Key Features

The Aquanauta XL is the longer version of our best selling Aquanauta 3.3m Sit In kayak. Customer feedback told us people loved the compact nature of the Aquanauta but wanted extra length for an even speedier, flat water kayak that accelerated quickly, could maintain a nice fast glide, is stable but without being enormous and lengthy, typically associated with Sit In type kayaks.

  • Easily capable of 15km+ adventures, our 4.2m Aquanauta XL can reach speeds up to 14 km/h and will be sure to impress you.
  • Beautiful glide and pace on water to give you that true touring kayak speed and feel, thanks to it's V-shaped bow and sleek waterline.
  • Light compact touring kayak for those who desire speed on the water, but prefer a lighter weight kayak body.
  • Perfect for those who seek a balance between speed and stability, thanks to its 4.2 metre length, flat hull design & a low seated centre of gravity
  • With a long waterline and increased rocker, you will be seriously surprised at it's increased efficiency at higher paddling speeds whilst making it capable in an array of water conditions, including coastal kayaking.
Design & Construction
  • It's lightweight and compact design makes it possible for one person to lift up onto their car roof, easy to carry to and from the waters edge.
  • Foot-Controlled rudder system to assist with tracking in a straight line, with pull cord to pull up and let down the rudder in shallow waters.
  • Made from high-grade UV stabilised HDPE material for the Australian conditions.
  • A V-shaped hull with hard chine, and little rocker, easily cuts through water whilst paired with the rudder system provide for excellent tracking.
Build Quality

The build quality is the best in class, with no traces of air bubbles inside the UV stabilised plastic walls, meaning your kayak is superior in durability and won't crack like brittle plastic kayaks prone to air bubbles, due to poor quality control.

Tested to ensure 3.5mm thickness, drop tested to ensure perfect plastic bond, balance tested for optimal stability, and water tested to ensure perfect seals. So rest assured your kayak will last for years to come.
