Stacker belly strap question
Posted by: korey99 on Apr-22-13 9:49 AM (EST) Category: Kayaks
I'm having problems with the belly strap on my stacker setup slipping off, and wanted to see if I'm doing anything wrong.
I just put a Malone stacker on my TracRac on my pickup. The bars are huge, and they're ~6 feet apart. In the past, I've only carried two kayaks deck down on foam blocks, but now I want to carry four. They're all 10 foot recreational sit-ins, around 29-30" in width.
I put the first two boats up, with the foam blocks and two straps each (through the hole in the stacker, over the boat, then around the crossbar, as described in the manual). I put a belly strap around the widest part of these two boats and cinched it down, followed by retightening the other straps. I put on the next two boats the same way. I added another belly strap around all four boats and retightened everything again.
That 2nd belly strap keeps slipping off. I can see why. It's at the widest part of the boats, so if anything can jiggle at all it'll migrate toward the narrower parts.

Belly strap probably not necessary|

You should only need two straps per side. Here's what I do with whitewater boats and a vertical stacker system. Should work similarly with 10 foot rec boats.

Are your bars as far apart as mine? Since the stackers are so far apart, the boats are considerably narrower at that point. I have done snub lines a few times, but there's less than 2 feet in front of and behind the crossbars.
may just have to test it|

I had bars about 5.5 feet apart on a truck I used to have. No issues with 7-8 foot boats on that setup, but the only way really to tell is to try a test mounting. Strap them on good and tight front and back, and then try yanking on the boats, pulling on the straps forward/back from the top, etc. to see if the straps will migrate off the tapered ends of the boats. I did run into that sort of issue with short, highly rockered canoes on a canoe trailer with an 8 foot or so bar spread. The typical belly straps would just sort of flop off the curved ends of the boats. Ended up having to tie those particular hulls on by their grab loops instead.

I'm OK with the main straps that go over through the stacker. Though if my boats were any short I'd have problems. It's just the belly strap. I don't see how that can ever work, since it's free to migrate when installed as specified.
Not sure what they were thinking|

I just looked up the manual for the Malone stackers, and I don't see any way that "safety strap" setup wouldn't slide and come loose, unless it could be routed behind a cockpit coaming or other raised bit on the hull.

If I have it right, you are talking about a strap that goes around both boats on a side of the stacker once they have been separately attached via straps to each stacker. Do I have this right?
All boats are independent|

Yes, the outer boats' straps thread through the stacker and over both boats, and loop around the crossbar. It's not dependent on the inner boat.
Bow and stern lines|

Bow and stern lines|

The reason I heard you must have your lines either both running in, or both out, is if they both pull forward, there's nothing to counteract that force, and it will tend to migrate the boat forward. Likewise if they both pull backward.
There are 2 different lines of thought|

Two lines of thought regarding bow/stern lines.
Ok - would this work?|

I stand corrected - I did not realize that the boats were over your truck bed.
I think I understand|

I experience something similar while carrying two ww playboats on top of my car

Yes, you've got the problem understood. I don't have anything on those boats to thread through. Perhaps I can rig something up like you suggest, though, or use the loose end of the other straps to secure that belly strap.
