I've been riding prone boards for a few years now, tried some production stuff and been destroying most everything i touch.
I'm 100kgs and do alot of small wave shallow water stuff, alot of really agressive pumping and alot of hard groundings. A few rock encounters.

Really tired of destroying boards and also really intolerant of weight (because of all the pumping). I went through a few production boards, one got sent back day 1 for being too heavy and another i cracked the box on my 3rd session. My own boards (vac bag carbon over eps) did better but they'd still crack and take up water.

For my latest board i got my hands on a solid block of 3" 3lb divinycell. Really expensive way to build a board but its been great.

I did my usual track reinforcement which was probably overboard. Built the chinook boxes into carbon pilars connecting the bottom and deck. Vac bagged the whole thing with 2x 6 oz carbon.

Came out a little heavier than i wanted but not terribly so. I cant recomend the material highly enough. For prone sizes the extra weight isn't a deal breaker and the piece of mind of knowing that its never going to take on water is great. It also just feels incredibly stiff, i just love it. Been wailing on it in all conditions, bailed and watched it wash over the rocks and it came out fine.

$250 to do one board. With what most brands are charging for a prone board is definately in the realm of possibility.

I don't think anyone has any interest in making a forever board though. Really kills future sales.

for a 30L board 3lb foam is only about a 1.5 pounds heaver than 1.5lb foam. sweet that it will never take on water, and the board must be wicked stiff

We make a full sandwich full carbon prone board in our FU boards a 4'5 x 31L and that thing is bombproof. I use it as my prone but also my foilboard when i take the Ski out as you can just throw it on the ski and not worry about hurting it, even run it over a few times and she is still like the day we made it.
Price we feel is pretty fair for a board like this at $999 The blue one on this link is the Full PVC sandwich. www.oneoceansportsaustralia.com/shop/foil-prone-boards

You are right in that maybe not the best for business as I don't see many getting wrecked and needing replacing. Weight wise the 4'5 is about mid to high 2kg range which is maybe just a touch heavier than our full carbon skin boards.

Paul,

Those boards look fantastic and that weight is great! I feel like sandwich is really hit or miss between different manufacturers. I've gotten my hands on board that went right back in the box at the airport, 4kg+ 4'6" prone boards.

It's also brutal not being able to put hands on anything other rippers are riding(my crew are the only foilers around), add to that being as big as I am I really have trust issues. When I find something that works I have a hard time moving.

I'll def keep an eye out for your product stateside!

Yeah understandable as with foiling still quite new there has been some average stuff put on the market and in some **** constructions. We have worked really hard on keeping the weight right down without making boards so fragile that they ding just at the sight of them and its always such a fine line as people want super light but also want super strong. When we mold the boards and do the full sandwich this is by far the best for the strength to weight ratio and I love this construction as I know people are getting the best board for their $$$$, the Carbon skin boards are a bit harder to get the balance right and it's taken quite some time to really get a perfect balance, they are never going to be as strong as the sandwich but we have now got them pretty good and the weights are nice and light.

We are still always pushing the weight to strength side and finding new little ways to tweak the construction and save a few grams is our main goals on this side at the moment.

Cool to see you make your own as well and it does feel super nice to ride a board that you made with your own hands!!

Yeh nice pics, simple outline and bottom - looks like a good paddler. Reminds me a bit of my carbon YOB wing / Sup board actually and I know that paddles forward well as I've proned it for sh1ts and giggles. Be good to try one for sure.
