After abit of advice please Guys, me and a mate switched from our 2 man inflatable sevylor yukon canoe to 2 old kayaks ive refurbed, there around 20 odd year old fibre glass kayaks and there pretty long aswell, but we found as soon as we tried to come back against the current today on the river we struggled to hold a straight line. As soon as we got any speed we tended to veer to the left most of the time. Now we are both right handed and wondered if it was something in the way we paddled with a double paddle rather than our old single paddle. we tried to check we were each sitting straight and not leaning to one side or something. Im sure theres probaly something on Youtube but you cant beat chatting to an ol' boy with abit of experience
