A 29" wide boat is very stable
on flat water and even with some small waves. That’s how I started a year ago and discovered I loved paddling. A wide rec boat does take a lot of energy to paddle compared to a touring boat, but I think you’ll enjoy the boats so long as you stay off big water, such as any of the Great Lakes or large inland lakes in your area.
Just do yourself a few favors by buying good PFDs designed for paddlers, the lightest weight paddles you can afford, and take a lesson to learn the basic strokes (or watch a lot of videos on the forward stroke - there are some good ones here at Pnet). If you buy the Pungos, flotation bags for the bow would be a good safety factor.
BTW, I live on a Northern Michigan lake, but Lake Michigan and Lakes Charlevoix, Walloon, Torch, etc. beckoned and my first boat wasn’t safe on those lakes. Now am paddling a touring boat, but know it won’t be my last.
I hope your paddling experiences are good and lead you further into the sport. We spent a wonderful six hours Sunday on Lake Michigan (ACA touring class), paddling to an island where the water was a beautiful turquoise and crystal clear. Magical.
