Lost Party Platter Double Dart 5'9 Surfboard – 40.5L
The Lost Party Platter Double Dart 5'9 Surfboard is an ultra-wide, low-rocker small-wave groveler built to turn weak surf into something worth paddling out for. Designed by Matt “Mayhem” Biolos, the Party Platter combines generous width, full rails, a flat deck, and efficient parallel outlines to generate speed and glide when the waves are lacking. Lost describes the Party Platter as an ultra-short, extra-wide small-wave design influenced by boards such as the Bean Bag, Couch Potato, and Plank.
This 5'9 version comes in at 22.5 inches wide, 2.66 inches thick, and 40.5 liters, giving surfers plenty of foam and stability without requiring a traditional longboard or mid-length. The dimensions match Lost's current published stock dimensions for the 5'9 Party Platter.

Designed to Make Small Waves Fun
The Party Platter is purpose-built for days when conventional performance shortboards struggle to get moving. Its low rocker and parallel lines are designed to enhance speed, drive, and glide, while the flat deck and full rails provide a stable, smooth platform underfoot. Conservative bottom curves incorporating concave and vee help create lift while maintaining rail engagement.
At 40.5 liters, this 5'9 Party Platter packs substantial flotation into a compact package. That combination makes it an appealing option for surfers looking for easier paddling and wave entry while still retaining the maneuverability and responsiveness of a shortboard-style shape.
Double Dart Carbon Construction
This Party Platter features Lost Double Dart construction, a premium EPS and carbon-fiber technology designed to deliver a lightweight, lively feel. Lost explains that Double Dart uses its Carbon/S-glass hybrid fabric with the board wrapped top and bottom in a carbon-fiber shell. Shortened rail laps are used to help preserve flex and torsional movement rather than creating an excessively rigid carbon board. A 4 oz fiberglass cover layer completes the construction.
The result is a high-performance construction designed for surfers who want the speed and responsiveness associated with carbon/EPS surfboards while retaining usable flex through turns.
Futures Tri/Quad 5-Fin Versatility
A Futures 5-fin setup gives this Party Platter plenty of tuning potential. Run it as a thruster when you want more control and a familiar feel through turns, or switch to a quad setup when maximizing speed and drive in softer surf is the priority. That versatility complements the Party Platter's small-wave-focused outline and makes it easy to adjust the board's personality to the day's conditions.
Squash Tail Performance
The squash tail provides a versatile combination of surface area, release, and control. Lost currently categorizes the Party Platter among its squash-tail models as well as its dedicated groveler designs. Combined with the wide outline and low rocker, the tail helps keep the board lively through weaker sections while still allowing responsive direction changes when a pocket presents itself.
Who Is the Lost Party Platter For?
The Party Platter is an excellent choice for surfers who want to maximize their wave count and have more fun in small, weak, and less-than-perfect surf. Its wide platform, generous volume, and stable rails can make it approachable for less-experienced surfers, while experienced surfers can take advantage of its speed, compact length, and responsive construction to push small-wave performance.
For surfers who normally reach for a longboard when the waves get tiny but would rather stay on something shorter and more maneuverable, the Party Platter offers a compelling alternative. Lost's own description positions the design specifically as an ultra-short, extra-wide answer to very small surf.
Double Dart Care Note
Because Double Dart boards use lightweight EPS foam with a dark carbon-fiber shell, extra care should be taken around heat and direct sunlight. Lost warns that carbon boards can absorb significant heat and recommends avoiding prolonged exposure in hot cars or direct sun. A heat-reflective day bag is recommended when transporting or storing the board around the beach.
