Honest answer: if you're an average-sized adult learning to wing foil in Ireland, buy a 5m first. For most riders between roughly 70 and 90kg, a 5m wing is the size that gets you going in the wind we actually get on the west coast, and it stays useful long after you're flying. If you're lighter than about 65kg, a 4m is the better first wing. If you're over 95kg, start at 5.5m or 6m. That's the short version — but the reason matters more than the number, so here's the rest of it.
Wing size is really about wind, not about you
A wing is a sail you hold in your hands. Bigger wing, more power in less wind. Smaller wing, less power but far more control when it's honking. Your body weight sets the starting point, and then the wind you ride in decides everything else.
Rough guide, assuming a beginner-friendly big foil underneath:
- Under 65kg: 4m as your first wing, 3m as your second.
- 65–80kg: 5m first, then a 4m for the windy days.
- 80–95kg: 5m or 5.5m first, then 4.3m.
- 95kg+: 6m first, then 5m.
Notice that the second wing is always a step down, not a step up. Almost nobody in Ireland buys a bigger wing as their second purchase. Once you can foil, you'll ride in more wind, not less.
What Irish wind actually looks like
We teach at Rusheen Bay and we're in and out of Galway Bay year-round, so here's the honest picture. A good learning day here is 15 to 20 knots. Below 12 knots you'll struggle unless you're on a big light-wind setup. Above 25 knots you shouldn't be learning at all — you should be watching, having a coffee, and going out tomorrow.
The useful thing about that is it makes sizing simple. If your first wing covers 15 to 22 knots comfortably, it covers most of the days you'll actually be allowed on the water as a beginner. A 5m does that for an average adult. A 4m only covers the top half of that range, which means half your good learning days get wasted standing on the beach.
This is the single most common sizing mistake we see: people buy small because small looks fast and manageable in the shop. Then they can't get flying, decide wing foiling is hard, and the gear sits in a shed. Get the size that gets you flying.
Which wings we'd put you on
We stock a fair few, and you can see everything on the wings and parawings collection, but two cover most first-time buyers.
The Ozone Fly is our standard recommendation for a first wing. It runs from 2m all the way to 7m, it's forgiving, it sits quietly overhead when you're getting on the board, and it doesn't punish you for scruffy technique. The 5m is the one that leaves the shop most often.
The Ozone Flux V2 is the step up — more direct, more drive, more range per size — and it's what a lot of our riders end up on once they're linking transitions. It comes in 2.4m through 6m, so a 5m Flux and a 4m Flux is a genuinely complete two-wing quiver for an Irish rider.
If you're the kind of person who'd rather be out in 10 knots than not out at all, that's a different conversation and usually points at a light-wind-specific wing and a much bigger front wing. Come talk to us before you spend money on that one.
The size on the wing isn't the whole story
Two 5m wings from different brands, or from different years, can feel like different sizes entirely. Aspect ratio, stiffness, handle position and canopy material all change how much usable power you actually get. A stiff, high-aspect 5m can feel like a soft 4.5m in the hands and still fly earlier. So treat the number as a starting point, not a spec.
Your foil matters more than most people expect, too. A big front wing lets a smaller hand wing work, because the foil is doing more of the lifting. Someone on a 2000cm² front wing will get flying on a 4m in wind where someone on a 1000cm² wing is stuck. If you're building a setup from scratch, we'd rather size the whole thing together than sell you a wing in isolation — that's what the packages and deals are for.
Two other things worth saying
First: you'll be cold before you're underpowered. Wing foiling involves a lot of time sitting in the water, and Irish sea temperatures don't forgive a thin suit. If you're kitting out from zero, sort the wetsuit properly — it does more for your session length than any wing size ever will.
Second: don't buy anything until you've had a lesson. Two hours with an instructor tells you more about what size suits you than a week of reading charts. We run private 1:1 wing foiling lessons in Galway, and we'll put you on our school wings in a few sizes so you can feel the difference for yourself before a cent goes on gear.
Call in to the shop in Barna and we'll size you up properly, or book a lesson and find out on the water.
