tip to tip deck side it is. Only reason I asked is because I suspected there was a "proper" way to do it, but i found so many doing it other ways, i wanted to know the various ways so i can convert measurements. tip to tip works for me. thanks Bill
When I started off trying to copy boards onto CAD I always got the shape a bit wrong because we were measuring off flat outline templates. The flat was shifting our measures up to 1" so the outlines were never perfect. Figured out what was going on when I curved the templates to the rocker. Rockers worked out a bit better provided straight line distance from tail/nose was used.
This is one of those subjects that we've learned not to discuss. Kind of like politics and religion. Add "rocker apex" and "neutral axis" to that short list too.
There is no denying that the "true" straight-line length of a board would be the straight line one measures from the deck side. And there is evidently a long history leading to some shapers' preference for doing so, which deserves respect.
For me it comes down to whether I want to compare apples with apples, or apples with oranges.
In the shortboarding world for the last couple decades or three, the more common practise has been to call the board by the length of the template or planshape, which gets traced on the bottom. It also happens that this is the surface that is interacting with the water, so in my mind is the surface whose length I am more interested in. This is the side I measure.
Whichever way one measures these things, we have to take into account the fact that the outline curve is compressed in the areas with greater rocker curvature, and we factor these into the design of our planshapes.
And then we remind ourselves that this is all for fun.
You forgot "Spiral V"
Oooh, that sequence of letters shall never pass over my keyboard.
haha, thanks for the tip. My lips are forever sealed. I will just stand it up and take a guess, calling it to the nearest foot. :-D
...some 20 years ago or so I decided to not put the dimensions on the boards, like in most boards previous to the 80s.
In my view is really an error and provide plenty of problems with the possible customer, that for example, had a "5 10" that did not worked for him; so he thinks that ALL the 5 10 do not work for him. Most think that way. Other problem is a possible customer that wants a 5 10 but in reality he would be better with a 5 9 or 5 11, to say something.
That makes sense actually, let them measure it THEIR way! Good idea! I am only making them for my family, not selling any,
