Multiple kayaks on roof?

Interesting boat.

You said Ocean Kayaks, not Sea Kayaks, so I assume they weigh about 70 lbs each. That’s a lot of weight on your bars not to mention lifting said boats up on the bars sideways. They would be too wide to load more than two flat. Some have said they use no bow and stern tie downs. No boats should go without them unless short distance and slow speeds. But I even fear that. I have had my entire rack ripped off my roof with one boat and hit the expressway on a rare occasion when I didn’t use them. Thankfully no one was injured. I always use bow and stern lines now. Scares me when I see boats on the road without them.

Interesting boat it is. It’s a NDK Greenlander Pro Sea Touring Kayak - 17’10"’ long and 21.5" wide and weights 57 lbs.
Sea and ocean kayaks are used interchangeably (unless you’re making reference to the company Ocean Kayaks that makes sit on tops). They usually weigh between 40 lbs - 65 lbs depending on the material they’re constructed of (carbon fiber is generally the lightest, fiberglass the heavier). I have two sets of crossbars - 58" and 78". With J-racks I can easily carry 3 sea kayaks with my 58" crossbar and 4 with my 78". I always tie down the boats whenever going a long distance. Transported 4 kayaks from Florida to Lake Superior half a dozen times without any problems.
Here’s a photo of the car and boats heading to Maine.

I have carried four often on my Honda pilot roof with no difficulty. Aftermarket rack system that attaches to your roof rails is best. On my Nissan Armada, I have carried 5 on the roof with no issue. However, not being the tallest guy in the world, I have a small trailer that I had some rails made to attach my roof rack to. So easy to load and unload. It also keeps the kayaks down out of the wind and you get better gas mileage. a small trailer is the best way to tow multiple boats. And with a couple storage boxes in the trailer you have plenty of space for PFD’s and other gear. I have actually had some special load bars made and I can now haul 6 kayaks and I am just under the maximum vehicle road width of 104 inches. Kayaks and a light trailer pull so easy that I even drag it around sometimes with my daughters 4 cylinder CRV. One big camping expeditions I attach hook up the kayak trailer behind my 30 foot travel trailer and pull tandem behind the Armada. With the light weight of the trailer and Kayaks, you do not know its there and they are down out of the wind. I have attached a camping expedition picture showing the kayak trailer on the right.

You should also be wary of any insurance company restrictions. A couple of times a year I drive from New Jersey to Nova Scotia with two kayaks on top of my Santa Fe and I have insurance riders on my auto policy protecting the boats from damage and theft.

It wouldn’t surprise me though that if I exceeded the load rating of my SUV, then my insurance company would easily have a way out of any liability in the event of an accident.

I like this.

Someone like that should be arrested.

I was visiting the Perception plant years ago and saw two vehicles loaded almost to that extent. Outfitters?

My guess is a once a year trip to drop rental boars somewhere. Begs the question of why they couldn’t arrange for a trailer and car capable of towing it.

Reverse Shuttle?

@Overstreet
If a shuttle really an argument for a trailer. That’s what they all use around here.

Celia sarcasim intended. We trailer too. Although last weekend I just added the extra yak in the truck bed.

Many vehicles d/n have an outer front area for tie downs. I use two sections of material, cut to length needed, like tie down straps are made from,. Lift the hood, find a place (hole, not a rusted one) on the body, just under the edge of the hood. Tie them by making a knot and pulling it to tighten. They can then be pulled up so the loop extends to the outside, shut the hood and you’re ready to fasten. When done, untie, raise the hood and tuck it under. Close. NOTE: Ensure, when fastening, they will not get in the way of any moving engine parts or anything that might overheat the material. The back end of my boats are tied to the hitch connection. It’s also wise to use cockpit covers to cut down on wind resistance and save fuel.
To deter some who may be tempted to remove a boat (steal), while at a motel or during a food stop, I place a couple of golf balls in a hatch or the bottom of the cockpit. Makes a racket when they try to move the boat from its perch.
I ALWAYS use tie downs, front & rear. Learned that lesson once, as a newbie, when I picked up a new fiberglass boat. Five miles on the road, the wind picked up and it began to dance a bit. Fixed that real quick! And why would I want to risk damage to my car or boat? When you pass or are passed on the freeway, by a big rig or carry on a windy day, you’ll be glad you did. Also, over time, by not using them, damage can occur to your vehicle. I hate spending money I don’t need to. Also, IMO, folks will know you’re not a newbie.
Paddle on. Have fun.

Yep. That’s why Thule, and a number of others, make under hood straps…

The initial reply about rain gutters not being trustworthy for rack attachment deserves some scrutiny. The rain gutters on full-size vans (not what the OP has, I know) are a stronger attachment point for roof racks than you can find on almost any car roof nowadays. All heavy-duty roof racks made for commercial use on full-size vans (vans of the standard style, that is, since the new European style lacks rain gutters) are designed to attach to the rain gutters, and on those vehicles, the rain gutters are virtually as strong as those found on cars back in the days when gutters were the norm (that is to say, much stronger than anything you can find on a car roof nowadays). Such racks can easily carry a few hundred pounds and in the construction industry they commonly do exactly that (of course, the strongest of these racks use eight points of attachment instead of four).

I doubt that there is any other modern vehicle that’s not a full-size van that even has rain gutters, but in the event that there is such a car being made nowadays, then the comment that rain gutters should not be trusted might be correct in that instance.

Many excellent points in this thread, even for transporting one kayak. Safety trumps everything else.

Best racks are ones screwed/bolted into the roof of the vehicle.
Also keeps the boats lower, easier for loading and unloading.
Spread your racks as far as possible, to avoid bow/stern tie-down’s.
Never use rope, takes too much time to tie/UN-tie.
Remember, the first one to safely and correctly fasten their kayak(s) is the first one at the brew pub, or has the first choice of parking.
If you take too much time, either: You have more kayaks than the others, you are new, and have not figured out the best processes, or are tangled up in your ropes.
If it is dark out, get enough light on the area, so no one is dropping anything.

I drive a R32/Golf vehicle, stock is very low, rack is in the roof, screwed down. Cam straps from Salamander gear. Cam’s are always protected by fabric material. Double loop both sides of the cam straps around the roof rack bars, that are strung around the kayak. Buy a little longer strap for this reason, and/or tying the kayak, down in a windy situation. (tossing the strap to the other side of the car)

I have done 100 mph, w/ 2 kayaks, absolutely no noise from the roof/kayak area at all!!

Who’s going to take a vehicle and screw or bolt in to it for a rack?

@PaddleDog52 More than one person here has done that including some very respected pnetters, Generally someone who drives a vehicle into the ground but there are plenty out there…
