More boaters is, I would argue, an objectively good thing for a number of important reasons. Boating on the cut is a minority activity but requires the support, via the grant and the commercial property revenue given to CRT, of national government. An increased number of boats and boaters helps with this most obviously by increasing revenue from boaters thus making us more self sufficient but also the more of us there the more people there are with an interest in keeping the system navigable. Other tangible benefits to more boats is more investment in canal based business, boat services, marinas etc and of course boat building.
Yep, there's no overcrowding here at all for miles around.
