These hulls are made in the UK to a strong welded design in marine grade aluminium and have buoyancy built in under the seats

The back section of the hull is flat but have a gull wing V design at the front meaning that they cut through choppy water well and leave very little wake. With the broad front they are very stable for many applications, including rowing & canoeing coaching, fishing, small ferry services and as a work boat. They have a higher free board than the Flat Bottom designs and are therefore better in choppy waters than the flat boats, whilst being stable for the size of craft.
