The California Board Company Magnum 44 is a 44 by 23 inch bodyboard with an EPS core, arm wells and a coil leash. Its Amazon listing now shows it as currently unavailable, and an Amazon search on 2026-10-21 found no other California Board Company bodyboard, only a surfboard and a skimboard. Two current boards of about the same size are the Morey Big Kahuna 44 and the Body Glove Big Tuna 45.
These notes are for someone who searched for this board. This page used to call it the MMAG; the listing and the graphic on the deck call it the Magnum. The notes cover what its listing says, who a 44 inch board fits and two current boards of that size. To compare boards across all sizes, see our bodyboard buying guide. WaterSportHQ editors have not ridden these boards.
What the Magnum 44 listing says
The listing (B0041E9NG8) is still online without a buy button. California Board Company lists:
- Size: 44 x 23 x 2.75 inches.
- Core: waterproof EPS (expanded polystyrene).
- Deck: PE, with a molded contour, arm wells and thumb bulbs.
- Bottom: high density polyethylene slick with bottom channels.
- Tail: crescent.
- Leash: dual swivel coil wrist leash, included.
- Warranty: 30 days.
The listing names no stringer, no rider weight and no skill level.
Who a 44 inch board fits
By the WaterSportHQ editors’ rule-of-thumb chart in the body board vs boogie board guide, a 43 to 44 inch board fits riders about 6 ft to 6 ft 3 tall and 180 to 220 pounds. The board should reach from your knees to about your chin when stood on end.
By the same chart, riders under about 5 ft 9 fit a 42 inch board or shorter. A 44 inch board is too much board for most children.

Sources: the Amazon listings for the three boards, checked on 2026-10-21. Only the Big Kahuna lists a weight limit, and its listing gives two (see below).
Morey Big Kahuna 44
Morey sells the Big Kahuna for “bigger riders or those seeking extra float”. By the editors’ chart, 44 inches suits riders about 6 ft and up. Its size row gives 44 by 23 inches, the same as the Magnum, but Morey’s size chart image gives 21.7 inches wide. It has an EPS core, an IXLPE deck, an HDPE slick with graduated channels, a crescent tail and a coil leash with a pre-installed plug.
It is the only board of the three that lists a stringer. Morey says the single REX stringer adds “durability and flex control”. The listing gives the item weight as 1.29 kg (about 2.8 pounds) and the skill level as beginner, so it is not sold as a board for advanced riding.
The listing contradicts itself on rider weight. Its “Weight Capacity Maximum” row says 185 pounds, while Morey’s size chart image says riders of 160 to 250 pounds, 6 ft and over. Riders between 185 and 250 pounds should check with Morey before buying.

Body Glove Big Tuna 45
Body Glove sells the Big Tuna as a large bodyboard for tall riders. It has an EPS core, an XPE deck, an HDPE slick with dual channels, a crescent tail and a coil leash with a wrist cuff. The age range is listed as adult.
It is an inch longer than the Magnum. By the editors’ chart, 45 inches fits riders about 6 ft 2 and up and 200 pounds and up. The listing gives no width and no stringer.

What to check before you buy
- The size: pick by your height and weight. For more on fit, see bodyboard sizes.
- The board on arrival: look for bubbles or lifted skin along the rails while a return is still easy.
- The leash plug: check it is set firmly in the foam before the first session.
Editors’ rule of thumb: rinse the board in fresh water after salt water, and keep it out of hot cars and direct sun, since heat can make the skins bubble.
