It is clear from the weblink that there is significant opposition to the charging proposals.
I took W9755 to Windemere at Easter and kept her in the boat park near the Hawkshead ferry, just S of Bowness. Charges: £10 for one off launching fee, storage £5 / night. (Storage charges are actually £10 / night if LOA > 5m, but the warden calculated to nearest metre). No mention of registration. If you travel to your boat by car you will have to pay £5 / day for parking.
I would hate the hassle of displaying numbers etc, but personally would accept a small increase in charges (even registration, without the big sticky numbers) in return for the disappearance of the speedboats.
