So I am thinking of a pyramid shape form with granite and mortar/cement. Is 300lbs going to be enough for 20ft sail boat?
the boat will be in the Georgia straight so to exactly the wild pacific but we do get some gales. I will probably not have it out on really bad weather as I can trailer it out. the bottom is sandy unless I end up putting it on a rocky bottom.
I don't want to put anything plastic down there like a big 50gal bucket, but I am open to other ideas.
I don't think the screw idea is going to work so well as I am not a diver and I got quoted a huge rate, plus I might want to go where the bottom is rocky,
I get wild variances in weight needed, from the west marine article suggesting 10x boat length ( so for me 200lbs) to somewhere around 3000lbs from others (I won't be able to build an drop this safety)
