UK aluminium boat dealer

The aluminium fishing boat specialists — Portsmouth.

All Heart Marine UK is a Portsmouth-based dealer specialising in aluminium fishing boats and commercial catamarans. We supply the BL650, TH750, LH788 and TideRunner 700 — four models built from marine-grade 5083-H116 aluminium alloy, UK-specified for British coastal and offshore conditions.

Whether you call it an aluminium boat or an aluminum boat, the material is the same — and the advantages over fibreglass (GRP) are consistent. No osmosis. No gelcoat repairs. Stronger at equivalent weight. Fully recyclable at end of life. Trusted by coastguards and commercial fishermen worldwide.

Our boats are serious alternatives to fibreglass wheelhouse boats from Arvor, Quicksilver, Jeanneau and Merry Fisher — at a more accessible price point, with a longer service life and lower total cost of ownership. Read why aluminium is better →

Why choose aluminium

Built for the UK — not the Mediterranean.

Fibreglass boats are designed around fair-weather cruising. Aluminium hulls are used by coastguards, military and commercial operators worldwide because they simply last longer under hard use.

  • No osmosis, ever
  • No gelcoat repairs
  • Stronger at the same weight
  • Better resale value
  • Repairable with any welder
  • 30+ year hull life
  • 100% recyclable — no landfill
  • No antifouling chemicals needed
  • Cleaner to manufacture than fibreglass
Read more vs Fibreglass
The honest pitch: Aluminium boats cost more upfront than entry-level fibreglass. Over ten years they cost significantly less. No osmosis treatment. No gelcoat work. A hull that takes a knock and keeps going.
