3.8m Tender
The Sealegs 3.8m Tender redefines luxury and performance, combining quiet electric land propulsion with a powerful outboard for seamless water exploration.
Designed as the premium tender for luxury yachts, it comfortably carries up to four passengers while enabling stylish transfers and access to remote bays and beaches. Its rigid aluminium hull, Orca Hypalon tubes, and teak-look deck reflect exceptional craftsmanship, durability, and refined aesthetics.
Featuring Cross Charge technology, regenerative braking, push-button wheel retraction, and up to one hour of land runtime from a two-hour charge, it delivers versatile, high-end performance for every journey.

FAQs
To get out of difficult terrain, traction aids can be used, and the tyre pressure reduced to gain the required traction.
Up or down is acceptable. Should the boats be stored with the wheels down, it is advisable to lightly coat the exposed lift cylinder rods with a lightweight protective oil e.g. machine oil, Inox, fish oil, or similar (as is recommended with many parts of the boat that may suffer from not having regular usage). If the boat is stored with the legs down, it is also recommended to trim the outboard up to help minimise damage to the outboard skeg should the craft suffer a hydraulic issue and lower onto the hull.
Yes, however extra care should be taken. It is recommended that the craft be placed in a cradle and strapped down against this cradle and the transporter to prevent any movement. The hydraulic system of the legs and the hydraulic braking of the wheels should not be relied upon for transporting; a cradle will assist with this.
Yes, oils and fluids and other functions of the boat are not designed to store or operate in freezing conditions, and extra care must be taken with batteries and other parts. This craft therefore should not be stored or used in environments that are at or below 0C / 32F.
Essentially Sealegs craft are designed as ‘day boats’, with the addition of the wheels to assist in the launching and retrieving for easy storing on land when not in use. Therefore, the craft has not been designed with anti-fouling and extra electrolysis protection required of a boat designed to be moored; any boat will quickly deteriorate without this extra protection. RIB tubes may prematurely wearif subjected to continuous abrasion when tied up. Being an open craft, other risks include exposure to rainwater or other environmental events, and with the automatic bilge pump draining the battery to the point of failure. Any boat left moored will degrade considerably quicker if left exposed to the elements, e.g. sun, rain, and salt water. It is therefore a condition of warranty that the craft not be left unattended in the water for any extended period of time.
Hydraulic servicing is not the same as internal combustion engine servicing. It is easy to think of it the same way, but this has the potential to create unnecessary work and cost. Consult the Maintenance section of this manual for a summary of the requirements.
Yes, the battery is charged by the inboard engine. Craft are also fitted with a larger alternator and therefore will recharge the battery faster. Depending on the model outboard fitted, a battery voltage reading is normally obtainable from the outboard gauge set.
If a keypad button flashes red, it means there is a fault with that circuit. Hold down for 5 seconds or until red light stops flashing to reset the circuit. Try the circuit again and if it starts flashing red again, it means there is a blown fuse or software issue. In this case, please contact your nearest service technician.
