A new class of dinghy?

You will undoubtedly learn faster and better if you are taught rather than self made (unless a genius) but the key to any activity has to be to get them to want to come back next time.  There has to be something to look forward to. 

Originally posted by iGRF Agree David Yacht, nail head. Ironically returning to SUP, what have I in my inbox this morning? A SUP company claiming to be the first to calculate a Stability chart, then a Glide capability index. Just the sort of thing that would be useful for dinghys marketing spin it might be, but it serves as a useful categorisation of their products and to a casual observer quite logical and rational.

Kona a brand I've flirted with on and off.

Here lets see if it cut and pastes

What is stability?
Kona has become the first company in the
industry to analyze one of the most important parameters
within stand-up paddling. Stability has a major impact in the
choice of board and we want the customer to find the right
board easier than ever before. When introducing the stability
number the customer can easily compare boards and find the
right one for their ability and needs.


Stability is the ability of the board to resist heeling and capsize. A board with low stability makes it more challenging to stand on, but often carries some performance benefits. A board with High stability makes paddling easier, but sometimes slower less efficient.



    
                            
   What is glide?
Not only have we introduced a way to compare boards easily, we
have also made a resistance analysis to find the glide of each board.
Glide is a term we use to talk about the ease of paddling. The higher
the glide number the easier the board is to paddle and vs versa.

Why is Glide Important?
The glide number is a ratio of volume to length and is important because
this helps to choose which board is right together with your
stability number. The longest narrowest boards have the highest
glide ability’s.

How do we calculate Glide ?
Using 3D models of our boards and Naval Architect computer analysis
methods, we calculate the glide number. This is then used to
optimize designs make changes in volume distributions, lengths,
widths and rocker lines.



And no I'm not intending to start selling SUPs again can't sell something I don't believe in just for money.

Stability is a well understood nav arch quantity ie you can assign a value, the transverse meta centric height that characterises the initial transverse stability of a hull very nicely.
“Glide” is more of a subjective quantity. I guess you could make a decent engineering estimate of a hull drag from its parameters perhaps regressed against physical measurements, for a given displacement. From that perhaps estimate distance travelled on single impulse ie paddle stroke. In fact f@ck it ballast them up and give each prototype a shove of a known magnitude in a swimming pool and measure it.

Sounds like a load of toss to me :-)
