The situation as I see it in crude business terms is this:-
I, as a business, contract with my suppliers to purchase their goods/services and sell them to my customers. I have made some incorrect assumptions about sales, with the result that my overheads are greater than they should be in percentage terms. Rather than try to pass on the increase in my costs to my customers, I will try to blame the suppliers and get them to reduce their costs. At the same time I will try to use my customers as "emotional blackmail" against my suppliers to get them to agree to reduced prices for me.
My suppliers won't play ball, so I try the new technique of going bust and starting over. I try to encourage my customers to transfer their allegiance to Newco and just hope that the suppliers will play ball. At the end of the day I'm not really bothered because I haven't really lost anything by trying it on.
Speaking as myself now, I'm personally very sorry indeed for any innocent moorers who are caught up in this, but as has been said elsewhere the way the world works there is always a strong case of Caveat Emptor in any transaction like this. IF the marina are effectively subsidising their costs by a plan to go bust and keep their prices down to retain custom then that stinks, both from the point of view of CRT, the rest of us, AND the moorers involved. The question of whether this marina would have to charge double the price of any other to stay solvent is unfortunately totally irrelevant - that is simply business today.
