I think it is more an issue of back pressure. I agree that the pressure will be the same without a regulator on a sealed system.
I just know that others that have done it, and I have owned many boats with these "rigs"...and if you reduce the flow/volume in to almost nill, a well plumbed system with adequate hose, fittings and clamps will work.
One boat I bought the PO actually just installed an inline fitting like the ones you buy for $1 to flush your car's antifreeze line. He spliced it in and just screwed the water hose directly up it. It went to the galley water faucet and cockpit washdown. It worked for him, it worked for me, and it is probably still out there working.
I was not reccomending this fix for a long term arrangement, nor would I leave it connected if I left the boat. I would hope that we would have more sense than to leave the boat with the water on...But sometimes people need a simple, quick and cheap fix. Sometimes these fixes don't conform to the almighty boat standards that some require, but they work as long as you are smart about them and have enough sense to know what to do, how to control the situation and knowing the chances you take. I mean I would hope that he and others would go out and buy the proper equipment, like a Par Jabsco Water Pressure Regulator available at West Marine for $25 or so. But not every liveaboard is a Sr. Mechanical Engineer, has a Whitby or a Gulfstar or the $29 at the time to do it right, or for some even a store nearby to buy the equipment/parts. I am sure at some point we have all rigged or reverse engineered some system to get it to work for the time being or for your own personal ne!
eds for as long as we needed it, that is what one of the things that living aboard is all about.
Hell I have been on the hook exclusively for over a decade, living on 23-50 footers. I know how to live out there; and live with, rig or live without all those systems if I choose...haha. But next time I will just recommend the jerry jug or the rain catcher. What do I know about dockside living anyway...haha.
No flames please, I wrote this with a tone of humor and a touch of sincerity.

Adjusting the flow volume won't do it. Your boat water system probably
would blow off most of your fittings almost immediately without a reduction
in pressure. You should already have a backflow preventer at the hose
bid. If not, local regulations probably require one. But in addition, you
need to reduce the pressure to something that your system can handle. I
would also strongly recommend using a sprinkler "timer" which shuts off
after a set number of gallons of water have passed through. If you water
system should spring a leak this only allows that many gallons into your
boat. Put it where you can reset it every time you walk by.
