Kiteboarding/Kitsurfing Self-Launch Sand Anchor

very well made but I feel that it should hold a bit more sand. I used this to self launch my 13 meter kite in approximately 20 miles per hour of wind and the anchor started sliding down the beach. fortunately it slid slowly enough that the kite did not get away from me. I weigh 165 pounds and was riding powered out on the water but I feel that this should have been built a bit bigger to hold more sand.

I think it's a great product, and watching the product review at kiteboarding.com it's clear you have to BURRY the triangle in a bit of a sand hole, then it's the EDGES of the hole that help the bag not move in the sand, for any size kite. (same principle is often used to stake tends in sand or pebbles. Don't just COVER. Must dig a little hole first.

All good thanks
