...and no one really knows. I used them as hand-holds, bungee attachment points, and a convenient place to put the empty beer cans (on their side) until I could properly crush them and chuck 'em in a trash can. They also hold tubes of sunblock or bug spray pretty well... Winch handles will fall out of them though (as the small chip in the cockpit floor will attest to). They'll hold sail ties, wet towels or clothing, and were a great way to hold the sawhorse I used for a mast crutch... There was another thread started in October of 1999, titled 'Whatizit', that asked the same question. Apparently, according to Hunter, they serve no real functional purpose.--Jon BastienH25 'Adagio'
