Repair of SHARP CHEDDAR

by C. Joe Parker

SHARP CHEDDAR, a San Juan 24, was badly damaged in a storm here in Bay City in November, 1991. The water blew out of the Saginaw River, and the boat bounced on the bottom of its slip for about 18 hours. When the boat was removed from the water a couple of days later, the keel actually wiggled back and forth. The keel to keel boss joint looked fine, with absolutely no sign of cracking or damage. There was little indication of the severity of the damage, but when the keel wiggled, the bottom of the boat flexed in and out. My friend John, who has owned the boat about 15 years, was pretty upset. He was afraid it could not be repaired. Continue reading

The problem of how to restore two tons of decaying whalebone daunted John Smith, curator of the Falkland Islands Museum in Stanley.

Fifty-eight years later, the logistics of restoring the historic monument added up to a whale of a headache. Continue reading

Sure enough, a dab of epoxy finds its way onto your best pants. Believe me, it has happened to me plenty of times. My poor mother grieved with all the school clothes I carelessly ruined in my sloppy days as a kid boatbuilder. Continue reading

How to Loft Airfoil Sections

by Captain James R. Watson

When a designer chooses a foil section for a particular design, that section is often not produced to a close tolerance. I sailed on a boat that was noted for its erratic steering: the problem boiled down to an asymmetrical rudder. Optimization of the airfoil section translates into measurable performance and handling benefits. Continue reading

Durable Edges for Centerboards & Flip Up Rudders

by Jim Derck

When centerboards and flip up rudders drag across the bottom, the first fiberglass to abrade away is usually the leading edge at the bottom. This exposes the end grain of the wood, allowing water to be absorbed the length of the centerboard or rudder. The wood then expands, cracking the fiberglass along the leading edge and causing more problems. When it is time to repair the tip, it usually takes a long time to dry the wood for an effective repair. Continue reading
