Sun, surf, sand ... auction? The 5th Biennial Vintage Surf Auction is taking place at the Blaisdell Exhibition Halls today and tomorrow, and if you happen to own a vintage board and want to know its value, "Antiques Roadshow"-style appraisals will be taking place between noon and 4 p.m. today.

There is no fee for the appraisals, which will be handled by six experts.

"We have, without a doubt, the best collection of surf memorabilia," legendary surfer and event producer Randy Rarick said. "We're covering over 100 years of surf memorabilia here."

The main auction consists mainly of surfboards shaped in the early 1920s through the 1980s. It includes old plank boards, hollow boards, "Fish" boards and boards shaped by masters such as Matt Kivlin, Dick Brewer and Gerry Lopez.

The silent auction consists of all types of surf memorabilia. There will be movie posters, artwork, trophies and books. Some items are priced as low as $25.

"This is a gathering of all these artifacts in one place and one time. It took me two years to combine all of these," said Rarick.

The top sellers will likely include one of the first foam sandwich boards, extremely rare. One of only about 50 made, the board was shaped in 1949 by Bob Simmons and was owned by James Arness. The board has plastic foam sandwiched between teak plywood and features jigs that allowed for the first rocker and scoop nose. There are also a variety of the best wood boards, crafted before the advent of plastic foam, to be sold during the main auction.

Other auction highlights include an original 1940s paddleboard with viewing box and swim suit from the Moana Hotel; a 1973 Lightning Bolt board shaped by Gerry Lopez; a 1969 "The Fish" shaped by Rick Value and owned by "surfing's divine prince of decadence," Bunker Spreckles.

Rarick said he has repaired, refurbished or totally restored all fiberglass boards to like-new condition. Most wood boards are in original condition, with minimal wear and tear. Items auctioned range in estimated value from $20 to $35,000. All proceeds will be divided and distributed to the Duke Kahanamoku Foundation, the Surf Heritage Foundation and Surfrider Foundation, O'ahu chapter.

Admission is free, and there is a $25 bidding fee. Visit www.hawaiiansurfauction.com for more details and exclusive peeks at some of the items that will be for sale.
