There are allot of cheap
places to moor/berth over the winter. It all depends on where you want to be. I am tend to try a different place every year. This year I am in La Duquesa (spain). I usually do an internet
search or email
to see if they will do a deal. This year I found my berth by using UltimateBerths.com
it is actually some ones private berth who has gone to the Caribbean
for the winter. There is a fair few listed on the site both from actual marinas and also from private people all over Europe
I am also going to try and negotiate a deal for lifting my yacht onto the hard stand so that I can scrub her bottom.
