The MAHURANGI 5.1m to 6m is a lapstrake ketch design with the same basic construction as the Okura. There are two 1828mm bunks in the cabin with full sitting headroom. The hull shape is fairly flat amidships with only 8^° deadrise which ensures the craft is extremely stable.

The plans include FULLSIZE TEMPLATES of the frames, stem and transom plus detailed drawings on hull construction, rig etc. plus written instructions. The plan is in metric and imperial.
