I want as little flex in the whole system too. When I tell my gear to do something, I don't want it bobbling and wobbling around, or needing to be waited for or compensated for, and I don't want it moving around under me in response to the water or transmitting wobbles.Foil wrote: ↑Tue Oct 15, 2019 9:30 amSurely a little flex in Moses carbon masts for freeride is a good thing?
it acts like a damping device, to cancel out the little bit of turbulence that happens around the rig under the surface,
as long as its not too flexible for the use its being subjected to.
Racers and speed freaks will want masts that have less damping, more stiffness, less energy absorbing factors like softness,
and moses do account and adjust their masts just for this, the entry level 91 cm mast is very soft compared to the 111 mast or even the 101 mast, the carbon lay up from the 91cm mast to the 101 mast is a jump from 20 layers to 25 layers, and the extra stiffness can be felt quite easily when you twist the mast with the fuse connected, or secure the mast and rock it back and forth, the difference is there to be seen or measured if you are that keen to pin down the numbers like I did last year,
the 91 cm moses carbon mast is silly soft compared to the 101, and how it compares to the other moses race masts must be jaw dropping.
but are these super stiff masts above the 101 desirable for the average joe, foil freeriders?
or are they just not great fun to use, smooth V jittery maybe?
I don't know
but there has to be a point where super stiff is not great to use, no? yes?
what I do know is I want to change my shallow water 84cm Aluminium slingshot mast for a carbon mast, its too heavy by far.
once you own carbon you are so aware of how nice and light translates to feeling good about your lightweight rig,
heavy kit is a bummer for most.
So it sounds like carbon is superior to aluminium for stiffness and weight (but not price) when comparing masts of similar thickness and length. However, if the manufacturer decides to make the carbon mast on the ligher side (as appears to be the case with Moses) then you end up with a light weight but flexible mast.BWD wrote: ↑Tue Oct 15, 2019 2:23 pmFor the same weight/stiffness the carbon can be thinner for less drag, and the hydrodynamic profile can vary from root to tip. Usually near the top, it is thicker for strength and stiffness, farther down it is shaped to avoid ventilation, closer to the bottom optimized for lowest drag.
Aluminum on the other hand, is a uniform extrusion, for which more stiffness means higher section and more drag, or much thicker walls and high weight. Thicker is ok if you aren’t looking for speed, but weight is not so popular.
Most people only know what they ride.tomtom wrote: ↑Tue Oct 15, 2019 7:04 pmRight now considering how very flexible some mast are i dont think for freeride is that much important. Why? Because if it was that much important everybody will immediately feel difference and will be death obvious that mast must be super rigid. Whole situation when some prefer that other that and nobody really know /look at french foil making forums/ indicate that it isnt as important /to some reasonable extent/. Fuselage is different matter and everybody WILL feel soft fuselage - it will vibrate and causing heavy drag.
