The Fastensol Narrow Boat Tilt Mount is a semi-permanent, adjustable mounting system designed specifically for solar panels on canal boats and narrowboats. Rather than fixing your panel flat to the roof, the telescopic tilt legs let you flip the panel from port to starboard in seconds — so the array can always be angled towards the sun regardless of which way the boat is moored. When you're cruising, the same legs fold the panel down flat for a low profile and unobstructed sightlines along the roof.

The telescoping leg design lets the panel angle be reversed from one side to the other, so however the boat is moored on the day, the array can be re-angled to face the sun rather than being locked to a fixed orientation.
When underway, the legs retract so the panel sits flat against the roof. This keeps the profile low, reduces wind drag and windage noise, and preserves clear sightlines for the helmsman passing under bridges and low structures.
The GS Universal Clamp pops into the rail and stays in place during handling, then rotates 90° to switch between mid-clamp and end-clamp roles — one part covers both fixing positions instead of stocking two different clamps.
Rails are positioned close to the panel frame edge to maximise both the achievable tilt angle and the rigidity of the assembly, reducing flex and rattle from boat movement and wash.
All four tilt legs are positioned towards the outer edges of the rails for maximum stability under the panel, spreading load evenly across the mounting points.
Rails and legs are built from AL6005-T5 aluminium, chosen for its strength-to-weight ratio and corrosion resistance — a sensible material choice for a system that lives permanently on a waterway.
