2018 Sealegs 7.7M Sport D-Tube

  • 25 ft
  • Pontoon Boat

Overview

The Sealegs 7.7m Sport D-Tube is our supersized all-aluminium hulled craft. The 7.7m D-Tube combines the rugged design of our smaller 6.1m D-Tube with the size and internal space of our 7.7m craft - giving you the best of both worlds. 

The sport centre console allows full walk-around access to the entire craft, while still giving you space for all the electronics you need for a trip out on the water. The placement of the inboard powerpack on the transom allows for additional under-seat storage beneath the helm seat, and the tall pontoons give a smooth and secure ride.

The Benefits

  • Single handed operation, removing the need for multiple personel
  • Immediate access to and from the water — reducing response times
  • Embarking and disembarking is faster, safer and more comfortable than a regular boat for both personel and passengers
  • Gain the ability to access places inaccessible in a traditional boat
  • Perfect for tourism, providing a unique experience that requires less set-up and personel than a regular boat
  • Highly customisable platform, allowing the craft to be modified for various applications​

Craft Features

Each Sealegs craft is powered by Sealegs patented Amphibious Enablement System, or AES. The AES, including a fully marinised system of hydraulically powered legs and wheels, is powered by a marinised 22HP inboard engine. This allows the craft to travel for up to 30 minutes within every hour at 7.5kph on land.

​The fully integrated, turn-key package uses the same fuel source as the outboard, and is simple to learn and engage. Over time, the AES technology has improved to allow owners more freedom to use their Sealegs amphibious craft. 
 
 
All Wheel Drive (AWD)
 
The Sealegs Power Steering (PS) system comes fitted with high pressure hydraulic hoses and fittings which result in an easier effort at the wheel - even when under heavy load. In the unlikely event of a failure in the electric power steering pump, the system automatically reverts back to standard manual hydraulic steering.

Power Steering combines fantastically well with the Sealegs AWD system, making new Sealegs craft a pleasure to operate. 

PS Features include:
  • Fingertip steering control
  • High pressure and grade hydraulic hoses
  • Works well with Sealegs AWD system
  • Manual hydraulic steering backup in the unlikely event of pump failure
  • Comes with on/off switch on console for stiffer outboard control on water.
Sealegs Power Steering uses an electric hydraulic pump to provide extra pressure to the steering system. This provides the operator with fingertip control at the steering wheel for a more enjoyable experience with far less effort. The Power Steering system makes three point turns and maneuvering in tight areas a dream.
 
 
Automatic Braking System (ABS)
 
The Automatic Braking System (ABS) is an exceptional safety feature that comes standard on all Sealegs craft. ABS is a land-based mechanical brake within the rear drive motors which automatically activates when:
  1. the craft is parked and the inboard motor is turned off OR
  2. in the unlikely event of a hydraulic transmission failure OR
  3. if the operator activates the emergency stop button on the console*
To support these enhanced safety features, the leg assemblies have been redesigned for greater strength and fitted with specifically designed hubs and bearings. 

In the interests of safety, we have engineered the system so that it can be retrofitted to most of the existing Sealegs customer fleet, so if you own a Sealegs without ABS and would like this system fitted, please feel free to contact us.
 
 
Extended Run Time (XRT)
 
All Sealegs craft come standard with the Extended Run Time (XRT) feature. XRT allows users to run the inboard engine for far longer continuous periods than was previously possible, meaning that the range of Sealegs craft from the water's edge is much greater. Using innovative cooling technology, users can drive on land for up to 30 minutes every hour. At 7.5kph, this provides a terrestrial range of 3.75km.
 
  no XRT w/ XRT
Runtime 10 mins / hr 30mins / hr

XRT Features include:

  • Fan-assisted hydraulic oil cooling - a high performance fan has been fitted to help reduce engine box and exit air temperature.
  • Hydraulic hot flush valve - sends hot transmission oil to the oil tank and replaces it with cooler filtered oil.
  • High temperature warning - warning lights on the dash panel and a buzzer alarm alert the operator if the hydraulic system is overheating. 
  • Additional 45 amp alternator - an extra alternator allows for greater battery charging as well as the ability to run additional electronics.
All of the components required to bring the XRT system to all Sealegs have been chosen to ensure that they are light-weight and durable in the marine environment. This was all done without increasing the size of the engine box. 

With the XRT package, Sealegs International warrants a run-time on land of 30 minutes every hour, with an annual recreational use of 100 land return trips (to a maximum of 20 hours total use).
