Thread: How do you make your underwater structure????

We just got our dock on smith lake installed and it's in about 20-30 feet of water. What is your advice for the best type of structure to sink??

I was thinkin PVC structure because it last longer and you don't get as easily hung up on it, but also read some articles about how PVC isn't that great. With there not being too much structure on smith lake, it being a very deep lake and all the docks being floating docks, i figure something is better than nothing.

Any help and advice would be greatly appreciated!

I was thinking of something like the attached pics.
