What it costs

The cost of shared ownership is a fraction of the cost of hiring or owning a boat of equivalent quality. In a nutshell:-

It costs roughly £1500 annually per twelfth share to keep a 58-foot narrow boat maintained, and also pay licence fees, mooring fees, insurance, management, winter preventive maintenance, savings etc. (see below for more detail).
That leaves diesel, pump-out and gas (each owner pays for these on a holiday-by-holiday basis) which amounts to an average of about £100 - £120 per week depending how far traveled, etc..
On our standard booking system the owner of a (typical) twelfth share enjoys a minimum three weeks' guaranteed holiday each year (including two weeks in the high season) plus additional weeks subject to availability and at no extra cost.
Each syndicate is free to vary the booking system as desired.
So for three weeks’ guaranteed holiday in a year it costs about £600 per week all-in. If you take a fourth week – usually no problem – it’s only about £500 per week. Much cheaper than hiring!
