So, having just cruised on a relatively new Hanse 495, and then taken a tour of a new Bavaria 42 and new Dufour 46, I saw no travelers. The broker told me that powerful boom vangs are relied upon to close/open the leech of the mainsail. Indeed, on the Hanse the largest rope clutch and largest block at the mast pad serviced the vang. It was said that regarding cruising, a traveler would be needed only in light air; but with the powerful diesels now installed hardly anybody sails in light airs. What about it?
