I just talked to a San Fran snailbote racer the other day, one of his friends was on the boat. He thinks YES, they did cut too close to the island mark. My SF snailbote friend has sailed in the same race several times, so he knows what he is talking about.
The race committee bears responsibility for tracking race boats, with disqualification for cutting marks too close. Simple solution that should also prevent snailbote racers from using incoming freighter bows to cut off their racing buddies.
That happens ALL THE TIME in the Chesapeake Bay. This is the responsibility of the racing club to stop. Unless they adopt these policies, I support the USCG racing ban. Clearly, many racing snailbote skippers needlessly endanger the girlfriend/crews that happen to be on the boat.
If you are on a laser and have a death wish to sail too close to an island in stormy seas, or use incoming freighter bows to cut off your single handed racing buddies, you endanger only yourself and generate extra business for funeral directors. But, a big hassle for the families left over, the ship captains, and emergency crews tasked with dragging for your body.
Bringing a crew along is an entirely different situation, and endangering them is not right. Hopefully the racing committees will see the light and work with the USCG to adopt sensible rules to stop snailbote captains from needlessly endangering themselves and importantly, their crews.
In the article linked above, it seemed irresponsible that the skipper did not demand all his crew to "clip in" given those sea conditions, and not appropriate conditions to bring someone out for their "first ocean race."
