If you anchor in hard rocks (not just gravel) then I think you will also NEED this type of product:

Call this guy at ezmarine and he has good info for you too. For Columbia River or Willamette River anchoring this type of anchoring system is a requirement.


If just gravel, like on the Skagit, then visit Holliday Market in Burlington and see their anchor "cannon" (anchor holder - fits on your boat - for convenience) that houses their "cylinder-with-feet-type" anchor that fits inside the anchor cannon.


We have BOTH of the setups I've mentioned, and have learned the hard way that we need both.

People DIE on the Columbia R. when they don't know how to anchor properly.....just ask the good folks at The Fishery (marina) below Bonneville...they've seen it happen too often.
