The Cambridge Kayaks Neptune Single Kayak is a sit-on-top design built for rivers, lakes, calm sea and light surf. It weighs just 21kg, making it manageable for teenagers and adults. The deep centre keel gives it a 150kg maximum weight capacity notably high for a kayak of this size and also improves straight-line tracking.
Built from LLDPE plastic (Exxon Mobil grade), the hull is impact resistant, durable and UV protected. The nestable design means you can stack multiple kayaks on top of each other, saving storage space or allowing double stacking on roof bars.
Storage is well thought out there's a water-resistant 6" central hatch between the paddler's legs, a large rear cargo well with bungee, multiple D-rings and 7 scupper drain plugs. A two-part aluminium paddle and adjustable padded seat with backrest are included as standard.
The Neptune has a maximum user weight capacity of 150kg. This is higher than many kayaks of a similar size and is largely down to the deep centre keel design. The keel adds structural rigidity to the hull, which allows it to support more weight without compromising stability or performance on the water.
Yes. The Neptune is specifically noted for its stability and straightforward handling. It is popular with families, clubs and schools precisely because it works well for people who are new to kayaking. That said, as with any kayak, first-time users may initially feel the boat is less stable than expected this is normal and typically passes after a few sessions on the water.
The hull is made from LLDPE (Linear Low-Density Polyethylene) plastic, specifically Exxon Mobil grade material. This is chosen for its impact resistance, flexibility and UV protection. It handles knocks against rocks and riverbanks well and won't degrade quickly in sunlight. Cambridge Kayaks back the hull with a 36-month warranty and components with a 12-month warranty.
Yes. The Neptune includes a two-part lightweight aluminium paddle and an adjustable padded seat with backrest. Buyers have commented that both are of better quality than expected at this price point. The paddle in particular has been praised as genuinely usable rather than a throwaway accessory. The seat can be adjusted in multiple ways to suit different body sizes.
The Neptune is designed for rivers, lakes, calm sea and light surf. It is not designed for rough open-sea conditions or white water. Several buyers have used it successfully for sea fishing in calm coastal waters. For anything beyond sheltered bays and calm conditions, a more specialist sea kayak would be more appropriate.
The Neptune weighs 21kg and measures 263cm long x 100cm wide x 35cm high. It comes with 7 carry handles to make moving it easier. The nestable design allows multiple kayaks to be stacked on top of each other for storage or double stacked on roof bars. One buyer confirmed it fits inside a Berlingo Multispace van as an alternative to roof-loading. Cambridge Kayaks also sell an H-trolley that uses the scupper holes to wheel the kayak to and from the water.
There is a water-resistant 6" hatch between the paddler's legs for securing smaller items such as phones, sun cream and water bottles. At the rear there is a large cargo well with bungee netting for bulkier gear. Multiple D-rings are fitted around the kayak for attaching dry bags or a paddle leash. One buyer reported fitting a 35L dry bag and a 55L dry bag into the kayak for a wild camping trip.
The Neptune is available in six colour options: Jungle Camo, Black Green Fade, Black and White Camo, Blue Black Fade, Light Blue and Orange Black Fade. Colour availability may vary depending on the retailer and current stock levels. If a specific colour is important to you, it is worth checking directly with Cambridge Kayaks or confirming with the seller before ordering.
