WHAT FOIL?
Between different manufacturers almost all items vary although there are many similar trends. Mast length, fuselage length, wing size, shape and position are your main factors when looking at foils.
The front wing type is probably the biggest decision to make. Most manufacturers make 2 or three wings. If they make 2 then the large front wing is normally around 800 sq. cm and will be best for getting up early in lighter airs. Where manufacturers make three wings then if you’re heavier the largest wing might be the best option for maximum lift whilst the middle wing a good light wind option for lighter riders. To start with, lift helps the learning process and also helps you cover the lightest wind range or even get out on smaller sails earlier. If you’re looking to foil in higher winds or go faster then you can always add small wings in the future.
Mast length may or may not be an option. For top performance, longer masts, typically 95-100 cm are best. They give you higher ride heights, work well in swell and allow you to go faster. Shorter masts are around 75-85 cms and tend to be a little better when learning, as you get a feel for the length of the foil more quickly and when you do crash you won’t be as high.
Fuselage length will control stability, but the key ingredient here is how far apart your wings are. The further apart the wings the more stability you’ll have. The further forward the front wing on the fuselage, or from the mast, the more lift you’ll have under your front foot. The closer to the mast or further back the wings, the more lift you’ll have through your back foot. Wings closer together or shorter fuselages will increase manoeuvrability, whilst sacrificing some longitudinal stability.
Currently all the above variations come in full carbon setups and also alloy / carbon or even alloy / G10 variations. If you’re looking at travelling a lot with your foil the alloy /carbon or alloy / G10 combinations tend to be the setups you can fully pack down and remove the mast from the fuselage for easier transport.
