Hydrofoil FAQ

So you’ve been doing a little research and now you’re utterly confused as to what might be a suitable foil for your entry into this new incarnation of ‘I must now fly on water’

Getting the right foil might be a simple decision such as ‘how much you can afford’ but making sure the foil you do decide on reflects what you want to do with it.

If you are a heavier rider  90kg+ wanting small wave performance you’ll want to look at hydrofoils with bigger front wings , have a look at the pictures below.

These detail a Particular brands biggest wing of the previous year to its biggest production model of 2018 (quite a difference )

In fact if downwind swell catching/riding are your thing …the bigger the better so you can literally soar like the Albatross.



hydrofoil which mimics the classic aeroplane wing will generate the most speed and lift, however lots of foils have downturned wingtips in the front wing.

Downturned wingtips mean the foil loses a little lift and speed but aids the wings turning radius without risk of breaching the surface or ‘ventilating’ (nerdy technical term) like a flat wing can do. Therefore most of the guys you will see surfing on foils will tend to favour downturned wingtips but this is not always the case.

You may note how thick some foils are , this aids in smooth lift at low speeds (ie you paddling into a wave)

This is why you will see lots of brands using similar designs in the front wing (wide depth and curved down wingtips). Some wings will have more depth (low aspect ratio) and this will characteristically mean very good lift at lower speeds, however the turning will effect pitch and roll. A mid aspect ratio wing delivers stability in both pitch and roll, which is vital for confident wave riding but a little harder to get going at lower speeds if the wing is not thick.

Tail stabilizer wing

Most people think that the front wing is the most important and you may disregard the rear stabilizer as not being particularly important however it is what most brands are working on the most.
Its a 50% – 50% mix with the right balance
Depending on the stabilizer profile, shape, angle, size, your foil can react completely differently with : speed, pumping, accessibility, manoeuvrability and stability.
The surface area and volume of the front wing changes massively from brand to brand. These variables mean The tail stabilizer has to work perfectly with the front wing and clean up any turbulent flow from the mast and fuselage to minimize disruption of stability.
Anhedral wings  i.e wingtips which are downturned like the red tail wing above resist yaw better than flat wings, making them more stable.

We hope you found this post informative and don’t hesitate to get in contact if you’re thinking seriously about joining the SUP /surf  foiling crew in your area and maybe blazing your own path !

We have foils and boards available and install boxes if you choose to retro fit to an existing board which your local shaper can help you with .
