Any suggestions - which narrowboat insurance?

The contracts arrived in the post today for AREandARE, along with the offer of one year's IWA membership (free) and either two months free RCR (river canal rescue) or three months if we purchase twelve months cover.  ABNB have been an excellent brokerage to work with, and Barry (from ABNB!) collected Barry from the train station the first time he went to see the boat, and then us both the second time - great service!

We have two small challenges now.  One is transferring the money from my Barclays Bank account in time to clear two days before Thursday - I have a limit of £10,000 per day!  I'll give my branch a call on Monday, there's bound to be a way around this ...

The other challenge is narrowboat insurance.  ABNB recommended GJW - but having just looked at their  policy wording, they insist on there always being two 'competent' crew members on board when the vessel is moving if it is over 24 feet in length.  This would mean Barry or I could never move the boat without us both on board?!

We were insured with Haven Knox-Johnston when we owned Northern Pride, but recall having to state a mooring initially (we used the marina where we bought her), and trying to get an on-line quote from them today they're again asking for one.  As we intend to be 'continuous cruisers' (apart from possibly staying in a marina over the winter months), we obviously can't state a permanent mooring.

We'd be very grateful for any suggestions of ways around this, or which insurance company people would recommend ...
