Researching stormy weather in a dinghy

I found some interesting reading about dinghies in heavy weather. It's the bit after heaving to doesn't work. What happens next?

This has some interesting tips

In the meantime, Arwen has new elastic securing straps. The large white fenders bought at a boat jumble recently have been secured low down on each side in the for'ard part of the cockpit. The lockers in the central thwarts have been tidied up. All the safety gear bar fire extinguisher has gone into starboard locker. In the port locker is found all the tools and maintenance bits and pieces. The flares canister has been secured, along with first aid kit under the aft starboard side deck.

There is space on starboard side to secure a waterproof rucksack behind the elastic straps. The spaces under the front deck on top of the forward thwart are now empty.....and will take clothing, bedding bags and cooking materials when camp cruising. 

Things left to do

- move the anchor and its warp out of the anchor locker on the bow into a tray which will be secured to the floor on front starboard side of cockpit when making extended coastal voyages

And repair my rudder. Somehow, I don't know how, it has managed to get a 2" chunk out of the rear of it. Significant damage. It will need sanding and reprinting rapidly. Irritating! I suspect it had something to do with my accident grounding a few weeks ago at Salcombe.
