can you walk me through what you mean by “frontrunner load bars and yakima towers”? and then what is the point about keeping them (the cross members?) flat?
you are saying you bought reinforced front runner cross members and are using 4 yakima 1A towers?!
You will probably want to keep your canoe flat considering the size, and you will in that case not need the Yakima product I mentioned, which is designed for shorter whitewater boats. If you buy the front runner load bars, all you will need from there is some straps. The towers I mentioned from Yakima are actually called “stackers.” Sorry, I got them confused.
