Harken Hardware
The I-20 is fitted with a pair of elevated, radiused Harken travelers, for the main and jib sheets. This particular main traveler is the 'water-cooled' specification, to get the windward sheeting traveler car up above the bumps and wiggles that are the deck laminate.
Jib traveler detail. That screw shackle for the jib clew is a 'captive pin' type. Almost impossible for ham-handed crews to drop the pin overboard. All of the shackles on the I-20 are this style.
