Thanks for all that Leroy. A good diagram by the way. I can see why you would want to copyright it.
I had considered the bars around the canopy. I have my cnopy 'permanently' fixed to
the tub. Very neatly done with black selastic all the way around and it looks like it belongs and is pretty dust proof.
I could remove it, install the bars then re selastic it, but that would make the bars a permanent fixture. That would be a pity on such a pretty 4B; LOL.
My canopy is rated to carry 100KG, so weight is not a real issue, but the shape of the canopy is. The furtherest apart I can get bars on the canopy is 750mm, not far enough for a 3.5M boat.
Looking at your vehicle
pic above, I have similar rear protector bars at the rear. I plan to put some bar work up, supported from these. This will take the back of the boat, and it's full weight when loading and unloading (and will have rollers to make it easier). I will then have two bars on the canopy as
well. The three bars will be about 750mm apart.
My bars will be a bit higher than yours. I have 80mm legs on the canopy rails, plus the bar, so gunwhale will be about 100mm above the canopy and the handle will be about 130mm above the cab roof, given shape of cab.
Interesting that with how far back you carry the boat, you still tie it down to the bull bar. I'd thought this might not be necessary as the boat will not overhang the windscreen and should not geot a lot of uplift from air rushing up the screen.
I haven't built the rear bar yet (but have the canopy bars). I'm fiddling with the idea of incorporating some rubber like engine mounts into the rear bar set up to take up any movement, but I'm not sure how practical or necessary that is.
But having seen your set up now (no support from cab) and the fact you got stress fractures has me thinking. Your front stress fractures would (I asume) be from tying the front down too tight to the bull bar, then getting flexing over the length of the chassis and in
the tub. I also assume you had both sides at the back tied down tight to your rear step to cause the rear fractures?
It is your rear fractures that has me concerned and thinking aout some rubber in the mounting system.
Thanks for you input Leroy.
