You should be able to right the 5.2 alone as long as you can get the wind to help a little.

I don't use the daggerboard but you could, it supports immense loads while under use so it should hold you.

I keep thinking about upgrading my righting system but until the one I have fails I will stick with it.

As you get better and better at flying a hull you will realize that alot of the time all it takes in 1-2 inchs of line to keep it right where you need it.

This summer I have managed to keep the hull up for 1 minute solid, this doesn't sound like long but it felt like alot longer. That was actually timed by a friend following me.
