For Weather in the med, Ive found VHF
to be fairly useless, The best is either Navtex or the Internet
Forget about Satphones, a good cell phone
will do in most places.
Remember you need good sun shades like a bimini
and often some forward shade when at anchor
or in marinas
, it can get quite hot. Mozzie screens are useful too. Dont just equip the boat just for Biscay , I mean thats just a three day trip and its then forgotten.
Youll find the inner forestay never really gets used either, youll just roller furl.
Id forget about the wind vane
, spend the money
As to cooking
and galleys, you will learn to manage, because you do need to eat!. Try to ensure that the crew in a blow that arnt needed dont stay on deck
, get them into bunks, sleeping reduces sea-sicknesses.
