Artz, not me on the SUP cat. GL shaped that hull for me a few years ago. 18 feet by 16 inches and it was perfect to my eye.

Just curious, are there any prospects with regard to UV cure epoxy?
doh! missed you at the show. so, an easy one. the addF i got from sam a year or so back? how long do I keep it? I'm getting ready to do a coupla compsands this summer. love your travel pics. glad to see your knees are working well.
Hi Laslo, thin t he resin with about 20% xylene. Maybe try one of those small foam rollers, I was always able to get the resin really thin with those. Let the resin breathe for a couple days after to let the xylene leave.
Hi Artz, SUP design is interesting as far as race boards go because they are true displacement hulls. As such the narrower and longer you go the faster the board will paddle. It's a hull speed issue. I've paddled with racers on the same size equipment and in a mile long race they'd beat me by a couple lengths (I'm no racer). It takes some serious horse power to get a displacement hull to run faster than the following wave you've created. If your in a class race pretty much the winner will be the one with the narrowest board. Racing in unlimited takes a real gorilla to push that much board especially if there's wind. All this stuff already happened in kayaks and as the kids grew up on narrower equipment they began dominating. So they finally classed all the measurements.
Thanks Greg, nice links.
Hi Newschool, I've worked on UV epoxies, I've had numerous samples. The problem is that the epoxy oligimers need a very broad spectrum UV. The lighting systems cost upwards 100K. Not many shops could swing that. There's some other high solids options out there but the results are pretty cheesy for board building. Boards require high end physicals.
Hi Pompano, good to see you again. Add F doesn't last forever and the only way to know is to test it. Yes the knees are good and the travel photography has been fun.
2 Epoxy questions.....sorry they're tough ones.......can't find it anywhere.....figure you're the right guy.....if anyone....
What impact do common fillers used have on the properties (Tensile strength modulus and % elongation) of cured epoxy. Stuff like Microballoons, cabosil, "q-cell" graphite powder milled fibers. etc.Trying to understand when to use/not use what and what i need to concerned about overdoing it the some fillers.
What if anything could I add to an epoxy that's readily available(ish) to make it more "rubbery" and increase % elongation at the expense of other properties, if I desired this property over others.
