Picked up the blank yesterday.
This is what I will start with (my planshape and nose rocker/kick pre-cut).
I have a lot of trimming to do, then shape the nose, rails and tail.
Things were looking like slow going for arm-muscle rail shaping. The 8" wood rasp cut well but was too small. The 10" surform worked but still wasn't going to be too speedy.
Then I discovered this 14" rasp at Tractor Supply Co. this morning. Much longer and wider cutting surface, sharp and coarse. Went to my other local farm supply hardware looking for a handle. Only thing that was big enough was a masonry trowel handle.
The rasp is for horse hooves. Never would have found this tool for shaping if I didn't live in middle of nowhere rural America.
Fantastic! You're making real legitimate and professional progress. Maybe not the way Toobs and Morey Boogie do it now, but they did a very similar process originally when it came to their top of the line boards. PS I like your use of the "Carpet Knife". Hadn't thought of adding one to my shaping bay before, but will now. No telling what I might use it for.

That which can be assorted without evidence was read in an illegal magazine.
Have used a "Ferrier's Rasp". For many years. In my case they are super speedy and aggressive for wider wooden stringers and wood tail or nose blocks. They do the job! Inherited a complete set once from someone who owned a couple of horses.

I am keen to hear a ride report. Do you think this 6 pound XLPE would support a properly attached foil?

Roger,
I'm too old now to be a credible test pilot. Only started riding BBs/KBs last year.
If I don't get skunked, I will have a chance for test riding in a few weeks. Otherwise, I'm considering testing at a wave machine later this year.
Regarding foil attachment, because the foam is semi-rigid but elastic, you would likely need some sort of mounting plate attached to the bottom (a carbon fiber, polycarbonate or ABS sheet as a base plate?).
I found the carpet knife on the ground several years ago (with new blades inside). I've been using it ever since. The one I found (Personna Blue Thunder) has been replaced by a new model. The Blue Thunder model seems well made and fits nicely in my hand.
When shaping prototypes, I like to go slow to avoid removing too much foam too fast. So I use as few power tools as possible.

My old handsaw made quick work of removing the scrap-foam tags.
Next, I remove the lip that attached the scrap-foam tabs with a carpet knife.

Hoof rasp removed enough foam for me to begin final rail shape.

I appreciate the input McD.
The 14" farrier's rasp is a handy tool for sure.
