We do not like cancelling reservations, however if the weather is not suitable we have no other choice. It is stated on our listing all sailings are weather dependant, this means if the weather is not suitable the boats will not bring passengers out. In this case, we offer a full refund on our side however we accept that Air BnB have a service charge of 12% service fee for guests and 3% service fee for hosts which is not refundable. This is why the refund is lower than what you paid. When an Air BnB account is set up this is explained and people should be aware of this. On the day in question the weather was not suitable, however we could only make this decision on the day we had to cancel and we do not bring people out if it not safe to do so. In this case a full refund is given less Air BnB's service fees, which we feel is fair as Air BnB provide a great service.
Sorry for any inconvenience
