Yes, I think simple is best, the strainer ideas, especially DIY simple strainer would be preferable, as that way you can modify as required. My shower drains into one of the bilge
areas and is pumped out by one of several bilge
pumps. However after looking at a few of those simple strainer solutions, I may add one. Stuffing around with a whole pump system for shower hair to my mind is a waste of time, money
Not required for myself, as I am follicly challenged, however I am sure it would be handy when guests are aboard.
