Several years ago I purchased a small "backyard built" airboat. It was a 14 foot alum. jon boat with a Chevy Corvair engine. It wasn't very fast but it was fun. I am now considering buying a larger airboat; 16-20 feet with a 350 or larger belt reduction Chevy. I would be using it in West Galveston Bay, Texas. The average water dept is between 4 and 12 feet. Also, during the summer there are many power boats (and their wake) in this bay. Is it a bad idea for me to consider using an airboat in this area unless I was satisfied with only running along the shoreline (to get shallow water and avoid the wake of power boats)? Any suggestions? Thanks.
