Rear sponsons mounted more forward

[Krenn Power Sports]

I have a trinity gen2 x2 hull... it's a -4 and the way it's designed I don't have any place to mount rear sponsons unless i mount them forward approx 16" forward of where they would normaly mount. Has anyone done or had to do this? if so does it work? going from regular sxr with tbm sponsons to this ski seems crazy, i have hardly any control at speeds and it slides out WAY too easy... I'd like a lil hook when I lay it over turning like my sxr....

Why cant you mount them at the back corner where they are suppose to be?

the bond line doesn't lip down it was cut off when made at trinity... the lip starts about 16" forward... basicly where they would mount to is non-existant

It's never going to turn like an SXR.

It's never going to turn like an SXR.

yes, i understand that... the bottom deck is an sxr tho, so it should have some characteristics of it.. i just need something lol..

Its -4. This is going to take away from the handling characteristics that an SXR has.
I would look at adding a TBM ride plate and grate.

i've installed a full length carbon plate already and scoop grate..

 

[Big Kahuna]

Full length carbon plate does not mean much. Is it a flat profile?

I don't mean this in a rude manner at all but did u really think it was gonna ride like a Sxr , 2 key reasons one its probably waay lighter and two it's -4 . Those two things are kind of a big deal at least to my knowledge

I did not expect it to turn like my sxr...... what I want/need is it to turn even a little lol.... The carbon plate is grooved not flat... and id like to keep it for weight purposes. Im guessing nobody really knows the answer about sponson position....

 

[Big Kahuna]

Look at the TBM with it double concave design it might actually help you turn. Most ride plates just help the Ski from porposing. The TBM helps with the handling..

Well to kind of answer ur question I wouldn't mount them way forward not really gonna help achieve what ur trying to get . Slap some front sponsons on her and drag some ribs . Jk if u think about it mounting them forward is pointless I would think you would want them as far back as possible to make ithem work effectively call trinity see there input

I tried, I emailed them about 2 months ago about it and never got a reply.... I know they are busy with the season, so i figured i'd see if anyone here had done it. i've seen the "x" wings on a few skis here, but I may just try making a set of sponsons and see how they perform... sometimes it's trial and error..

i had one on my sxr... the other issue with that plate is the amount of leverage it will have against the screws holding it... the rear are -4" and 4 more inches of plate stickout out... that's a huge amount of stress to put on those front screws holding the plate...
