I had a 90 Ski Sanger once and I used 750 lbs. across the back seat, 750 behind the drover's seat, and 350 in the front--it was a closed bow and I liked to surf like this guy--check out the link below. Paddling in could be dangerous because with a 6' 1" board, you're close to the platform and I have to really load my front foot up to keep going but I also weigh 180 lbs. My opinion is you need a huge wake to just paddle in. I've seen videos of people paddling in behind a tugboat. Check out You Tube, Inland Surfer and this link. Good luck.
