Grudens are great, can be used for any rain fishing and really knock the wind off you. If your wet in Oct- April then you are cold.
I have a set, but they are made by carhartt and they are green so I can hunt in them also. I have the coat too but i have never worn it, It has never gotten cold enough to wear it. I wear a Gortex Military woodland parka generally, it is thin and works.
If you watch the Bigest catch, they are wearing probably long underwear with another layer then a hooded sweat shirt with grudens on top. If that is enough for them guys, then that will work during the worst of weather here.
Footwear, you can get shrimp boots at walmart for 12 bucks, if you want something nicer you can pay alittle more and look cooler. The shrimp boots keep your feet dry and do not have black soles. Alot of non boat owners forget about black soles and show up at the boat with big hunting boots on. I do not care as much as some, but Im sure others might not even let them on the boat. Also big hunting boots in a tight area of a boat are very clumsey and if you step on someones toes that can ruin their day. I broke a guys toe one day, so i know.
If you do not have curtains on that sea hunt, maybe ask for curtains for Christmas.
