Continued bemusement over the years that in the lead up to racing Transpac (Vic-Maui, SHTP, Pac Cup, Honolulu Race) that a main speed detractor is ignored in seminars and prep. Out of sight, out of mind?
There is so much plastic crap, nets, and rope islands floating between the West Coast and Hawaii, that unless one's boat has a swept back leading edge on a full keel, a keel hung rudder, and hidden or aperture prop and shaft, you are 75% likely to snag unwanted debris on the race over, and 90% likely on the return.
This debris, at minimum, will slow you down. At maximum, it will cause safety issues, including compromise of steering and motoring ability, and the possibility of needing a potentially dangerous mid-ocean swim with a knife.
I could name dozens of boats that have had mid-ocean encounters with plastic. In 2011, the big 65' sloop ALASKA EAGLE got so entangled their engine was permanently put out of commission, and a diver could not disentangle the mess from around the keel and prop. Their sailing speed was cut in half, and the passage took several days longer than planned.
There is a partial solution that has been employed for years. Kelp windows. They have been in use for over 30 years on many Bill Lee boats, including all the SC-70's, and many SC-50's. One window sighting down the leading edge of the keel, one over the prop/strut, and one in front of the rudder.
Windows can be checked at night using a flashlite. Some enterprising owners installed remote cameras at their windows capable of being viewed at the nav. station. But you don't need that luxury or complexity.
Good news for the Dana 24, CARROLL E, you don't need windows.
Windows are not the total solution to snagging plastic. But at least you know what you got and can plan action. Barring a kelp cutter blade in the keel and rudder, the best thing to do when snagging plastic is to back down.
