I'll add that there is a bit of a
safety benefit to these
events in terms of "cruising in company"
offshore. First, there are a few cases of rally members assisting other boats in
distress. When you have 100+ boats following the same general
route you increase the odds of someone being close enough to assist with a breakdown, running out of
fuel, etc.
Second, the Coast Guard is paying far more attention to you. They come and do seminars and demonstrations and they follow the packs progress because if the weather gets bad they could be pretty busy.
If you've never done a long week plus
offshore passage these rallies are a great place to start. As far as
ARC vs Salty Dawg it's kinda a tossup. The former provides a much higher level of
service and support but you pay for the
privilege.
