We are in Northern Sardinia, Porto Torres. There are quite a few boats out on hardstanding within boat
Also Castelsardo have winter hardstanding. Conveniently located in mid western med, rather than way over to the west! Not sure about prices as we have a 12 month marina berth, but moved from SOF which was more expensive, Port du Gapeau, Hyeres, which is all hardstanding, and cost 300euro per month for 12m mono hull
, althoigh a lot of cats also here.
