Most sailors are likely to foul their prop(s) at some time during their sailing career, and it can be quite costly if you're unlucky. I've done it a couple of times now, and hope to avoid a reoccurrence.

Here are my prop fouling adventures and the lessons I've learned the hard way:

Interesting reading scruzin. Not happened to myself ( yet) but son in law purchased about five years ago a 36 ft iron sailer and one of first weekend trips away anchored at north straddie not realising a stern line had fallen overboard sometime during trip and when he reversed to set anchor the stern line fouled the prop. Only he and my daughter on board,no scuba gear, goggles etc. so they took it in turns with a fishing knife to cut away rope .
Took 3 hours.Guess what I bought them for christmas , flippers , snorkel , goggles and a suitable knife.
A hard lesson learnt

Yes I read your article . To be honest I had never heard of one but will show article to daughter and soninlaw tomorrow . Going for a motor on broardwater tomorrow.
