As I wear little safety gear, my tack and gybe/jibe attempts are performed VERY cautiously !!!

I don't know, you little booties would be great for a quick gybe step

Joke aside, respect to what you do. I wouldn't try it without a good protective gear.
You may get a dirt motorbike gear. Protects really nicely from the falls, and still very light.
For about $200 you can get the knee/shin protectors, and the vest with the back/front/shoulder/elbow plates.
