I’m considering hanging 3 kayaks from my garage ceiling along with 4 bikes. The garage interior width span is 21’-6” and the total weight of the kayaks is 165 pounds (61lb/45lb/59lb). The bikes are already hung from the roof side by side about 2’ from the wall. The kayaks will also be side by side, hanging lengthwise. I’m not too concerned about the bikes (less than 200 lbs.) hanging within 2’ of the wall, but should I be concerned about the additional 165 pounds testing the trust strength? Would fastening a 2x6 catwalk onto the trust joist about mid-width in the attic make any difference in helping with the support and overall trust integrity?
