Regards marinas and ccers ,i think that if people cant aford the life of a ccer and all the costs involved then a marina mooring is the most obvious alternative.
As regards marinas i do think that some of the countryside is being lost to vast expanses of landl locked water.
Most of the marinas advertise beautifull landscaped surroundings but they are not accesible to general country lovers that used to walk once where now they cant.
In the napton area you have to stay on your boat now because with the massive projects going on by ventnor marina and calcutt to mention just 2 there are no more country walks except perhaps the odd 100 yds before you hit a wire fence.
Not only that the local roads have been carved up by lumbering trucks( i suppose car tax will cover the repairs)
