Type II is only required on boats 66'+ LOA
Vessels under 66' may use a Type I as defined in 140.3(a)(2):"In all other waters, Coast Guard-certified marine sanitation devices installed on all vessels shall be designed and operated to either retain, dispose of, or discharge sewage. If the device has a discharge, subject to paragraph (d) of this section, the effluent shall not have a fecal coliform bacterial count of greater than 1,000 per 100 milliliters nor visible floating solids."The CFR makes no mention of which device is legal on what size boats...Coast Guard regs do, though--the same Coast Guard Consumer Fact Sheet #13 Vic referred you to. As for "raising hell" with Raritan about your local dealer, Raritan doesn't have "factory authorized dealers'...any boat store or yard who wants to sell Raritan products can do so. It's up to the yards and retailers to know what is and legal in their own local waters. It's not Raritan's fault that he doesn't know any more than the average kid at West Marine or BOAT/US.If I were you, I'd get a copy of CG Fact Sheet #13 and mail it to that dealer with a note attached suggesting he read it before he drives away any MORE business...'cuz he's lost yours. I can't help wondering how many other kinds of products he's giving people bad advice about.There have to be at LEAST dozen yards in your who will happy to sell you a Lectra/San AND install it correctly--something I doubt this idiot knows enough about it to do either.
