Clam 21


Motor away for £37,950

A beautiful launch with graceful lines, the Clam 21 is the ideal boat for exploring rivers & inland waterways. With a cockpit spacious enough for 4 and room down below for comfortable weekends away.

The interior layout is similar to that of the Shrimper 21 but with the absence of the centreboard case she feels like a much bigger boat – the saloon is airy with 2 single bunks, chart table and a cooker with double burner and grill. A separate ‘v’ berth forward cabin with under-bunk loo compartment makes her perfect for staying on board.

With her ballast keel the Clam 21 is incredibly stable and sturdy underfoot. Powered by twin cylinder 14hp Yanmar 2YM15 engine she has comfortable cruising at 6 knots and higher speeds when required.
