Post subject:  Technical Data (screws, mounting point, load)

Hi,

I pretty much read every single messages on this board.

I am currently looking for details that will likely have to come from Hobie Eng unless someone already has these details.

1: The screw specs for the various mounting point options around the hull.
2: The max torque spec for the screws mounting points. (Seeing how many folks complained about the H-Rails, I know 99% of the end-users won't care or spend the cash on torque screwdrivers or wrenches but I'd still want to get these numbers)
3: Now I am going to get technical, are there any data related to "Strength of Materials" shear, load, bend and whatever fun stuff the engineers may have tested. The reason I am asking is simply because I see more and more folks loading their H-Bars or adding motors or upgrading the small skid plates at the back and use longer ones so they can let their kayak rest on it.

All the little upgrades I see are great, but seeing what happened to the H-rails installation. I am starting to wonder how much load can the lynx actually take on these screw mounting locations and I would hope for Hobie to be a little more specific than "just don't over-torque it" or "Don't over load it" if folks are spending 1500$ to motorize their Lynx and another 1300$ on fancy addons and fish finders. I'd think that knowing the limitation and load capacity of the mounting point is probably the best interest of everyone out there.

Hopefully we can get some specs and data.

Cheers,
Ben

Interested in the results as well. The Hobie Lynx H rail instruction video says you can pick up your kayak using the H rails, but many I hear says they wouldn't do that

Yeah, I am quite surprised to hear that guy saying the H-Rails are good to handle the lynx.

I am currently considering trying to take my PA14's seat and try to get it on my Lynx. I'd need to 3D print new receivers for the seat but I am still waiting for Hobie to provide us some technical details.

This guy did it to both his Lynx and his itreks. You could message him, he's also on the Hobie Lynx FB group.

Just joined the Hobie family and forum, and picked up 2 Lynxes yesterday. I am also interested in torque specs. I was going to buy a smaller torque wrench for bicycle anyway. Plan to get the H rails when available.

There are no torque settings for any Hobie products. Not a thing.

So how is a product developed and going through QA and for load ratings?

There is a video out there on the H-Rails stating the rails can be used to carry the Lynx. Yet many customers here and on the Facebook page are livid about the damage on the hull. I presume there is also no such thing as testing products either?

I'd be amazed that non of the mirage drive are assembled to specific torque settings, if so then why charging this amount of money when manufacturing standards aren't at the top.

Well it's all good I won't buy the rails or any other mounting accessories since the hull can't be drilled and mounting points have proven to fail.

THANKS hobie for this greatly "engineered" product!

Test, test, test... that is the way. This is not a high-tech environment. If it breaks... try again until it doesn't.

Is there any data regarding maximum pull force that can be applied to the the embedded t track? With the h rail on backorder, I am loading quite a bit on those rails with a small footprint to distribute the load. Not sure if Hobie does any FEA on their products or not. I really don't want to overload the track and have it pulled out

I have always adopted the view that if in doubt, add a backing plate and if access is not available, install a small inspection port to gain access.

The track is embedded and glued into a foam core board. There is no internal access for backing plate or inspection like a plastic boat.

Try not to load a ton of stuff on the track but it is pretty strong. If it pulls out, you can add filler to any damage and re-epoxy it back in with foam safe epoxy. Just like a hard shell paddle board with its embedded tie down points. Since the Lynx is just a paddle board with a lawn chair, I don't think it is meant to be loaded down with gear like one of those PA's or Outbacks.

Messing with the Lynx offshore in Navarre, I was shocked by the weight of the big fishing kayaks I helped out of the surf. Monsters.
