Yes, some sampan have no guns, some have a 50 cal machine guns, some have a 20mm cannon. This not new, but has been there all along. Do be careful around them. As for stormy weather, we did bump up the wind speed, but I do not recall the setting now... but yes, you can man the gun in some foul weather, but not the worst. This was due to the fact that even in 6ms winds, you could have a wave wash across the deck, and then you and the entire deck gun crew end up back inside the sub. We had an idea to include a "realistic gun weather" kind of mod to turn that up or down a pinch. As it stands, if you have a 40mm AA gun, that can be used rather effectively against a sampan also, so would be your go-to just-in-case solution...
