Axis 1401! 1611 cm with 12.2 aspect ratio.
The foil is less than 1 year old. I have 150 sessions on the foil in everything from 0 feet to 10 foot faces, flat water, downwinding and winging. I weigh 83 kg.
The 1401 is my Goto foil when:
1) Waves are 0.5 to 4.5 feet
2) The wind is light aka 7 - 15 knots (no need for a sail bigger than 5 meters)
3) Downwinding in Short Period bump (ideally from 3 second period to 7 second period)
4) Low effort flat water paddle ups
5) I don't want to miss a takeoff in any of the above situations
I was regularly surfing 100% SOLO in the most populated corridor of the United States between New York and Boston.
During the month of June when combined with the 8' 8" x 19" board shown below I missed 5 takeoffs in 5 weeks (estimated 300 waves). I later added a silly short fuselage (560 mm) and a 40 skinny tail and the pumping was much further improved.
