The garage floor is more of a mess than I would like, but I'll get it better organized over the next couple of evenings. I realized I had not bought all the bottled water we'll need. There were only three bottles in the storage cabinet and we need a total of eight one-gallon bottles.
I drove to the dump and emptied all of the old fuel out of the two gallon tank, which dated back to last fall. I'll fill both tanks, adding oil for a 50:1 ratio plus fuel stabilizer, tonight.
I do think I've found a solution for storing the second gas can by having it perched on the boomkin outside of the hull. Held in place by a large cable tie and a piece of line fastened to an eye strap, it seemed very secure.
I'll think about it awhile before deciding if this is the right way to go. If I am happy enough with it I may make it the standard place to store fuel while cruising.
