The Morey Mach 7SS is a 41.5 inch bodyboard built for drop-knee riding, with a polypropylene (PP) core, two power rod stringers, X-Flex mesh, a TC8 deck and a Surlyn slick. Morey’s size chart puts boards of 41 to 41.75 inches at riders 125 to 170 pounds and 5 ft 7 to 5 ft 9. Morey says the core “can be hard to control for beginners”, and the listing names no leash.
These notes cover what the Mach 7SS listing says, who it fits and what it is not built for. To compare boards for beginners and other rider sizes, see our bodyboard buying guide. WaterSportHQ editors have not ridden this board.
What the Mach 7SS listing says
The Amazon listing for the single board (B00553WO4M, Morey part 82542), checked on 2026-10-21, gives:
- Size: 41.5 inches, the only size offered. It gives no width, thickness or board weight.
- Core: PP, which Morey calls “100% hydrophobic” and “best suited for temperate to warm waters”.
- Stringers: dual power rod stringers, “a dual composite carbon strength tube” in the front of the board.
- Mesh: X-Flex mesh across the core under the deck skin.
- Deck: TC8 polyethylene, with knee contours for drop-knee riding.
- Bottom: Surlyn slick with dual channels.
- Tail: crescent.
- Leash: none named. The included components row lists only the board.
Morey says the board has a slimmer nose to prevent nosedives and a wider tail for sharp turns.
The listing contradicts itself on skill level. The single board’s row says advanced and the gallery icon says expert, but the two-pack bundle’s row says beginner. Morey’s own bullet says the PP core is “faster and stiffer” and “can be hard to control for beginners”.
The earlier version of this page gave 43 inches and 6.15 pounds. The current listing sells only 41.5 inches and gives no board weight.

| 43 in | 170 to 210 lb | 6 ft 1 to 6 ft 3 |
Source: Morey’s sizing chart on the Mach 7SS listing, checked on 2026-10-21. The chart covers Morey’s whole range; the Mach 7SS comes only in 41.5 inches. The listing gives no maximum weight row.
Morey also gives a rough check: held in front of you, the board should reach from your knees to your chin.
What the Mach 7SS is not built for
- Beginners: Morey says the core can be hard for them to control.
- Riders over 170 pounds or taller than 5 ft 9: Morey’s chart puts them on a longer board, and the 7SS comes only in 41.5 inches.
- Cold water: Morey describes the PP core as best for temperate to warm water.
- Riding out of the box: no leash is named, so you need to buy one. See our bodyboard leash guide.

The Morey Mach 7: more sizes and a PE core
For a rider outside the 7SS’s size or water range, Morey’s Mach 7 comes in more sizes. Morey aims it at “intermediate & progressing riders” and sells it in 41, 42 and 43 inches. It has a polyethylene (PE) core, which Morey says works best in “cool to moderate water temperatures”, one REX stringer, an NXLPE deck, an HDPE slick, graduated channels and a crescent tail. Morey’s chart gives 170 to 210 pounds for the 43 inch board.
Morey says the Mach 7 does not include a leash either. The 42 inch board’s item weight is listed as 3,511 grams (about 7.7 pounds).
Before you buy
- Your weight and height against Morey’s chart: 125 to 170 pounds and 5 ft 7 to 5 ft 9 for a 41.5 inch board.
- Your skill: Morey’s own warning about beginners.
- A leash: neither Morey board here lists one.
Editors’ rule of thumb: rinse the board in fresh water after salt water, and keep it out of hot cars and direct sun. For more on fit, see bodyboard sizes.
