There are a couple of better ways to light drip diesel heaters. We use a metal oiling can (the very old fashion type) filled with methylated spirits. A small pump would put a bead of meths on the tip. Light that with a lighter. Then point it into the diesel pot and give a couple big pumps. It is like a flame thrower, big squirts of flaming meths right into the diesel pool. Pretty much 100% success rate, and no chared tissue residu to clean up afterward.the small pool of diesel I’ve fed into into the burner for pre-heating often extinguishes the small bit of tissue I’ve lit on fire
An alternative Other boats have used for very cold high latitudes (like wintering over) is a propane torch with a quite long metal nozzle (some of them have been custom machine shop nozzles and some others used a fitting designed/sold for burning weeds out of sidewalk cracks). You light this and use it to pre-warm up the chimney (which helps draft and keeps the fire going after it is started) and then just point it at the pool of diesel and ignite. We found the oil can method to be simplier/easier but we also only ever wintered in the beagle channel and not the really cold places.
Yea, liquids and anchors should essentially be sitting on the bottom with just brackets holding them in place. The heaviest things we stowed on the shelves were spare anchor lines (300' x 3/4"). I was a bit nervous about that weight at the start but it held up just fine.I will endeavor to keep the heaviest loads down at the bottom so that nearly all of the load is just pressing straight downward on the hull
Personally, I would not store diesel jugs in the laz. Not worried about fire risk, but about the massive mess it would make if it split or opened somehow at sea. It 'should not' open, but a lot of shit happens that 'should not'. Very hard to clean up, and the smell will be just terrible - would likily make me at least continuously seasick.
Like others above, we also used the 'plastic wrap under the cap' method to minimize spills/drips/smell.
