I agree, I think the fundamental point is that the tubes need to be folded inwards but there is a propensity for the tubes on a 460 to hang down and they easily catch on those sticking out "shoulders". Then they either get overstretched against them (and see how sharp and rough those edges are on the photo from underneath) or they get entrapped as the hull is dropped down.
Probably, because the 460 has long, relatively thin tubes, they will just hang down in the way. The shorter versions will probably not "roll" outwards in the same way. The shorter length to the bows keeps them from splaying out.
So I have now developed a single handed technique to keep the tubes rolled in (easy to miss them rolling out again when standing behind, lifting the rear section) as I lower it down, whilst pulling backwards! But I'm now happier I can avoid problems in the future. In the below photos, you can see I've smoothed the razor sharp edges of the fibreglass shoulders and use a bungee to hold the tubes in - if I don't they immediately fall outwards and become trapped on those shoulders.
I'm still not happy however, that I have an unused boat with two patches already. I've not yet heard from Steve so either he's on holiday or the email is in the spam but he does need to get some documentation on this! And pass the message back to the manufacturers as it is something of a design fault - it may be unavoidable because of the very useful folding design. But maybe improving the quality of those corners might help.
I don't think many 460s have been sold so maybe not been any problems before but if it does start selling well, he could have many complaints. It is now "out there" as a known problem so customer service needs to kick in to prevent others having problems.
I'm still looking forward to using it though and will report back.
