Re: Destroying my Slingshot Ghost Whisperer

So, ereytime i go out i hit something. I am destroying my front wing. I was in mex, wave riding, i came off of foil and hit a coral head. I was bakers bay bahamas, fell off my foil, and it got hung up on the reef and just sat there. I came into the event site this summer a little hot, and came down...

Re: Do I bother to get a 60cm mast?

YES, dragging so long puts you off hydrofoiling - we have one spot with same conditions, and we have all tried this spot once (sand so no risk), but it is a real turnoff and we all seek other spots and never return to this otherwise best TT spot with a good social atmosphere. So if this is your loca...

Re: Drysuit or wetsuit if you anticipate a swim?!

They have quite some buoyancy indeed, a little bit more tiring because of the thickness yes, but not an issue IMO. You are talking about a swim without your board I reckon - why ? It would be much better to swim on your board, and here even a normal membrane drysuit works fine as you can swim/paddle...

Re: How do you dismount?

I do the same - ride in foiling really high over the banks, but still not so high I risk ventilating, and then leaning backwards both foil and me so it does not ride further, but "lands" gently on its side. Not very graceful no, and you have to turn the foil around to walk to shore afterwards - but ...

Re: How to turn a hydrofoil - and what is YAW ?

Interesting aspects and views shared in this thread now - have been away and not read in detail nor time right now, but like that there are so many who gives their input and share :D However, I will say one thing, being an engineer working with design, analytics, and aerodynamics/design and a lot of...

Re: How to turn a hydrofoil - and what is YAW ?

I don't see any misuse of terms.

If many with knowledge says I do, that I am wrong and misleading, I would of course reconsider.

Re: How to turn a hydrofoil - and what is YAW ?

I still say you are wrong Mossy, and can in fact show that planes can turn fully around with wings perfectly level because of horisontal COE coming from the fuselage can be well in front of the rudder so the resulting sideways force acts just like banking and pulling the elevator, but no reason to w...

Re: How to turn a hydrofoil - and what is YAW ?

Yaw is not what turns a hydrofoil, rolling in the direction of turn redirects the upwards lift vector towards the inside of the turn and induces the change of direction. Just like stepping on a rudder pedal in a plane doesn't change direction, only points the nose in a new direction. In a plane whe...

Re: Moses 2018

Bugger Frank - we have fortunately no seaweed here now not even with the changed wind direction.

It is a PITA in late summer at some locations which you avoid then :(

Impossible to test anything in this...

Re: How to turn a hydrofoil - and what is YAW ?

Thank you :D - and I am sure you are right Peert, it origins from sailing of course, even if used most often in aviation now, my mistake. My background in flying and aerodynamics/design, and the fact that when you google it today (just checked) yaw is mostly used in aviation, made me erroneously thi...
