I've been windsurfing for about 35 years and foiling for about the last 7.
In case you haven't seen, I've got a
youtube.com/@Berowne channel with 100's of videos on foiling sessions, races, and a dozen instructional videos... so I know how to foil.
This year I decided to wing... but I wanted to get into it a little bit at a time.
The Cheap Approach
New Board - no need... I took my smallest 125L 75cm wide SB Foil Board and made it work.
New Foils - no need... originally, I started off just riding my biggest foil from my course racing days, with the shortest fuselage I could get.

The Wing - need... Can't use anything I had so I bought a 6m wing 2nd hand.

A couple of sessions in and I could get the board up and flying but minimum speed was quite high which made getting going harder than it needs to be, and gybes a challenge. But hey it was early days and only 2 or 3 sessions. If this is all I had, I could make it work. Except for the footstraps. They are way too far forward... but for a dedicated windurfer, it is possible.
Riding Backwards - use the damn straps! One of the strangest things... I tried riding back to the beach goofey/switch stance and it felt awful! After falling the 3rd time I sat on the board and thought about it. Why was riding backwards so hard, I windsurf both directions every damn day! So I tried the foot straps and my brain switched a gear, it made much more sense to my body and I made it work!
But!!! Because the front strap is so far forward and outboard I had to adapt and put my back foot well back and over the centreline, so I could maintain board trim. Some new ideas for board conversion below.
Using Dedicated Gear
New Foil - Of course I went with some F4 foils... and the new 1450 front wing is epic. Flies at 10kt easy and feels comfortable accelerating from barely more than walking speeds to flight mode. I need to get more confident before I push 20kts or try one of the smaller wings, but pretty pleased with the first run!
New Board - Yes Please. I have heard that dedicated foil boards can help... a bit narrower so they have better base speed and obviously with footstraps in the right spot will help a lot.
New Wings - Sure, I've only got a 6.0m at the moment, so looking at a 5.0 next.
I'm a long way from flying gybes, tacks or videos.... but hey it is fun to try something new and the setup - especially with F4 and an e-pump is so much quicker than racing windfoil gear! I can plug the pump into the wing, setup the foil, and I'm ready in minutes. Sweet.
It's easy to see why winging is growing so fast as a sport.
Easy setupI forgot my pump... which didn't have a guage and so I went off to the shop to buy one. ~$100 for a manual pump or ~$250 for a battery pump made more sense to me.
FootStrap plan... To help dual purpose riding, I'll try to find some of these footstraps and put them inboard at the rear most hole of the front foot position. It won't be on the centre line but should be a lot better than current situation.
