Esho,
if there are two of you only about 1 in 10 capsizes will end in turtling, and that will mostly be when you are unable to uncleat sails/travellers in time or the wind/waves push you over. The good thing is when the boat is turtled it is really easy to get onto the tramp as it is at water level.

Uncleat all sails, stow the spinnaker and get your crew sits on the back of the hull near the rudder. If you join her or just stand that back quarter of the tramp the opposite bow will come up. Grab your righting rope and lean out and then boat will come back on its side.

If your righting rope is set up at the right length with an eye/ring you put the eye/ring around your trap hook and hike out level with the fwd beam the boat will right itself really easily for anyone who weighs more than 80kg (just ask if you are unsure about the righting rope set up as it makes life really easy when done correctly). The boom will slide out to the end of the track and sheet, and the mast will start to rise, increasing speed as the sail clears the water. If anything it may right too fast and there is a risk of it going over the other way, but holding onto the righting rope in the water stops this.

Unfortunately I am well versed in righting the boat, but having a well set up righting rope and a bit of practise greatly reduces fatigue and you get really quick at it.
