AVON ripped bow in summer heat

I inflated my AVON dinghy up in the cool morning air. Ran it at the beach. Then left it inflated in the back of my truck. That afternoon I got a text "what happened to your boat!" from my neighbor. Front bow was ripped in two places.

I assume pressure increase in the afternoon heat was too much. Can this be fixed? If anyone could give advice on a product and technique I could use to repair this, my 4yr old would be very happy.

Wow, sorry to hear of this.

You might want to PM Paul Tilley (Tidelbiz) with those pictures and see what he suggests.

Real bad luck. My Zodiac handbook warns a boat inflated in 10degC temps can double its pressure if left out on a reflective surface in strong afternoon sun... particularly darker colour boats.

Where the damage has been done is a really difficult place to repair. Mainly because an inner repair has to be applied before an outer patch panel can be applied. You can have a look at a website I created which has instructions for repairing large holes. That particular repair(on the site) was carried out on a PVC Zodiac, whereas the Avon I think is hyperlon - much harder to repair, different glues and processes.

Here's the link.

While making this repair, I'd highly recommend adding a pressure relief valve.

Wow, that's unusual for it to rip through the middle of the Centre strip like that, with heat it would normally blow out a Seam, was there any damage to that area prior to this?

That's pretty bad. Can a SIB really blow apart like that if inflated in cool weather and then left out in the sun?

Thanks for the links. I'm going to give it a shot. I live in Texas (23C in the morning, 41 C in the afternoon). Yes, I will be putting a pressure relief valve.
