I have a small 16.5 aluminum fishing boat with a 50 hp 4-stroke Mercury, and
the rig is a little stern heavy. The BassPro catalog lists the StingRays
from $50 to $120 depending on the model. The advertising says this will put
the boat up on plane easier and will cure the stern-heavy problems.

Does anyone have any experience with these hydrofoil products? Do they work
or would I just be spending my money on the advertising?
