Would you be paddling from the Vancouver side? I parked at porteau once and paddled across via anvil. We left very early to avoid wind. The waves can get big even after 10-11. It’s a lovely paddle!
I’m an intermediate paddler with paddle canada 2, and I would not do that crossing alone. I brought a radio and wore immersion gear. The winds can pick up fast so best to be prepared.
if I was paddling alone I’d consider ferrying to langdale and kayaking from there. It’s a shorter crossing and still lovely.
