Just decided since I get their magazine to check with them on insurance.

They are/were awful. The rate was 100% higher than what I have now.

For the life of me, why am I a member of this dreadful organization. They
don't seem to do anything for boating.

What are your opinions of Boat US?

They own West Marine, isn't that right? West Marine, in my area, sucks.
The store is in shambles. I went in two weeks ago to
purchase some paint. The paint aisle looked like hurricane Katrina had just
visited. Nothing was on the shelf, most of the stock was out or on order.
I asked one of the clerks and he said they were reorganizing.

A week later. I revisited. Same look, same mess, no products.

Are there other boating organizations which provide some benefit to their
members? Such as lower insurance?

In my humble opinion; Boat US is a SHAM.

My recommendation: don't do business with them.
