Spitfire vs Progression for pumping in the surf

Prone Surf Foiling
21

One important note… I was comparing the 170p pump to the art1099. The Axis 899 was terrible for me. 1099 pumped well. I should’ve been more specific with my earlier comment :call_me_hand:t3:

Interesting, what tail do you find works best with the spitfire? Alternatives are skinny, p375, og 333. Would you shim them for less pitchy?

Nice, yeah the 1099 in glass was very fun, 899 just hateful for me too.

Hey Matt, also an 880 rider considering the 900… would you say the pump between SF 900 and HPS 880 is equivalent or could I get away with the 840 @75kg? I can link 3-4 waves max on the 880 just want the roll and tip breach the spitfire provides ( and am too deep in axis to warrant jumping ship!

25

Didn’t ride the Spitfire. All I’m saying is that the 300p is a small tail, that made every setup pitchy for me. I still like it for dock start but overall Axis allows you to create those mutant setups with extremely small fuse and tails which

I’d try demo them it has been ages since I rode the 880 and don’t plan on riding it again so more likely the progression140/spitfire900 is a more valid comparison point. I’m 70kg and felt like I could prob get 3 or 4 quick links without blowing up. The HPS needed to be going really fast to get any efficiency in the pump so I would imagine you could size down

nice comparison Matt - it would be really great to get you onto the 877 or 1107 for comparison also as they were designed for similar usage, namely to pump, glide and turn well, without sacrificing too much top end, so on paper should be right between the Spitfires and Progressions.
They have custom sections optimised for high lift without stalling but also with a low drag through most of the range. Top end is similar to ART but much better low end and pumping. It would be possible to gain even more low speed lift but you start to pay fairly heavily in drag at normal foiling speeds…
Planform is reasonably high aspect ratio for the glide, but not extreme for the turns, and tips are designed to breach easily without venting.

Hey Mark yeah thanks for following up, would be really interested in having a go, especially to compare with the progression, as they are maybe more similar in design than the Spitfire. Maybe a session in Cornwall? Buddy here is riding the 1201 very extensively so would happily give you feedback on your 1107 too.

What’s the AR and area on the 877 and 977?

30

They are pretty close dimensions as below, however are very different foils.
977 is more of a race foil, high top end but relatively higher stall speed.
877 has a much lower stall speed so will get going much earlier and keep gliding for longer, but doesn’t have the same top speed.
877 is 877cm^2 / 910mm span / AR 9.4
977 is 977cm^2 / 950mm span / AR 9.2.

I have been riding the Spitfire with KD Marlin 14" tail. I tried it on a 325P and it felt draggy and not fun. The Marlin for me is perfect for my 900 Spitty. Perfect balance of pump, glide and super loose. The more I ride the spitty, the better the pumping gets. I would love to try a Progression someday. Someone please send me one. Thanks!

What’s your weight? Trying to decide between the 900 or 840 @72 kgs… can pump the hps880 3/4 fo

840 for sure. I’m 76kg, and can pump the 840 pretty easily, and find the 840 slightly bigger then ideal (but still fine) for me in the surf in waist to chest high waves.

Wondering where the old lift ha wings fit into this equation? It’s obviously a better surf wing than art. And it will pump better but turn worse than spitfire. Is progression a better version of lift ha? Or does lift ha still have their place in today’s wing landscape?

A “big difference” is subjective. For me, I can pump the 170p easier that the 200ha. I would say that I can flat water pump the 170p about 10-15 seconds longer than the 200ha. Surf performance on 170p will be much better that 200ha

Does the KD Marlin fit for Axis? Top Mount?

38

I bought a KD Marlin made for Axis but I spoke to Kane at the Gorge and he said that it was only a limited amount that he made because the Axis skinnies just dropped and they were similar. It is a top mount. Just ask him if you can get one. It is the most versatile tail I have had. Haven’t tried the skinny’s only because I have the holy grail already.

thanks, good to know, will hit up KDM and ask if he has any left overs

I recently switched from the HPS 980 to the spitfire 960. The spitfire is easier to pump but has a higher stall speed. The spitfire drops abruptly unlike the HPS which gave me plenty of opportunities to grave dig. But for whatever reason I’m less gassed after pumping out to a second wave on the spitfire than on the hps.

I wonder how the Spitfire 1030 and the Progression 200 compare for pumping and linking knee high slow waves on a sup for a not so very fit 67 yo 85 kg
They are very similar in dimensions:
Spitfire 1030 Span 1030 Surface 1308 AR 8,26
Progression 200 Span 1037 Surface 1290 AR 8,30
Which one is easier for a not very talented pumper?
Which one has a lower stall speed?
And which one will be more fun?
And what tails would make pumping easier on both of them?
And what about the Katana and Progression mast? 80 cm is a bit long for for small waves breaking on a shallow sand bank…

didn’t try a spitfire but I can rock-start the 170 progression, it glides and generates lift in slow speed, plus very pumpable. so probably the 200 progression will be easier to pump and connect waves than spitfire, but as I mentioned, didn’t try one.
14.5 progression tail and 75cm mast will work well for your scenario
