Mid Channel from Bainbridge is a long day in a bigger boat let alone an 11'er. It must have been glass out.You're gonna be fine in that. Just dont be stupid on your days. Everyone talks like the sound is this huge scary place, and for people being negligent it can be but it shouldnt scare you off. I have run an 11 foot whaler from BI to Humpy Hollow, to PnP, and even as far as Mid-Channel. Pick your weather and days, it is no issue.
I grew up rowing a 12' sailing dinghy all around the north end of Bainbridge and up to Jeff Head at times. Caught a lot of fish from that boat and had a lot of blisters.
The shoreline you are going to be on doesnt have huge currents but you will still get carried around a bit. I'd recommend an anchor for your SRC fishing and slowing yourself down along the beaches.
Crab pots like a danielson will get moved by the current and without a depth finder be careful where you drop. 100 feet of rope is suffficient to crab in 80 feet of water. So weight your pots and dont let go of the rope before they hit bottom. We have 10+ feet of tidal exchange and everyone complains about pots getting stolen. Most are just set improperly.
good luck and enjoy it.
