Pryde AL foil

I'm thinking they may get going a little earlier too with the new shape and slightly bigger size.

Does anyone use the NP AL Foil in an older style board without a reinforced foil ready tuttle box ?

Can it lead to breakage more than say the other foils which provide some support to the box even if not reinforced eg Slingshot, RRD etc on the Slingshot I understand that: it "...includes built in base flange to transfer loads beyond the box and more surface area of the board, not just the box. This feature is critical if you expect to use a foil with an existing board. A regular Tuttle box is not reinforced to handle the loads of the foil." The RRD includes a similar feature and the newer foils of some newer models from other brands are doing this. Does this mean the NP foils are more likely to cause damage to existing board without reinforced box ?

How does the NP AL Foil compare to the Fanatic Flow H9 Foil ? Which is rated better ?

Hi Richard, i use the NP AL Foil in my 2016 JP Slalom board which has a deep tuttle but isnt reinforced as far as i know. From what ive heard the lighter riders like myself (70kgs) dont have too many issues with the non re-inforced box but i think heavier riders may have some issues.

Hi Maddlad, Thanks for that invaluable advice and your experience which is in line with all the online research. I am 95 kg at the moment. I expect the AL Foil is not sturdy enough for me, noting issues others have had ( don't want to muck around with warranty claims) and I also like the idea of the lesser maintenance which carbon affords. Does the F4 "take off" earlier with bigger wing ?

No worries Rich. I have heard from guys who had the NP RS4 Carbon foil that it does get going a little earlier. I think it may be a little less stable when you're getting used to it though as it doesnt have the vertical stabiliser like the AL foil. Maybe someone who has used the Carbon F4 foils from Pryde can answer your query better. :)

Yes the Carbon NP F4 foil does foil up earlier than the AL. I think the Pinkie AL is a great foil for progressing on (I weigh around 88kg) and would comfortably foil up at 12 knots. With the F4 I can foil up at 10 knots and glide through 8 knots before re-connecting with a gust. Its not just the front wing thats the difference its the mast as well. AL is 85cm and F4 is 95cm. A light guy with good pumping technique could easily foil up on sub 10 knots with the F4.

Hi Richard

this is video I was using the JP 135 foil pro 215 x 86 @ 135 liters.

I have also used the F4 on a RRD slalom board 225 x 79 @ 122 and it performed very well in light winds.

Great vid mate. May I add how great JP and NP gear looks as well as performs.

CoreAs, That is a great video. Thanks. I guess you can carry bigger sails on the JP 135 Foil pro as compared to the RRD slalom board (w.79) with the foil since the wider tail and leverage off the width is more conducive in the JP135 Foil Pro (215 cm x 86 cm) ie you have the leverage to push it all around with a bigger sail in lighter wind. So on the RRD slalom, at 79 you would use say a 5.7 or 6 m2 max in light winds (freeriding) with the F4 foil. Hopefully you can more effectively ( or more easily) use a 7.2 or 7.8 max on the JP135 Foil Pro in lighter winds say sub 10 knots. I don't think, based on my research, that the RRD slalom at 79 would cut it in the lighter winds with, the bigger sails and the F4 but better off using smaller sails only above 10 -12 knots , on the RRD slalom with the F4 foil, that is to say, trying to run larger sails (say 7m2 and up) and pushing the foil harder upwind in light wind would require a wider board than the RRD slalom at 79. This is but one of the advantage(s) of the foil specific boards which work better with racy foils like the F4. Is that correct ? I guess this is even more so with the racier boards like the JP Foil Pro 155 soon to be 150 and the RRD H Fire Foil 150-(Antoine Albeaus vehicle) which would perform even better with the bigger sails facilitating even earlier take off. Cheers Richard

The above is the 2018 model and the new 2019 pro model is at top and below. Seems the new pro models from manufacturers for foil specific boards are limited to 150 litre max. and 91 cm maximum, due to rule changes at PWA level, influenced by what fits on the aeroplane since too wide is becoming too big to transport on airlines/airports. Also looking more JP or formula influenced than the 2018 models. Sorry this is getting away from the thread's theme. However the wider the board the bigger sail you can carry upwind railing the board down to windward like a foiling Moth Mach2. I have picked up a 2018 NP F4 carbon foil on sale, so now I am looking for a board. I think the JP135 foil pro is looking good but the RRD is of interest in the Wood version from 2018 H Fire based on the X fire light wind. I hope I can source one as that looks like a good all round light wind board that will be comfortable to sail with or without foil. I don't think you could go wrong with either however so should decide in the next few days.

Cheers Maddlad. I have switched this year to NP For light air foiling kit. 7.7, 6.7 V8 and 5.2, 5.7 hell cats. Combined with the correct mast it definitely helps with the pumping.

I do not think there is a rule of 150 litres. Starboard's 2019 foil board is 177L, and 2019 Fanatic is 169L. The width, correct, max 91cm.

Does anyone know if there is any difference between the Pryde AL foil fuselage length and the Pryde carbon F4 foil fuselage?

Madlad, the RSX foil is quite a bit different to the NP F4 SS Flight carbon foil.

Thanks Elmo, from what ive seen the RSX is pretty stable and good all round. I'm just looking for something thats a bit more stable and i'm getting the feeling that a longer fuselage (not too long obviously) will help. Its not that i cant use the AL foil coz i can, i just find i'm having to make more adjustments to keep it steady compared to others with longer fuselage foils. :)

2019 alflight

curved wings..... at last !!!

and a new model the "glide wind" with different head attachements (incl power box)

Yeah they're the ones i saw at the shop last week. I dont know if the wings on the AL Flight 2019 are further apart though to give more stability. It looks like a similar fuselage length.

Wow ! already released !!???

They don't seem to be further apart but the larger wings + curve should improve the stability quite a lot compared to the first edition !
