So how do you keep warm and dry in the marine environment? It's fairly well acknowledged that women tend to feel the cold more than men do, so that should give you some context for what follows.
Outer kit MUSTO BR1 jacket and salopettes 2014 model (seen here) - also worn with SeaGo harness / self-inflating life jacket. Next layer down - days and warmer nights PYD micro-fleece (supplied by company); cooler nights North Face Polartec jacket, both worn with lightweight capri length North Face trousers. Next layer Icebreaker long sleeve merino vest & long pants over lightweight bra & pants. Icebreakers 200 / everyday grade. Most nights I added a merino gilet - also Icebreaker 260. For the coldest nights (Atlantic) I added a 260 Icebreaker long sleeve merino or a Katmandu merino half zip top - also 260. Footwear - only able to take sea boots (Gill) worn with thick socks most days. Crocs on warm days but they can be a bit slippy for deck work - just all I had at the time, and light to pack. Other things - I wore a Buff tube with UV protection to keep sun off my head and hair off my face. An additional fleecy Buff for more warmth around the neck, and a Buff peaky hat for a change. Gloves - usually fingerless for sun protection in the day and some cheapie Gill grips for warmth at night. If it had been any colder I would have needed thicker, waterproof gloves. Warmer hat and hood up for cold nights were also essential. Merino underwear worn most of the time, even in sleeping bag. On hot days - noon, afternoon watch - I needed to peel off layers not to get too hot - surprisingly easy for this to happen, especially when changing clothes is a bit of a challenge. Sleeping - I only had my outdoor 4 season down bag and this proved a great comfort.

None of this kit is cheap but merino has huge advantages in terms of being warm, not too hot, and it really doesn't get stinky worn continuously. Alternating 2 base layer tops ensures a bit of recovery time.
My male companions both wore the heavier duty Musto BR2's - I tried these on at our local (very) Force Four but felt that the heavier weight was more restrictive. The women's BR1 is well designed - my only criticism is that there are no hand-warmer pockets on the salopettes which leaves the hands a bit adrift when not steering!
I think that's about it - shore clothes at a minimum - denim jacket, jeans, capris from FatFace, T-shirt, long-sleeved cotton top. Had to pack everything into 18Kg hold baggage (extra space for skipper's almanac & tool kit) plus hand baggage. Books - only one plus essential Kindle & audiobooks on iPhone.
Other essentials: head torch for night watch, apron for cooking messy stuff at an angle and keeping grease off clothes, sharp knife in sheath.
Hope this is useful - any comments / questions welcome.
So what happened between the ferry and Marans? Well - there was just over a week at Philippe Julien's yard in Charron - 10 K from Marans. During which time I anti-fouled the lovely Snork Maiden with 3L of Cruiser Uno in smart navy. Marylene drove over from Rosas and the two of us spent a happy few days in a maze of closed cell foam and glue, dealing with a sort of vinyl polar bear skin that is the forepeak lining. Results were better than we dared hope, and although there are some edges that need to be dealt with in due course. The main thing is that the forepeak is now fully functional for sails, baggage, boarding ladder and human crew. Yippee.
