So how many of you ballsy people slapped one of those powerbox adapters like the NP glide/RRD WH onto your non foil boards ? Thinking about doing this to my 81cm wide 2017 135 Rocket Wide non-foil. Show yourselves so I may curse your names while my stern and foil sink to the bottom

Leash, correct washers, new stainless screws, tighten but don't overtight.
So, every newish powerbox board with the above things done right can handle it ?
Screw... singular. 
(Zeeko has a two screw powerbox alternative, though)
Just throwing an idea out, do you have a small powerbox board to try it on? Was watching some vids last night and saw a few smaller FSW style boards with the NP Glide wing. A narrow board (say 66-68) would put less side load on your box. Wide is typically better in the foil world but this may be an exception.

Bottom plate is a +.
Yup as long as the system has a big enough bottom plate I wouldn't hesitate, the risk is worth the reward. I have regular Tuttle box board with a PowerPlate it does a great job distributing the load, so far my board has been great and I'm well through the initial trial stages. I think there will always be some element of risk the first few times you go with a foil in a board not specifically designed for it. I've heard of a foil breaking a freestyle board in two, but the failure was between the front and back straps and not at the finbox, implying the board's overall construction was too light. In general I've heard more good stories than bad with boards that pre-date foil-reinforced boxes.
Good luck Dishpet!

Yeah, I don't know about using a freestyle board. Most of those boards you see on the used market are all falling apart. I can't imagine a freestyle boards holding up for very long as they are made of pixey dust
...hard smack downs would likely brake some part of a freestyle board, I know a guy breaking a freestyle board in between the straps aswell but from landing a big jump flat when windsurfing. I get nervous when my formula slaps down hard. But I have yet to see anyone on a freestyle board w/foil...maybe for good reason

So, a board that's meant to loop is made of pixie dust? That board that broke on the flat landing - I'm guessing wasn't the first time it was jumped or even landed flat.

Maybe try it in water not to deep so you can retrieve it if there's a failure until you get some confidence in it

Yes if the bottom plate is large enough, should be OK. I had an RRD WH with a good bottom plate, for 9 months and 40 + sessions on two un-reinforced boards, a 124 isonic and an old 147 ultrasonic, no problems. Sure it had a short Tuttle fitting, but much of the load seems to go on the front edge of the bottom plate. I didn't used to, but have taken to using a leash on my SB Race, after reading the doomsayers comments ?? on seabreeze. A flat webbing strap that goes under the rear screw washer and to a footstrap screw.
I think the NP power box fitting has a larger sized screw than normal. As the power box is a more wedge type fitting I guess you would need to be sure the plate is bearing properly on the underside of the board.

Thanks for the informative reply, how would you describe the difference between the sb and rrd foils ? A what about the width between the two starboards?

First it's probably not fair to compare the SB Race directly with the RRD WH. The SB Race costs twice as much. However, I think the RRD WH is a good foil especially for flat water. It flies slower (and lifts off a bit earlier) than the SB Race and is not as secure downwind in chop or swell, lacking stiffness in the fuse perhaps and the longer mast. Upwind it can point as high as the SB Race, but not as fast. There is a RRD WH foil review on windsurf.co.uk and if you sail lakes, rivers or off shore winds, and you need to fit it to any board the RRD is great. It even fits the 4 screws of a Naish Hover board. It is a front footed foil, so need those footstraps well forward. Seems to work best with medium, say 85cm width boards and mid size sails (6 to 7m) like in the RRD promo videos.
The NP Glide, I have only sailed with a guy who had one, he found the foil easier than the 2018 NP alloy but the 70cm mast a bit limiting. Obviously a less performance oriented foil than the RRD WH.
The isonic I used was 85cm wide and I needed to sail front foot forward of the footstrap downwind. The 2013 year ultrasonic is 93cm wide and foot straps were all good. Good luck.

This answers what I came to ask here. Yes, I understand its not a fair comparison, and just one more question, how much do you weigh ? I'm on the heavier side, 90+ kg so maybe best I start off with the glide seeing its large front wing ?
You may be better with a foil that has options for a large front wing. I'm 70kg so can get away with a smaller wing.
Maybe others have comments on NP Glide type foils? See the Naish thread on large wings. I heard Axis do a low speed wind foil with a large front wing. Axis are better known for kite and SUP foils.
For the glide foil send ?yvind a message on FB, he uses it with a relatively small board.
Wider boards aren't necessarily better for foiling, just depends on what you want to do, in the beginning a wider boards is easier to learn tho.
i'd never put a windfoil in a powerbox personally.
