If you want to go out and buy a toolbox for a boat, either mounted or something portable, what would it be? I keep big, rolling toolboxes at home and at one of my workplaces, and a pretty big box in my SUV. I've recently bought some Dewalt Tough System boxes for my car and boat, they seem as rugged and waterproof as anything I've found. They actually have pressure-relief valves like Pelican boxes, and over-centering latches. I'm not sure if the latches will rust, but the tools should stay dry with a desiccant pack. I like that I can latch them together to tie them down, or separate them for ease of carrying up and down stairs or ladders. I bought one big box for spares, and several shallow boxes for tools. It is always nicer to have drawers, but that takes up valuable space. Multiple shallow boxes allow me to stuff these full and still find tools when working. I bought one clear-top organizer box, kind of nice to see what is in it, but fewer handles and probably not as airtight. I'm still finding ways to organize in them, like putting all my combo wrenches on large D-rings made for that purpose. I looked at Bosch and other waterproof stacking toolboxes, their smaller footprint seemed like a plus, but less rugged, and some bigger tools might not fit. Pelican is a lot of money for what they are, even copies I looked at in China were pricey. I'm still not sold on this brand over the other similar offerings, but impressed.
