Anyhow, cut to the chase - I still haven't figured out how much air I should put into the main chambers with the Advanced Elements 2-way pump. The manual makes it very clear that I should not over-inflate it or I will break it, and I definitely don't want that to happen. On the other hand, I don't know when I'm getting close to 2 psi.
The kayak came with two types of instruction manuals, one specific to the Convertible in English, and one (or two actually) multi-lingual covering all AdvancedFrame models in multiple European languages. What's odd is that the Finnish translation has in its troubleshooting section a problem that other versions don't have. Translation per me:
Is this correct? So far I have been leaving my kayak in a sort of semi-solid state not being sure how much I should pump into it. When I lift it from one end it will sag from the middle. It floats fine even then, but I'd like to know for sure.Problem: How do I ensure that I don't over-inflate the kayak
Solution: Kayak is inflated so that the whole outer skin is filled. It should not be left with any wrinkles. You can also tell this by the pump: when the pump starts resisting, the kayak is filled up. The floor chamber is filled so that the surface feels solid when touched.
