Cabin Boats

Exploring the water since 2003

Shelter Marine is a boutique boat building company specialising in uniquely designed and custom crafted vessels. Our passion for boats and the water is reflected in our designs and workmanship.
In 2016 we designed and developed a European Sloep / Sloepen, christened ‘Merlin’.  With a fibreglass V shaped hull and moulded fibreglass bulkhead, her vintage lines and spacious cabin make this cabin boat great for mini waterborne vacations or fishing retreats.  Being easily trailer-able you have the flexibility of visiting new waterways for a long weekend and waking up to ever changing scenic views.

A modern take on a classic boat

Made from premium high-tech fiberglass materials and workmanship to ensure the final result remains pretty much maintenance free whilst satisfying the unique vintage design. The layout maximises space to ensure comfortable overnighting for a family of 4.  Emphasis on driver experience makes for seamless moverability so your goal to explore new sights and fishing spots can be achieved with the modicum of effort.  Our Merlin cabin boats are bespoke and we encourage customers to be a part of the build process. You can choose the colour of the hull, cushion sets and other optional extras that will reflect your personality and make this cabin boat uniquely yours.

Key Features


Classic design
Inspired by the famous European sloep boat, that has classic ‘vintage’ lines.

Spacious deck
Comfortably carry 4 passengers with sufficient storage space and living areas to spend a long weekend out on the water

We offer a tailor made approach to clients when selecting the finer details of their Merlin.

Planing capabilities
Generally cabin boats are considered slow cruising boats, but our Merlins hull design along with a bigger hp motor has the capability of getting on the plane.

Supremely crafted
Our pedantic style of building is usually taken to the point of being obsessive.  You can be assured the final product is as close to perfection as you can get.
