I am 12 as Im sure most of you know by now since i have posted plenty of these things.I have once again been let down, as the NSP fish 6.4 board could not be found anywhere for a suitable price in my area. I have found some more boards that look okay, but im really worried they're gonna be too thin, and i wont be able to stand up without falling down. I am 167 cm, 50 kgs. The board ive been renting is 20 7/8 width, and 2 something in thickness. There are plenty of boards in the range of 6ft to 6.4 but a lot of them are a little bit thinner, and 17-19 in width. I am still very beginner, but i can now stand up and ride the whitewater waves perfectly, and down the face of the waves, if i can get a wave in the horrible conditions i can now stand up and ride to shore. In these choppy conditions, i havent been able to attempt any turns or things like that.
The waves are usually tiny, when im standing in the water, they usually go up to my chest or lower. Now i am VERY aware i am not ready for the transition from funboard to shortboard, but right now, we are not in a situation where we have money to spend on these 3000 rand custom boards or those other expensive ones. I found a local shop, where they sell second hand shortboards for under 1000 which is what i need to convince my parents to buy it.
I live 5-10 minutes from the beach and can ride there whenever i want- which means there is no limit to the amount of practice i can put in. Do you think i will be eventually able to ride these boards, or will i just wobble and fall over. I know i will need loads of practice and wont get it for a while, but my question to you is, IS IT POSSIBLE. and if so , how long will it take if i practiced 2-5 times a week?

Please answer soon, Im desperate to get back in the water!
note: the boards are mostly 6.0 - 6.4 performancy boards and i dont know any tricks or cutbacks and can hardly even turn....
if you think it will be possible could you also tell me the best dimensions to get from those limited shortboard ones.
