"Latrine valley" (YLTV) might be the go.`Although a madhouse on a W/E & sunny day.
Follow the islands closely to YFLI, never be from gliding distance where possible. I've done that trip a few times back in my mad days where SE never bothered me & you won't last 5mins in that water! Take a damn dingy with outboard if ya can!
