On the cover:  Builder Steve Goodwin extensively refit and reconfigured Panope, a 34 (10.36m) 1975-vintage Thomas Colvin–designed aluminum schooner, into an able pilothouse sloop for cruising in the Pacific Northwest. The vessel is shown propped on its beaching leg in Glen Cove, near Port Townsend, Washington, and before Goodwin installed a fold-up bowsprit. Story on page 38.
