Easy way to put in brushpiles without messing up your boat. I cut 2 holes in the buckets and run pvc through the buckets. Place big limbs and bamboo in the bucket then pour cement about 6-8 inchs thick. Here is the best part. Cut a 6-8ft bamboo pole for each bucket. These are easy to put in the bed of your truck and deck of your boat. Once you get to where you want to place one, push a bamboo pole in the water to where it is sticking out the water about 2-3ft. Drop the bucket sideways down the pole. Then i made a sleeved pole to push the bamboo pole down and out of sight on low tide. I've been doing this for a while. They last a long time and will never wash away.
