First sail this year

So yesterday we finally got my wave in the water and sailed. 10- 15 kt winds. And it was fabulous. I just got the trapeze and its a blast. However, we did find ourselves in trouble ( my brother and i ) We were on a reach and a big bigf gust hit us and we capsized for the first time. The river we sail on is pretty narrow and there is a boat yard straight out from my house and a bridge to the left. When it happend we were pretty close to both. I spun the boat around so the wind could help. I grabed th righting line and yay its coming over. Well, i guess the mainsheet was to tight and the boat swund right back over and now was drifting fast into the marina. Luckily a powerboat help us and we sailed on home. Embarrsing, but good expierence.
