Since several boat parts have weird names(wench, boom-vang, et) anyway, I had fun with a few more. The grab handles that are 180 degrees, I named the half nipple. The ones that are 90 degrees, the quarter nipple. On the second to last day of the trip, one of the ladies slipped and then told us how thankful she was that she was able to grab the quarter nipple to avoid a fall. We had a pretty good laugh. She eventually thought it was funny too.
