Quick Answer: Is the 85cm / 65cm setup a good choice?
Yes – this is a versatile setup that works for most riders, offering good stability while still allowing progression into more advanced riding.
It’s a solid choice for intermediate riders and confident beginners.
---
Why choose the 85cm mast?
The 85cm mast is the standard “go-to” length for most foiling disciplines.
It gives you:
- More clearance over chop
- Better control at speed
- Improved carving and turning
Compared to shorter masts, it allows you to ride more comfortably in real-world conditions without breaching the surface.
---
Why choose the 65cm fuselage?
The 65cm fuselage is the shorter option in the Armstrong alloy range, designed for a more responsive feel.
It offers:
- Tighter turning
- More playful ride
- Faster response between front and rear wing
Compared to a longer fuselage, it sacrifices a small amount of stability in exchange for better manoeuvrability.
