Except for size, a small boat is just as safe as a larger boat. In some instances, smaller boats can be even more safe than larger ones. In those instances, a smaller boat will get picked up and tossed by the ocean instead of pummeled by the breaking waves. This is not to say you will feel safer in a small boat, I imagine going through a major storm in something the size of Flirt would be similar to going for a ride in your clothes dryer at home (hopefully on cool tumble dry).
Part of being safe aboard a boat is taking precautions. I am already rebuilding my Sprite to be stronger and more seaworthy, but my building in safety does not stop with mixing carbonfibre into her hull. Made in Sweden, Origo Alcohol stoves get a bad rep as being an expensive and slow way to cook. Yes, Alcohol does not have the energy potential that say butane or propane does, but it also lacks those gases propensity to explode in confined spaces. An alcohol fire can be put out with water, a propane fueled fire is a good excuse to practice your Olympic grade swimming skills.
In keeping with my philosophy of reusing whenever possible. I picked up this very lightly used Origo 1500 on ebay for just $105 shipped. The Gimbals I had to buy new and cost almost as much. Not happy about that last part, but I am still ahead as compared to buying a new 1500 for about $260 and then spending the money on those same Gimbals.
Except for some wear where it says not to refill from the top, you would never know this small stove was not new. I really made out on a good bargain this time around. Now I need to get it situated in Flirt so I can finish up the Port side furniture.
