I would advise considering wearing a light wetsuit under your drysuit if it is really cold. You should always consider the possibility that you might tear the drysuit, which then turns it into a wind/spraysuit really quickly. A tear can also make you very heavy when the thing fills up with water. I have been out of sailing for a few years now and am interested in seeing what gear improvements have been made. I will def be checking out what the kayakers have to offer.
