Flying Words: Is It eFoil, e-foil, or Efoil?
One sport, a handful of spellings. Here's where the word came from and what to use when you just want to get out and fly.
People spell it a dozen different ways: eFoil, e-foil, efoil, E-Foil, even "electric foil board." If you've searched for the sport online, you've seen all of them. So which one is correct? The short answer: it depends who you ask. The longer answer is a fun little tour through branding, English habits, and how new words settle into everyday use.
Where "eFoil" Came From
The word is a mashup of "electric" and "hydrofoil." A hydrofoil is the wing under the board that lifts you up out of the water; the "e" out front just means there's an electric motor doing the work instead of a wave, a boat, or a kite. Put them together and you get eFoil — electric hydrofoil. The capital-F styling came largely from the brands that popularized the sport, who wrote it that way in their marketing.
Why There Are So Many Spellings
1. Normal people don't think like brand style guides
When you're typing a caption with one thumb, you're not checking where the capital letter goes. "efoil" is faster, and most people reading it know exactly what you mean.
2. Traditional English likes hyphens
English has a long habit of hyphenating compound words when they're new — e-mail, e-commerce, e-bike. By that logic "e-foil" looks perfectly natural, and plenty of writers default to it.
3. Brands experimented early
Different manufacturers styled the word differently in their early materials. There was no single authority, so several versions spread at once.
4. Social media is casual
Hashtags flatten everything to lowercase and strip the hyphens. #efoil, #efoiling, #efoillife — the platform itself nudges people toward the simplest spelling.
So What's "Right" for Regular Riders?
Honestly? Any of them. Language follows use, not the other way around. If you're talking to friends, posting a clip, or telling someone you tried it last weekend, nobody is grading your capitalization. Write it the way it feels natural and get back to the water.
When You Might Care About the Spelling
There are a few moments where being consistent actually helps:
1. Posting your session online
Using the common spellings and hashtags makes your clips easier to find — and helps other riders find you.
2. Leaving reviews
When you write about a shop, school, or board, matching the spelling people search for helps the next rider find the same recommendation.
3. Talking to people new to the sport
With first-timers, a clear, simple "eFoil" usually lands better than a hyphenated or all-caps version that looks like a product code.
A Quick Guide for Everyday Use
- eFoil — the most common branded styling; great for clean, readable writing.
- e-foil — traditional and tidy; fine in formal or older-school writing.
- efoil — perfect for hashtags, captions, and fast typing.
Pick one, stay consistent within a single post, and you're done.
The Term Is Still Evolving—Just Like the Sport
eFoiling is young. The gear keeps getting better, more people keep trying it, and the language is still settling. A few years from now one spelling may win out completely — or all of them may simply coexist. That's normal for any word that arrives faster than the dictionaries.
Final Takeaway
eFoil, e-foil, efoil — they all point to the same thing: a quiet electric board that lifts you up and lets you glide over the water. Spell it however you like. The only version that really matters is the one you experience for yourself.
Spell it however you want—just come fly.
The best way to settle the eFoil debate is to get on the water and feel it. Book a lesson and find out why one ride is impossible to forget.
