Description
Please note: Current Classic Design Building Plans now include the Wharram Wingsail Rig plan sheets as standard, as well as the plan sheets for the original sail rigs.
After considerable experience with the Narai Mk I and II we brought out a new design to get more volume on the same length. The Narai Mk IV has wider individual hulls and increased headroom by raising the decks to the level of the gunnels and placing the cross beams in beam troughs. This is a very sturdy ocean cruiser with many ocean crossings and circumnavigations to its name.

What’s In Our Plans?
In this video, we open up an example of a full set and walk you through the contents – from the large-scale technical drawings to the beautifully illustrated A3 sketchbook that guides you step by step through the build. If you’ve ever wondered about building your own Wharram, this video gives you a real, hands-on look at what to expect inside the plans.
