Its so easy to take masts down these days...why not do it?
I agree. Especially since putting down 4 proper anchors is more work than you might think and getting them back out is just as bad.
I know I'm paranoid about beach access. The thought of abandoned anchors causing complaints after the event is not very comforting.
Dropping the mast and securing to a "ballasted" trailer is the best option, IMO.
