Will a mushroom anchor work for a 34ft yacht? How much

depends.

Depends what the bottom is like, but in short, no. Weight isn't really the big thing, you really just want to be hooked into the ground, weight can help that. Danforth style anchors are great. For one they're really light, and secondly they dig in very well to mud. But not every bottom is mud. If you're in the Louisiana bayou, and there is a maze of Cypress trees below you, you're gonna get a Danforth stuck. In that case something like a mushroom or a cannon ball might be better so you don't have to cut anchor lines. I'm assuming that you're going in the ocean with a boat like that , if it's mud bottom (I don't really go near the ocean) go with Danforth, but if it's sand , I'd go with something a bit heavier, but will still hook. A navy style anchor will likely work well. As far as weight goes, I am not positive, but we used a 25 pound navy for a 28 foot Pontoon in calm water. (Lake calm not ocean calm). There's also something that works very well called "the claw". It's an odd shape but works very well. Two tips I have is to leave maybe 3-5 feet of chain between your rope and anchor, I find it holds better. Secondly a general rule is to multiply the depth of the water by seven and that number is how much rope to use, for example if you are 10 feet deep, take 70 feet of rope. This is something I read, and I don't really anchor in anything bigger than 3 foot waves. Hope I could help.

Jesus, I've been here too long. I thought that was a butt plug.

It could be. Nobody's gonna stop you from using it as one.
