The North Sea 29 is acruising cutteroriginally designed for sailing in the rough North Sea. She's a substantial boat that should prove a very capable ocean cruiser. She offers excellent stability and the promise of good performance, while the centerboard will make it easy to escape crowded anchorages or explore shallow cruising grounds. Plans for theNS29 include computer generated offsets with no lofting needed. No building molds are used — four laminated ring frames plus bulkheads provide the mold over which the strip planking is fastened. The strips are then covered by two layers of 1/8"/3mm veneer.
A Bermudan rig is available as an option, as is a steel ballast box that simplifies the ballast pour. Beckon, the first NS29 to be launched, is off cruising (in Mexico as of early 2021), and another boat is building in Belgium.
