Ocean Anchor(s) - help

I am going to do a lot of ocean riding in the state of Maine and the Canadian border. Can anyone direct me via links to the best anchor/best anchoring scenarios for a waverunner on the ocean, when I want to walk ashore for a bit and explore?
I know this must be tougher than a lake for sure, however, I cannot tell which anchor(s) to BUY, as the descriptions on sites don't get to detailed of particular for me to figure it out.

I cannot beach it, as the tide goes out fast and not always a sandy spot.

Thank you in advance for helping this rookie!
