I haven't seen the book, but I've seen...
...enough like it to know that while some of his 1001 ideas are downright brilliant, the majority are mostly common sense...and some would make any competent surveyor cringe. More bad advice is offered about the sanitation system than any other system or equipment on a boat, 'cuz everyone starts from false assumptions and nobody thinks of it as a "system"--they try to address each part of it separately don't think in terms of the consequences to the entire system. Even Calder--the ultimate authority when it comes to engines and electrical systems--doesn't understand the sanitation system or why something stinks--or doesn't.Bleach is a good example. It's the most over-rated, over-used product on a boat, and is among the most destructive. Yes...pouring it down the toilet will kill odor in the toilet--for a while. But it's also highly destructive to rubber, neoprene and flex PVC (hoses)--iow, all the seals, valves and gaskets in every pump on your boat. It doesn't clean anything...it doesn't dissolve anything...break down anything...it just kills enough--but not all--of the bacteria to knock down the odor for a while. I'd love to know why he thinks hot water is better than cold. Unlike bleach, it won't hurt anything--although it does soften hose which could make it more susceptible to odor permeation, but it's also kinda counterproductive...'cuz it raises the temperature in the system, which accelerates bacteria multiplication...which in turn brings back odor faster...which leads to pouring more bleach and hot water down the head...<sigh> I've also seen people recommend removing the head discharge hose and beating it on the dock to knock out the urine crystals and sea water calcium carbonates that have built up in it--which could have been prevented, along with odor in the toilet bowl, and without damage to the system, with the use of white vinegar instead of bleach. I've devoted 15 years to one system/issue on boats: the sanitation system and odor problems--understanding the inter-relationship of all the parts in a sanitation system, the principles that determine whether or not something stinks, and how to apply 'em...but I haven't written a book yet. I have no idea what this particular author's credentials are, but he has written a book. So I guess you'll just have to decide for yourself whose advice you want to follow.
