Too numerous to count, but current upgrade is to add a belowdecks autopilot - NorthStar - to supplement our favorite Monitor windvane and a weak wheelpilot, Autohelm ST4000. One of our best upgrades was the Icom M802 SSB and also the Spectra Catalina 300 -- oh, almost forgot the Spade steel 44 lb anchor and 300 feet of 5/16 high test chain! See the website for a list of all the older upgrades we made when outfitting to go cruising - on the original website, click Prior to 2007.
