I have never used an Argo, but reviews and comments seem to suggest it's not as powerful/potent as the other Arizer portables.
I will also say the air SE is quite a significant step up in performance from the air 1.5 I have used for years. I was very surprised!
DV and IH sounds like a winner but more things to manage and bring is a consideration -including spare batteries? A DV is indestructible but how expensive is that IH and how might it cope with a spray of water?
Something with dosing capsules and integrated mouth piece sounds perfect -as it's avoiding reloading in the wind or rocking boat you really want to avoid - plus extra durability if dropped.
Disclaimer - I have never vaped on a boat but base this info on skiing and playing Cricket.
