I think you are wrong: This is probably the only of the suggested setups that
- could work (sufficient throughput at low pressure)
- super cheap ($20 range) and
- not inherently dangerous (other than the normal dangers of scuba snorkeling), i.e. oil free
Of course it is not going to last forever, but so what? Buy three, you need dinghy pumps anyways. If it fails, you just surface.
How in the world is the hose going to kill him again?
And of course you don't use duct tape to to attach the snorkel; you use cable ties!!
