Good Luck to Yarramundi in getting the package of repair materials in short order.
Also, in keeping the boat sound with limited leaking until all is well.
I just went to his blog--and it looks like they will get their needed package on June18 via the ferry if no other quicker option comes through. Also seems that they have a welcome to stay there. And a lovely location. And, not at high cost.
All-in-all, it sounds like they will have a great time if they end up having to stay there for this one month period (though they will feel very stressed until they can do the repair to the boat, for sure). While many people cruise with a "schedule" and don't like deviating from it, sometimes you just have to go-with-the-flow. Often it is the odd-ball mishaps which provide opportunity to stay somewhere, get to know the people, and have an unexpectedly good time.
PS. For those who haven't gone to his blog. It is a serious repair he must do. The flow of water is now very low at 1liter/2hours but the worry will remain.
