To determine the center of gravity, both fore and aft and vertically, of the Schooner Porcupine, we convened an accomplished team of friends. These locals included an engineer, shipwrights, boatbuilders, a sailmaker, a rigger, captains, carpenters, and sailors. Using highway scales, tape measures, plumb bobs, jacks, and trigonometry, this was accomplished. The current displacement of the Porcupine was also determined. These values give our naval architect an ‘as built’ starting point for calculations.
