Done right and made right, Propane is a very useful boat cooking fuel.
You are correct that propane is a common and useful cooking fuel in boats. However, I'm not aware that the technology has come a long way in the past 15 years, and even if it had, it's nowhere present on this stove.
"Done right" would not by most knowledgeable definition include this stove.
I'm not an expert in this matter, but I know propane stoves properly designed into boats have very stringent design criteria, including outside storage of bottles in specially designed, sealed propane lockers lockers with overboard drains, automatic and manual shutoff valves, sealed combustion chambers with overboard drains, etcetera.
Backpacker stoves have no place inside a boat with a closed cabin.
The fact that propane explosions are less common than gasoline explosions is not a recommendation for propane.
