Welcome to SAILING Magazine's annual guide to retrofitting and refitting. This month we are featuring retrofits of four great boats. Some of the retrofits were done by our editors over the course of a few years and others are virtual retrofits, using pricing based on actual boats on the market. These retrofits are thoroughly researched, focusing on correcting issues common in each type of boat and in boats of this age and use actual figures for products and projects featured in each retrofit.
