Recently purchased a 20' Koender Windmill and moved to out on the ice to one of my islands. In the spring I will upright it. My question is this, should I secure the legs in concrete or will 5' to 7' metal stakes be enough to hold the windmill upright during frequent high winds on my sand and gravel ground? Also, what your thoughts on extending the hose out up to 200' in the water away from the windmill. It comes with 100' of 1/2" hose moving a max. of 2 CFM, will 200' greatly reduce the already low CFM's? Thanks for your input.
