeater, so he had to buy another unit and one became the master and the other not so, but could be adjusted at the helm for important data while navigating from the cockpit. Very expensive upgrade, indeed, but since I did much of the navigation and driving, l liked it at the helm. I just would've picked Garmin as my choice as you constantly had to tear into the manual to figure out how to deal with the unit and Garmin is so intuitive you don't need a manual. Am I digressing? So sorry.
