Rope around prop and unsuitable anchoring tackle seems to be a common cause to these groundings . I only have 2 lines that could foul my prop which are my headsail sheet lines which are winched and secured when not in use.

It's marvelous the difference a day makes. Actually checking a decent forecast before departing particularly in a cruising yacht these disasters could be avoided.
Just watching the build up to the start of the Sydney Hobart on TV. The commentator keeps mentioning 10 to 15 knots of NE winds for the early stages of the race. No idea where these forecasts are coming from. Early afternoon BOM has 25 to 30 knots for the next 3 days for the South Coast. The line honours boats will bet there before the chance of a change.

If you zoom in close on the photos there is a tear in the headsail and also something wrong with the way the main is furled up so it could be damaged too.
