Also your boat is designed for the sea, it's ok to use on rivers, perfect even for a fishing or camping trip on a large river... The only thing is it will be tricky to manoeuvre until you get used to it, because it's hull is designed to carry a straight line on the relatively still sea. That's what you found out when it wouldn't straighten up for you. You probably caught an eddie line also. Thats the border between slow and fast moving water.. Eddies are areas of still water along banks or behind boulders.NO MOVING WATER PLEASE!!! Water that deep that is slow moving can still have channels of fast moving water underneath that can be more then enough to pin your raggedy ass to a branch and you will not get out of your boat or back to the surface of the water... It all depends on the shape of the river bed and whether there is bends in the river.. Water moves faster in tight spaces so if there is a channel in the river bed the flow inside there will be much faster.. Also the outside of a bend will be moving faster both of these can easily pin you and drown you.. Seriously brother you are rolling with a black belt that does not give a fuck about your life. There are so many other things... Like for instance if you fall out two boulders side by side on the bed can easily trap your foot and your body will carry you forward and you will not be able to free your foot. Please go to a lake or sheltered bay and learn the strokes.. I can list them for you and share all sorts of videos demonstrating them step by step. It's extremely important you learn this stuff... No I'm not just a worried pussy I know what I'm talking about.. Be careful..
