boonie: "Try putting a twist in those straps, Tom. It's an old outfitters' trick. " +1 Driven cross country with boats and putting twist(s) in the straps is key. |

Straps The canoe rests on top of foam blocks that I also bought from REI. The problem I have is that when I hit about 40 mph, the air flowing across the straps creates such a noise that you can't even hear simple conversation in the vehicle. I attempted to adjust the straps many different ways and just couldn't make them function without a high level of noise. So rather than the straps, I use simple quarter inch rope with a trucker's hitch. No noise at all. What method do you use to secure your canoe? Anyone else try these straps? |

walllee: "straighthairedcurly: "boonie: "Try putting a twist in those straps, Tom. It's an old outfitters' trick. " +3 on twisting straps. Last year, I used a rope and truckers hitch up front and a strap across the middle (and rope on hitch rack for rear carry handle). |

boonie: "Try putting a twist in those straps, Tom. It's an old outfitters' trick. " Yes, this should solve the problem. The technical (TMI) explanation is that the air flowing across the straps sheds a vortex. That is what generates the noise. Twisting the strap disrupts the vortex formation. If you use straps as bow tie downs do this as well. |

Also, I like to use pipe foam insulation on the bars or gunwales. It protects each and helps keep the canoe in place better than larger blocks. |

mirth: " With any square edge cross bars, whether lumber or commercial (as in Thule), wrap the cross bar with 1/8 in rope across the length of the cross bar. Using 1.5 to 2 in. wraps to lower the noise. Same concept as twisting the straps. It kills off the vortex formation, thus alleviating the wind noise generated by the cross bars to a large degree. |

I converted to climbing rope years ago and learned to tie a truckers hitch. I think the canoe can be held tighter using rope. It doesn't make noise and makes it look like you know what you're doing, like your one step above an amateur like me ;-) . |

Thanks for that. I'll be topping two canoes for the Scouts' trip this summer & will try to remember this. |

When I cartop on my wife's Sienna with a factory rack & crossbars that's 4 twisted sections per boat. 6 if it's an Alumacraft or anything else with a pronounced keel. If you ever need to get crazy and build a rack extension out of squared edge lumber you're going to want to round them off to prevent a similar situation happening while driving around with the rack empty, like when shuttling for a river trip. |

boonie: "Try putting a twist in those straps, Tom. It's an old outfitters' trick. " We use same type cam straps different brand. Yes put a twist in them. CB Ps for those reading. Please never use ratchet straps. Nevere ever. They were a huge money maker for Northwest canoe back in the day. Every year Dennis would repair multiple canoes that had hull damage from folks. Crunching their hulls down too tight. |
