    I have a Towee Boats RiverMaster 16 (around 200 lbs.) with a Honda 15 on it. Frankly, it seems that I need "just a little bit more" to get the boat up on a nice plane. I see a lot of hydrofoils pictured on different boats & am wondering if they deliver definite performance improvements, or do you guys find (those that use them) that you have put them on and see not that much difference? I have looked at the Bass catalogue and they show a few that you can clamp on (I loath drilling holes in my gear) - are those worth anything> Any suggestions in this area, and "why" I see a lot of hydrofoils used, but manufacturers not putting them on in the basic design???

    It's an add on that compensates for improper loading
    and allows planing speeds at lower rpms, previous posts...

    The anti-ventilation plate is made from cast aluminum.
    Make it too wide and it begins to develop loads that will flex it.
    Over time that repeated flexing will result in the a-v plate snapping off.
    That's my thought as to why the outboard manufacturers
    don't make the a-v plates wider.

    It appears that even the foils can snap the a-v plate also. :eek:

    I put one on my SUV and it was like night and day difference - the boat fly's now. I used the one with the clamp that doesn't require drilling - the clamp also kinda reinforces the aluminum part it mounts to offering more strength imo.

    i put one on a 15 horse yamaha on my gheenoe lt25. i was looking to be able to run alittle bit more shallow.I used the one the bolts into the cavitation plate. I didnt really notice a lot of differance when getting on plane although there was nowhere near the same amount of bow rise so i guess that it did help alittle with getting on plane faster but i felt that it made the boat run a bit slower once wide open than without it. But it also made my boat run alot shallower. are they worth it.... not to me i took it off but try it out its the only way you'll find out for sure.
