[PSUBS-MAILIST] prop guards

[Sean T. Stevenson via Personal_Submersibles]

I'd be a bit concerned about propellor efficiency given the disturbance to the upstream water flow, but I guess if I were to fabricate something without going to the effort of profiling an actual foil section, perhaps a length of pipe as the duct with three flat bar supports, and some sort of welded wire mesh or expanded metal grate formed over the upstream side - as open a mesh as I could accept. I'd also be a bit concerned about fouling the screen, and if you did happen to suck something in, it will be that much more difficult to clear it again. Double edged sword?
