Strongly recommend everyone carries a puncture repair kit for emergencies.
Back in August this year, en-route between Kirkwall, Orkneys and Amble, Northumberland, Mr. Garside in Magellan Alpha developed a major puncture in his bow tube. Rip was L-shaped, about 1 inch by half an inch. Impossible to "part-blow-up-and-run".
We diverted to the nearest harbour, Peterhead, about a 20 mile run, with the bow held as high as possible.
In Peterhead, Mike stitched the tear with a sail-repair needle-and-thread kit, roughed the tube and patch with sandpaper, applied glue (pause for quick coffee), and stuck patch and tube (pause for reflective fag). Finish coffee and continue to Amble.
Total time in port-less than an hour.
If he hadn't been carrying those simple, small, lightweight, low cost items, it would have been an overnighter and a day lost from our schedule.
PS As far as I am aware the patch is still holding.
