I hate to write this down but at 78 kg and 1.70 mtr body length you should really be able to right the boat with good technique if you use a water bag.

Something went wrong, but I don't know what. Did you climb the rope when the mast came up ? If not then your buttock sink into the water and you are quickly losing weight. If you didn't climb up the rope and your buttocks didn't touch water at all then you weren't hanging low enough initially.

My advice now would be to take the boat out with a crew and do several righting efforts. The crew being there to hold the bow of the boat and help you out when righting fails. Try several things and see where the hang-up is. It may well be very educational to first try to right the boat together and see what works to speed up the righting itself. Most often these are the same points that will allow you to more easily right the boat singlehandedly. I think that experience does hep in righting.

Things I would try is.


-1- Unhook the mainsheet from the sail completely. Now the boom will point downward at the maximum angle and all shape will be gone.

-2- Hang lower, just above the water initially and when the mast comes up pull yourself up a little so you maintain your low position above water when the mast comes up. This trick seems to work well for me. Timing here is key. Wait to long and the mast stops. Climb to early and you may have to hang of the righting line longer then needed. If this is hard on your arms then use a small tackle

-3- Attached a proper bag (one that one rupture easily) to the righting line by its own line. Sits on hull hook on your trap harness and fill the bag. Then get into the water put the bag over your shoulder and push out again the hull. Now the bag is hanging off your shoulder and you've just doubled the leverage of the righting bag relatively to having it in your lap. Have a smaller line attach the bottom of the bag to the end of the righting line so you easy get the bag out of the water after righting.

-4- Also check if there is water inside your mast.

Again, somewhere something is going wrong and finding this is key. You should be able to right the boat.
