Magic 30: how she is built

 
 

The Magic 30 is exquisitely built of wood by Pease Boatworks in Chatham MA.


Wood is a beautiful material, and  a domestic one that feels good up close. It also has the highest strength weight ratio of all the normal (non-carbon) boatbuilding materials, including steel, aluminium and fibergass. It comes in many varieties, each with different engineering roperties, allowing the selection of species to maximize a particular quality needed for a particular job.


Magic 30 uses 15 different woods :

  1. 1.douglas fir--hull laminates and structural beams

  2. 2.white oak--steam bent frames

  3. 3.atlantic cedar--hull planking

  4. 4. sapele --keel,

  5. 5.burma teak--walking surfaces

  6. 6.butternut--interior paneling

  7. 7.mexican bocote--cupboard latches

  8. 8.okume--sub deck

  9. 9. honduras mahogany--interior trim and coamings

  10. 10. black locust--rubrails and cleats

  11. 11. lignum vitae--chocks

  12. 12. sitka spruce--spars

  13. 13. greenheart--centerboard

  14. 14. bubunga--tiller

  15. 15. garupa--fender board


Magic 30’s hull structure is developed from Herreshoff’s scantling rules modified as allowed by her cold molded construction. Her hull is a laminated skin of 3 to 8    1/8” fir veneers  glued over 5/8” cedar planking. The skin is supported an d shaped by steam bent oak frames, themselves supported by longitudinal fir stringers that form the equivalent of Herreshoff’s structural ceiling. Her interior and other heavy concentrated loads are attached to the stringers, avoiding  large localized loads on her hull skin.


Unlike a fine plastic boat, where the builder must build a secondary wooden boat inside the first to covfer the unappealing plastic, every piece on Magic 30 is beautiful in its own right and her structure is shown off as part of her decoration.
