If the CG was offering to take them off by helo and abandon ship, they might have reasonably opted for waiting for a commercial tow. It was a brand new boat, this was apparently its first race, and presumably other than rudder loss they were OK, not taking on water. San Clemente Island is only about 50 miles off the coast. I read that the commercial boat did not launch due to sea conditions, presumably the skipper would have been notified of this, but it is still early so reporting has to be taken with a few grains of salt. Communications could have been a challenge. CG has VHF coverage out that far, not sure about Vessel Assist or any others. Poor skipper and rest of the crew probably second guessing themselves over that decision now.
