Laser II capsize recovering solo

Hello,

I want to sail solo on my Laser II, but I am having trouble recovering from capsize (I am 70 kgs) when I go out alone: the boat almost always turtles. I dont want to install a mast float to reduce the risk of the dinghy moving away from me at open sea.

If a stand on the daggerboard and pull de trapeze, the dinghy stands up but continues til capsizing the other side.

Hints please!!
