I’ve lived and worked in remote fly in and boat in logging camps on POW for many years. Waders are good, just avoid neoprene. I prefer taller hip boots. I know the big attraction of this hunt to people from Outside is the whole boat skiff thing. I get it. But in all my years working there, most of the bigger bears weren’t killed or seen out on the flats. I know, disappointing. my two seven footers were taken well inland, maybe half mile to a mile. Depending on where you hunt, tides, size of skiff, bad water chop, weather, you may lose time.
Wool shirts, wool sweaters and good cork boots were essential to me.
I’ve only done two SE near hunts, one drop off and one live on board a big boat. This is the exact advice I’d give from those experiences. You need footwear you can hike and climb in. They aren’t all on the beach.
I cannot imagine doing one of those hunts with anything neoprene.
I’ve gone away from wool to synthetic but know how to later either and you are going to be good.
