The problem is the gas cylinder being inside the boat. You want to keep the cylinder in a separate vapour proof locker vented over the side.
I believe that there is a US code on this and failure to meet the code will make insurance a problem.
The stove on its own might do the job and at sub $200 is a bargain when compared with a similar Force 10 at $1200 although that comes with gimbals.
I used a Flavell Vanessa on my first boat as a cheap stove. It did the job but I needed new grill and top burners every two to three years. It was enamel and brass.
