Monk Fish Q&A
What size Monk Fish should I get?
The Monk Fish is a fish, so ride it shorter and wider than your regular shortboard, with a tad more volume: we recommend 1 to 2 liters more. Comparing stock dims, it runs about 2" to 3" shorter than a Driver 3.0 of the same volume. For example, if you ride a 5’11 Driver 3.0 (28.50 L), look at the 5’8 (20.00" x 2.38", 29.90 L). Stock sizes run from 5’6 (19.50" x 2.25", 27.00 L) to 6’4 (21.00" x 2.75", 39.60 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 Monk Fish use?
The Monk Fish has five fin boxes (FCS II or Futures), so you can ride it as a thruster or a quad. Neither FCS nor Futures lists this model in its …Lost guide. The Monk Fish is built to be surfed aggressively and hold in steep, tight waves, so we go with the raked family both brands pair with …Lost’s performance boards; for a more traditional fish feel, the FCS II Split Keel Quad or Futures Mayhem Evil Quad also suit it. The template to look for is a raked, drive-oriented fin: on FCS II the Mayhem Driver Tri (Small, Medium, Large), with the Mayhem Driver quad rears (Medium, Large) for a quad. FCS classes the Mayhem Driver as a Carver-family fin: an elongated template with more sweep (rake), built for hold and longer, drawn-out turns. FCS sizes these fins by weight: Small 120–155 lbs, Medium 145–175 lbs, Large 165–200 lbs. On Futures, the Mayhem 3.0 5-Fin (Medium, Large) gives you the same rake template in a thruster-plus-quad set, or use the R-series Blackstix (R4, R6, R8) as a thruster. Futures sizes its fins as Small 95–135 lbs, Medium 125–175 lbs and Large 165 lbs and up.
What makes the Monk Fish different from other fish?
Its vee bottom. The tip-to-tail vee lets the board transition effortlessly between turns and keeps it from having the “flat” feeling many fish have when surfing, so it can be surfed more aggressively than fishes of the past. It paddles really well, slices through surface chop with ease, and an exaggerated rocker profile keeps it surfable in tight, steep waves.
What waves is the Monk Fish for?
Average to good waves, from thigh-high-plus to head-high-plus. Unlike most fish it is comfortable in steeper, tighter waves thanks to its rocker and vee, and the round-tail option lets it handle larger surf.
What is the history of the Monk Fish?
The Monk Fish is one of …Lost’s classic fish designs. Cory Lopez rode a Monk Fish round pin in his seminal Skeleton Bay segment in the film “5’5 Redux”, and when Matt Biolos designed the Retro Tripper in 2021 he described it as similar to the classic Monk Fish round pin.
