both heads to black water tank and that gets rid of 2 discharges. Now we're at 13. Both engine and gen could have discharged exhaust above water line. Now we're at 11. The cockpit drains and deck drains could be consolidated and some of them y piped together maybe getting rid of 2 more. Now at 9. Seems like instead of spending a little more time routing hoses they put every hose through the nearest section of hull
Maybe I am missing something and dont see why it was done this way. If I could (which I know is impossible) I would have 2 seacocks. One water inlet for everything and one discharge for everything. I know thats not possible but it would be nice. Keeps it cheap and simple.
I think the main problem is not the number of them, but the fact that they are all in the main hull volume. The superior solution is what Steve Dashew did with his Sundeers -- watertight bulkheads forward and aft, all seacocks in watertight compartments outside of the main hull volume. Now that's really clever.
As to the specific recommendations -- it's easy to design a boat in your head
, second-guessing the real designer
, but in reality none of these solutions is good.
All black water through the holding tank
is very poor if you are in an area (like Atlantic Europe) where 90% of all toilet discharge is directly overboard
. Much better to have the sewage go straight out rather than have it run through pipes all through the boat and into a holding tank which you have to remember to pump out, whenever you're allowed to discharge direct.
One water inlet for toilets rather than two would require running a seawater hose 40 feet from one end of the boat to the other -- a much more dangerous point of failure than an extra seacock.
Exhaust water discharge below the waterline has many advantages, especially for the genset -- eliminates the constant splash of water which annoys people in an anchorage when you're running the genset.
So where are all the unnecessary seacocks so far?
I don't like, however, the fact that deck and cockpit drains require sea cocks, and which you can't even close, to boot (shouldn't close). I'm pretty sure that that is to save the topsides from water stains. Sure would be better if they could run them to the transom, at least.
