Hi
I want to make a summary of the things I've seen on the net and make some comments about the comparison between windfoiling and wingfoiling. I've taken into account windfoiling can use big surf foils with small sails (WWF) and also small foils with formula boards and big sails. I want to highlight the last conclusion in bold below.
Marketing. Much more marketing in wingfoiling. Most of the videos are made in >25 knots. You can see how it's wingsurfing in light winds in this video:
. The wing is falling to water all the time. This doesn't happen in WWF windfoiling
Stuff size. Much smaller in wingfoiling than windfoiling, even there are 6?windfoiling boards
Rigging speed. Faster to assembly wingfoiling than windfoiling.
Risk. Much more risk for the sailor and the sail/wing in wingfoiling as the foil is not joint to the wing through the board
Performance. Different opinions in early flying with the same sail/wing and foil size. Better early flying with big sails and formula boards in windfoiling . Better upwind and speed performance for windfoiling in all cases
Shore break. Get into more difficult for windfoiling. Beach start and waterstart in small waves easier for windfoiling IMO
Easiness. Easier to learn windfoiling than wingfoiling as everything is joint. No disturbing leashes
Surfing. Small advantage for wingfoiling compared to WWF, but read this link
reefwarriors.wordpress.com/2019/12/10/wingy-dingy-thingy-vs-wwf-comparison/ and the former marketing point
Shlogging. Windfoiling can shlog when the wind falls better than wingfoiling
For a wavesailing windsurfer. WWF Windfoiling is perfect to increase the number of days in the water, using the same wave sails and even a big freewave board. I's easier to combine two similar sports
For a slalom windsurfer. Windfoiling is perfect to increase the number of days and reduce the size of the sails. They can use the same slalom board and sails. It's easier to combine two similar sports
For a surfer. I guess they would prefer wingfoiling or kitesurfing. The size of the board is more similar to surfing. They must buy everything new. They have to choose between having a foil or having a 30 m rope kite.
For a kitesurfer. Closer to wingfoiling but I think the wind range of kitesurfing is similar to wingfoiling. Kitesurfing is also good on surfing without foil. They must buy everything new. No clear reason to go wingfoiling except swapping 30 m ropes by a foil, shlog or try new things
For a supper. Normally they also belong to some of the former categories. Not always but possible to use the same supsurfing board for windfoiling. Impossible to use it for wingfoiling. Closer to windfoiling.
Conclusions:
Windsurfing+windfoiling covers all the wind ranges sharing some of the equipment. It's easier to combine two similar sports. The rest of the combinations need to double types of equipment and in case of change you have to rig everything from scratch. Windsurfing remains the best watersport for strong winds and waves
Windfoiling with big surf foils and small sails is almost as good in surfing as wingsurfing but has more performance (upwind, shlogging) and less risk
Unfortunately it's often more important the stuff size for the van than performance or any other reason.
Windfoiling could be the absolute winner if windsurfing industry had simplified the rig (like naish chopper sails), but instead of pushing WWF, most of the windsurfing brands are now making enormous marketing campaigns to sell wingboards and wings (except Goya and a few). They don't want to improve windsurfing, they want to make bussiness introducing as many new sports as possible to make us rethink everything and keep buying all the time. It's sad to have the enemy inside.
