Deciphering dimensions

How would one interperate these dimensions:

+3/4" tail is good for noseriders

+1/2" nose last 24" +1/2" tail last 10" is good for all around boards.

I am thinking of making a longboard, and I want to understand as much as possible before I start.

Thanks to all who can offer assistance.

those measurements refer to variations in rocker on a blank (been reading up on the Clark catalog, have we?!?). +3/4" tail means to increase the natural tail rocker (specified in the picture in the clark catalog) by 3/4". +1/2" nose last 24" means that the curve of the natural nose rocker is increase by 1/2" starting 24" back from the nose; and in that same respect, +1/2" tail last 10" means that the tail rocker on that same blank would be increased by 1/2" starting 10" up from the tail.

+3/4" tail means there is an additional .75" of rocker in the tail section. More tail rocker with a flater nose rocker on a longboard is thought to help the tail lock into the section of the wave to fascilitate noseriding.

+1/2" nose last 24" +1/2" tail last 10" is good for all around boards. Means simply that there is some kick or sharp upturn in the rocker at both tail and nose. And yes this is good for all around. More nose rocker means less chance of pearling, coupled with additional nose rocker with some tail kick and the board will turn a bit quicker, but will be a tad slower in trim.

It’s really all about tradeoffs. Figure out what you want to do and then go ffrom there. But if rhis is your first longboard, I would stay as neutral as possible. Don’t go the extreme noserider, or extrme HP longboard route

A good idea is to read the blank descriptions of the Clark foam catalog. Pick a size that you want and then read each blank description for details. Well, honestly you shold read the entire catalog as there is lots of good stuff in there.
