The watery and smelly sides of life.
I used the Whale quick connect stuff on my boat Ross, it comes in blue for cold and red for hot. the fittings have been faultless and the ability to disconnect hoses from fittings at anytime with out wrestling with hose tails and clamps is a real benefit
I would go whale or guest, don't get caught on on the pipe sizes. You will need to do your homework, from memory 'clarence water supplies' or something like that was where I got an account and some gear cheaper than normal. This included all the desal gear/filters.
I used Whale throughout the boat. I costs more but is easy to install, they have nylon clips (extra) to fix the hose to bulkheads and after two years not one single drop has leaked out, would never use anything else.

I am building a 13.4m cat that has four outlets
Just a suggestion - it's pretty useless having a hot water outlet more than a say 4 or 5 metres away from your water heater. You'll waste a lot of water waiting for the hot to arrive, and it won't be all that hot by the time it gets there.
Our HWS is very close to the shower, bathroom sink and galley. There's also a head in the opposite hull, a long way away, so I made that sink cold water only.
That said, Whale hose and fittings are excellent. Easy to use and they don't leak.
