Description
The Tangaroa Mk IV was a design that evolved from the Tangaroa Mk I, James’ first design for which he drew Self-building Plans in 1965. The Mk IV has more graceful hull lines, wider hull beam, more freeboard over the bunks and a longer cabin with standing headroom, so it is not to be mistaken for the Tangaroa Mk I of which many are still sailing.
