Ear plugs - plenty of more luxurious yachts run their generators a lot of the time. Former FTW racing yachts are open plan so talk travels and they are generally noisy.
Face mask - for a decent sleep in the day
Alarm clock or clocks - being late on watch is a capital offence
Pro Plus / sleeping tablets - and hope you never have to use either
Low-dosage general vitamin supplement - after twenty days on tinned/ processed foods they'll do no harm.
Plenty of books/ tapes/ batteries for your Walkperson.
Some unusual herbs/ spices to make whatever you cook a little different
- food takes on a remarkable importance on cruising yachts on a long and fundamentally boring passage
A book on the basics of astro-navigation (plus a plastic sextant unless you are certain that the skipper is happy for you to use his/hers)
forget monopoly and try Hotel, possibly the best game ever. Also:
(a) 2 packs of cards
(b) Tweezers and nail clippers
(g) I like lavender water to get rid of nasty smells (diesel, heads, unwashed crew). It’s also great on a damp flannel for headaches.
(d) A can opener (just in case)
(c) Loads of sunscreen and after sun
(d) A really dull book to help you sleep and some fantastic reads to keep you awake. I recommend Riders and Rivals by Jilly cooper (yes they are trash but very unputdownable)
(e) Ear plugs and those eye cover things that help you sleep during the day.
(d) Tiny bikini (It's the ideal opportunity to get minimum tan lines as only a few people get to see your wobbly bits)
(f) A decent selection of CD's.
(g) As some one else said…. clothes and then get rid of half. Skirts and boats don’t really mix. Flip flops are too slippery and flimsy for the boat….go bare foot or get some Jesus sandals.
Boats and barefoot don't mix - not if you are at all fond of your toes. Broken ones are easily acquired and little to be recommended. I'm not sure quite how far the duties of the boat boy extend......but for anything involving any form of vertical locomotion - shoes rule.
