Sealegs International

What Sealegs International does

Sealegs International Limited, founded in 2001 in Auckland, New Zealand, with first production in 2004, designs and manufactures amphibious boats under proprietary patented technology marketed as the Amphibious Enablement System (AES). Its craft drive on land via inboard engines powering retractable wheels and transform into high-performance powerboats on water at the push of a button. Available in System 70 (for boats up to 9m and 3,000kg GVW, using a Briggs & Stratton 35HP engine) and System 100 (up to 12m and 7,500kg GVW, using a Kubota 97HP diesel), the AES is also licensed to third-party boat builders through a B2B OEM programme validated by Naiad Design. The product portfolio spans Sport RIBs (3.8m–12m), Sport Alloy aluminium hulls (6.5m–8.6m), and Commercial craft (6.1m–12m), supported by sub-brands Hydrasol, Hydrapak, Electrosol, the Cross Charge™ electric drive system, and the Automatic Braking System.

Revenue is generated through three primary streams: hardware sales of new craft and a pre-loved programme (NZD 68K–145K for used boats), aftermarket parts and certified servicing through a global service agent network, and B2B income from SLG Engineering Services and AES licensing royalties. Distribution is via direct regional offices in New Zealand (Auckland headquarters with four premises including a dedicated Albany manufacturing facility), Australia (Gold Coast, QLD), and the United States (Bristol, Rhode Island), augmented by 150+ dealers and certified service agents across 55+ countries with active partners in Canada, Denmark, France, India, Spain, the UK, Vanuatu, and the US Pacific Northwest.

The customer base spans four core segments: recreational owners (highlighted by Waiheke Island's 210+ owner community and endorsements from Bear Grylls, Sir Richard Branson, and Philippe Starck), tourism operators (e.g., Pennicott Wilderness Journeys' 11.5m Naiad-Sealegs tourist boats), government and emergency services (Fiji NDMO, Malaysian Police and Fire Departments, Queensland SES, Moreton Island Rural Fire Brigade), and OEM boat builders (Naiad Design). The company employs 101–250 people and operates as a private company with no public funding rounds beyond two small Callaghan Innovation R&D co-funding grants in 2013 and 2020.

Core offering

Sealegs International designs, manufactures, and sells amphibious boats (RIBs and alloy hulls) that drive on land via inboard engines powering retractable wheels and transform into high-performance powerboats on water with the push of a button, eliminating the need for boat ramps or trailers. The product range spans 3.8m to 12m across three lines — Sport RIB, Sport Alloy, and Commercial — and the company also licenses its Amphibious Enablement System (AES) to other boat builders and offers precision aluminium engineering services through SLG.

Product overview

Sealegs International is a New Zealand-based manufacturer of amphibious boats that has been pioneering the industry since 2004. The company produces three main product lines: Sport RIB (recreational rigid inflatable boats), Sport Alloy (aluminum hull vessels), and Commercial (professional-grade amphibious craft). The Sport RIB range includes compact models like the 3.8m Luxury Tender (electric) and 6.1m Sport RIB, mid-size options like the 7.1m and 7.5m RIBs (available in standard and electric variants), large models like the 9m Hydrasol RIB, and the flagship 12m Cabin RIB. The Sport Alloy line offers aluminum-hulled options including the 6.5m Cuddy Cabin, 7.5m Alloy, 8.5m Alloy Cabin, and 8.6m Alloy MAX. Commercial products include the 6.1m, 7.1m, 9m Hydrasol, and 12m Commercial RIBs. The company also offers B2B Amphibious Enablement Systems (AES) for other boat builders, SLG Engineering precision aluminum services, and a pre-loved boat program. All crafts feature patented amphibious technology enabling seamless land-to-water transitions without boat ramps.

Scale indicators6 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Yamaha Motor: Global outboard engine and marine propulsion leader and a key Sealegs OEM partner. Comparable as a marine technology incumbent whose engines, Helm Master steering, and dealer ecosystem overlap with Sealegs' customer base, and which could choose to vertically integrate amphibious capability over time.
• Brunswick Corporation: US-listed marine conglomerate owning Boston Whaler, Mercury Marine, and several premium boat brands. Comparable as a large, diversified marine platform competing for end-boat-buyer share, with the scale and R&D resources that small niche players like Sealegs must position around.
• Highfield Boats: Global aluminium RIB manufacturer with a broad product range and worldwide dealer network. Comparable to Sealegs on hull form factor (aluminium RIBs) and on recreational/commercial channel overlap, though Highfield's offering is conventional rather than amphibious.

Emerging players

• Williams Jet Tenders: UK-based specialist in high-performance jet tenders for superyachts. Comparable to Sealegs on superyacht tender and premium small-craft positioning and channels, though Williams' tenders are conventional jet-driven rather than amphibious.
• Lancer Inflatables: New Zealand inflatable boat manufacturer cross-linked with Sealegs and marketed alongside the Sealegs range. Comparable as a neighbouring NZ small-craft builder targeting similar recreational and superyacht tender buyers, with overlap on hull form factors and channels.
• Naiad Design: New Zealand-based aluminium boat builder and confirmed Sealegs AES OEM licensee. Naiad integrates Sealegs System 100 into its own hulls (e.g., the 11.5m tourist boat for Pennicott), making it both a customer and a relevant peer in amphibious-enabled commercial craft.

Direct peers

• WaterCar: US manufacturer of amphibious cars and vehicles (Panther, Python) targeting recreational and novelty buyers. Comparable as a small-volume amphibious vehicle maker, though it is more car- than boat-centric in product form factor.
• Gibbs Amphibians: US-based developer of high-speed amphibious vehicles (Quadski, Humdinga, Phibian) and supplier to military and recreational markets. Directly comparable to Sealegs as a niche manufacturer of amphibious craft, though Gibbs focuses on quadski/jet-ski and wheeled amphibious platforms rather than boat-style hulls.
• Iguana Yachts: French manufacturer of amphibious luxury tenders and day boats for superyachts and high-end owners. Closely comparable to Sealegs' 3.8m Luxury Tender and premium amphibious positioning, competing for the same superyacht tender and beachfront buyer.

Regional players

• Kirby Marine: Western Australian aluminium boat builder that has integrated Sealegs System 100 AES into Naiad-designed hulls for tourism operators. Comparable as a regional commercial boat builder participating in the Sealegs AES ecosystem in Australia.
