Worth more for sure. But clark shut down over 3 years ago. So a board better be in pretty good condition at this point. No one had time to stock up on extra blanks. They just plain shut down production without notice. So unless you know a guy who had a garage full of blanks, its probably an old board... But to this day, i have NEVER purchased a board, rack or custom with other foam that I can say is anywhere near the quality of Clark... It is just plain better... It took years for imported foam to even become close to sub-clark-standards.... Im sure its better now, but i take extra special care of all my plus ones with Clark Foam. They cannot be replaced....
So yes, its worth more if in good conditions for sure.... My shaper just stopped bi**ing about sh**y foam recently... years after the fact... on the west coast, imported foam shipments were treated like giant underground drug shipments... You had to know a guy who knows a guy, willing to drive up to the bay with a truck and purchase it in a back alley. And the foam SUCKED!!!! It killed american board production for years.
good info. I bought a board off craigslist for $99 that has clark foam. It was made by JW Krahn , and it's 6'6x19.5x 2.5. It's kind of yellow with a sanded finish. The original owner fixed some of the dings himself which are a bit more colored but it's never been water logged and overall the shape is good. He said it was around 5 years old, but he was a summer surfer and didn't really seem dedicated. I was going to resell it at $175 hoping to get $135 or so out of it. I thought it would be worth a bit more than what I got it for.
I don't know if it's worth more to the end user in terms of paying more to get a board with a Clark core over some other foam maker's core. Maybe Zach's right... I don't know. But shapers loved the stuff. It was, at the time, the best product available, and the industry standard. In fact... it was hard to get much of anything else because Clark had a death grip on the market. After Clark shut down in 2005, there was a lot of BAD foam being produced to fill the void. Seriously garbage stuff that couldn't make it through a season. They shaped like crap, looked like crap, rode like crap, and literally disintegrated before your eyes. The rockers were whacked, the glue-ups were sloppy, the foam was very inconsistent.
However... competition between foam makers quickly improved the overall quality of plugs in the market. Some of the older foam makers who competed with Clark did well. Some of Clark's top guys went on to join forces and keep producing decent foam. Some new foam makers surfaced and started putting out really high quality products too. But it took years, and it's still debatable (and personal preference) whether they've matched Clark's quality, reliability, and consistency. US Blanks' PU foam, for example, is excellent. Surfblanks America/Australia is also said to be some of the best PU foam in the world right now.
But the upside of all of this is the mass production and excellent quality of EPS now in the market.... some really high quality stuff. The variety of plugs is nowhere near Clarks, but a good shaper can turn out excellent boards from not-so-ideal blanks, and not be concerned with overshaping... the biggest problem with Clark's blanks and all PU foam in general. He compensated with a great VARIETY of plugs to choose from, so you could get a close tolerance blank and never have to get into the "meringue" of the inner foam. But today's EPS hold's great advantages over ALL polyurethane cores, including Clark's, IMO. But it's not the industry standard, and never will be... because of production considerations. Not because it builds an inferior board.
Having Clark foam doesn't add value, unless the person buying the board is willing to pay more. When they first closed down people were willing to pay a little extra to have a board shaped out of Clark, but now US Blanks is about the same in quality and surfers today wont be able to tell the difference.
us blanks is essentially the same thing as clark now. purchased all the old equipment and formula.
Yes... but what they don't have are the molds. And that's what made Clark's blanks the best. Hundreds of different rockers... all of them developed over years (perhaps generations) of professional surfers and shapers. Tweaked, refined and perfected to within millimeters. If you knew what you were after, in terms of a specific shape from a specific plug, you could get there quickly and not have to make many adjustments. You never had to look at the numbers and say, "yea... I can get that out of that blank." You just went to the blank you knew worked well and followed the natural rocker of the blank, except for the last foot or so at either end, where you put your mark on the shape.
