If you don’t already know it, Moray McPhail’s Classic Marine website is an excellent resource. There’s an extensive catalogue for all the nice bronze and gunmetal bits and pieces that traditional boats require, including a wide range of fittings for rigging, as well as navigation lights, portholes and lamps, rowlocks and the rest, and there are also boat plans from Iain Oughtred.

Moray’s site offers more than a fascinating catalogue, however, for he has written a series of essential articles on every detail of a traditional boat’s running and standing rigging hardware. Perhaps the most useful to many will be his article Using Wykeham-Martin Furling gears – an Unofficial Guide.
