That’s an amazing achievement.
I once piloted a 40 foot sailboat from Fisherman’s Wharf in San Francisco, across the bay, and maybe twenty miles up the Sacramento river. It was literally one of the most difficult things I have ever done in this life.
My dad berths at the Brisbane Marina and did the same trip you did. His wife got their boat stuck in the mud before they even got into the delta.
They had to pay a service to pull them out.
