So I'm out for the second time this year yesterday. Got in early to 'warm up' and wait for the decent winds. 2 hours later I get back to shore. I've got a broken line, a nearly broken body and feeling like I should've commited Seppuka instead of hitting the water.
One problem is my inexperience. I live an hour from the water but as a kiddie growing up in Fiji I learnt the basics. I can water start (sometimes) and tack. Not yet tried to gybe.
Second problem is my equipment. I know it's not the latest gear but it is slowly improving. I've got a 5.8 sail and a nice carbon 2 piece mast. 2 seasons ago I was taking out a 1980's bambora board until one day I came back in at Manly in 25 knot winds and a couple of the veterans laughed at me (in a good way) and then regaled me with stories of there adventures decades earlier on the same board. I upgraded to a hifly maxx widestyle 305 (pre 04 model probably very pre!) and remember thinking wow, now I'm flying!
So before I make this into a novel, here are my problems. Well at least all the ones I can see for myself!

I've set up the lines at 'normal' lengths but still seem to be straining my front arm a lot.
I'm leaning back and the board starts to plane and next thing I shoot downwind. So I move my front foot forward a bit and lose all that speed.
Lastly, why is it so hard to put my feet in the straps. My back foot is in the right area but my front foot is always too far forward. As soon as I pull that foot back I'm heading off course again.
Any suggestions would be appreciated. I'm sick of feeling like a cat in a washing machine
