Now this topic brings up, for me, a whole question of what kind of boating are we doing, when we purchase a Ranger Tug?? Certainly not some white fibreglas, post-modernistic, double V-8, zoom-zoom kind of cruiser, eh? One of the times I meditate on just why I have the boat, is when the brass portholes get to looking ugly, and I need to step in with, not only elbow grease and finger pressure, but patience and serenity. I would guess that those classicly brass portholes---not make-believe, not imitation, but the real brassy thing, with the wing nuts, round screens, and all---those portholes helped to sell us on THIS boat. Because it's authentic, and a Ranger is an authentic boat with a deep nautical flair, harking back to seamanship and workboats of the past century ( er, that would be the 20th).
I think the brass portholes are there, not only for nostalgia, if that's what it is, but to make us Slow Down and smell the roses, or, in this case, the Brasso. For that is what I use, an old rag and the Brasso I used to polish my uniform in the military, those brass buttons.
You can't get all the stains and flaws out; you're not supposed to, for they add character----but every now and then, you get a stretch of freshly cleaned porthole that shines and shimmers in the sun, and all is well with the world. That's my story, and I'm stickin' to it
