Another cause of leeway

A slow steady pedal action will help you gain upwind performance at a higher angle. Especially with an inflatable.

I think about it more in terms of boatspeed. In light breeze with boatspeed low (about the same speed I could pedal/paddle), I can improve pointing by 20 degrees or more by human power. When the sailplan is working so that the boat is moving faster than I can "help" it, I'll take the lower course unless there is an obstruction I can pass if I assist. A lot is experience in your conditions and your boat. A lot also is how fit you are and how much of a hurry you are in.

Surface water current? If the wind has sufficient speed, fetch and duration, you will get waves/chop. That will definitely slow you in a little light boat and provide opportunity for more leeway. Your other scenario when in protected waters has also eliminated fetch so you "shoot upwind".

Seriously, I don't think you need concern yourself about a surface water current causing leeway. If it helps you, though, by all means, invent more reasons why you can't go to weather.
