Very true Ant about the "cat."
On the occasion that charterers lost the seat from my boat, the spray hood was also torn to shreds, as too was the genoa. During the storm, and before what was left of the Genoa could be recovered, the flailing genoa sheets went over the top of the mast tearing off the VHF aerial and the wind instrument. Eventually in port, but before the storm had passed a short lead on a forward mooring rope to the quayside, which was higher than the deck of the boat, ripped away the forward starboard fairlead. Fortunately it was all covered by insurance, but the extraordinarily high cost of replacing the helmsmans seat resulted in having a rethink on how to avoid losing it again.
