Hi! Im a beginner and have been sailing for 6 months or so. Ive been on a beginner board with an instructor my first time and managed planing and tacks reasonably well in 15 knots. After that i decided to buy a longboard for learning and to use as SUP. Bought a F2 lightning 1983 with a 6.4 F2 "fun" sail, looks like dacron and its quite old i think but not a triangle sail but abit more modern. In lightwind im doing okay, the problems start at 15 knots and up. The board turns upwind instantly and i cant seem to get any control of the sail. Mostly wrestling it until i get into sailing position and even then i dont seem to keep a stable heading but loose control or turn upwind or get backwinded. Is there any trick to sailing a longboard in high wind conditions? Thinking of buying a starboard start 141 L and a HSM superfreak 5-6 and a HSM speedfreak 8 for the longboard and the start. Should i just give up on the longboard and just use it for lightwind and use the starboard start in high winds? I live in sweden so alot of chop and small waves, all surfers use shortboards around my place so i cant ask anyone for tips, they just tell me to use the longboard in sub 12 knots.
This is the desired look:

Cheers guys!
