Who - The Lost Surfboards '97 AI Exacta PRO is designed for intermediate to advanced surfers looking for a refined, high-performance shortboard with authentic '90s DNA. Best suited to surfers who appreciate fast, precise rail surfing and want to experience the feel of one of Mayhem's most iconic performance designs, scaled for modern riders.

When - The '97 AI Exacta PRO performs best in quality waist-high to overhead waves with enough push to unlock its speed and drive. While inspired by powerful Hawaiian surf, its updated sizing allows it to excel in a wide range of everyday performance conditions, especially clean point and reef breaks or punchy beach breaks.

What - The '97 AI Exacta PRO is an exact recreation of one of Matt "Mayhem" Biolos' original performance boards built for Andy Irons during the winter of 1996/97. Painstakingly recreated from Andy's original board—which resurfaced more than 25 years later—the design has been digitally scanned and reproduced with period-correct details, including the original rocker, foil, outline, glassed-on UltraLight Hex-Core fins, leash plug, hand-written dimensions, and recreated Posca artwork. Featuring a narrow, elongated outline, thin foil, dramatic needle-nose flip-tip rocker, pulled-in squash tail, subtle hip, soft forgiving rails, and a single-to-double concave bottom with slight vee through the tail, the board blends radical '90s styling with surprisingly modern bottom contours. While visually aggressive, its smooth center rocker allows exceptional speed and flow, making it remarkably relevant by today's performance standards. Available in a modern size range, the '97 AI Exacta PRO captures the look, feel, and performance of one of surfing's most iconic eras while remaining accessible to contemporary surfers.

1997 A.I. Pro Q&A

What size 1997 A.I. Pro should I get?

…Lost strongly recommends riding it about 2" longer than a typical modern performance shortboard, and says to expect a measurably lower volume than you usually ride. The stock dims bear that out: an A.I. Pro runs about 2" longer than a Driver 3.0 of the same volume. Stock sizes run from 5’8 (18.13" x 2.25", 24.25 L) to 6’4 (19.50" x 2.50", 32.25 L). If you don’t know your volume, use the Volume calculator at the top of our …Lost 3D board builder: enter your height, weight, skill, fitness and the waves you surf, and it recommends a volume by board type, from shortboard to fish, hybrid and mid-length. Our shop staff can help you pick a size.

What fins does the 1997 A.I. Pro use?

It is a thruster. The original board had glassed-on fins, and …Lost builds the re-creation with glassed-on fins too. We stock it with glass-on fins and with FCS II or Futures boxes. Neither FCS nor Futures lists a fin pick for this model. For …Lost’s current performance shortboards, the Driver 3.0 and Formula-1, both brands recommend a raked, drive-oriented template, and that is what we suggest for the boxed versions. On FCS II boxes that is the FCS II Mayhem Driver Tri (Small, Medium, Large). FCS sizes these fins by weight: Small 120–155 lbs, Medium 145–175 lbs, Large 165–200 lbs. On Futures boxes it is a Rake fin (drawn-out turns, drive): the Mayhem 3.0 (Small, Medium, Large) or the R-series Blackstix (R4, R6, R8). Futures sizes its fins as Small 95–135 lbs, Medium 125–175 lbs and Large 165 lbs and up.

What skill level is the 1997 A.I. Pro for?

…Lost rates it for intermediate, advanced and pro surfers, and says to expect to ride it at a measurably lower volume than you usually would.
