Break your outhaul, and you can retie it in a minute.
Break your downhaul, it will take several minutes of fuss but you'll be able to sail back to shore.
Futzing with the gear in my van one recent windless day I spotted the nick in my inhaul. Closer examination revealed that it was not minor. So out with the heat gun and a brand spanking new downhaul line and I'm back in business. If only there was some wind.
When was the last time you checked your inhaul? I check mine regularly, and have no idea when the line was damaged. Check yours!
