- - Maybe I should have clarified to say in my real life experiences (one on the west coast
and one on the east coast) the officers wanted to see a padlock. Some other officer might accept plastic tie-wraps. Like checking in/out of a country, the official you end up with may want tons of stuff and hassle you and another official may just smile, stamp your forms and say - have a nice visit. It is all variable. I just don't like getting into a hassle arguing with any of them so I go the most conservative way that will satisfy the whims of all of them.
- - Not having a deck pump out it good evidence to the official that you intend to discharge within the "no-discharge zones." In the USA waters some new marinas
must have provisions for pump-outs at each slip if they are going to have Live-a-boards. This on one of the reasons some marinas
will not accept live-a-boards as it is just too expensive to install all that stuff.
- - There are only a few places out of the hundreds of places you can stop in USA waters that are "anal-retentive" about holding tanks
and pump-outs and if you avoid them then any sort of system will be okay. I just like to configure my boat so I am not restricted in anyway from going to anyplace that my whims take me. The locking Y-valve system covers all contingencies and in 10 years of cruising have only had to actually do it twice.
- - Yes the Marelon Y-valves are a bitch and get progressively more difficult to work. I found a Y-Valve that has a small "half-moon" type handle centered over the valve shaft and it has turned easily now for a year. I would suggest staying away from the Y-valves that have a long "off-center" type handle. There is also a Y-valve that has parallel inlet/outlets and a metal lever that rocks back and forth to switch outputs. In some areas having all three hoses parallel is the only way it will fit.
