The Schaefer Marine video series on restoring a venerable Cal 40 is quite well done.
This episode--the boat is nearing ready for launch--provides a long walk-through of upgrades, solutions and ideas that are likely of interest to anybody wondering what time and resources can do.
The marvelous Cal 40 has had many racing successes and this one will have more still. But it's still an old boat, like ours.
Nearly every issue, from rainwater down the mast to dorade boxes to propane storage, has a direct application to Ericson restoration.
