Another nice thing about the master cabin being aft at sea, aside from what's already mentioned, is that it's easier to sleep with "one ear open" in order to ascertain that the crew on a larger vessel, has things well in hand. To pass up "suggestions" to them via an open porthole or cracked
hatch. Or to know when to get up there & straighten things out prior to them really hitting the fan.
Also, while at anchor it's quieter to sleep aft, although this has it's pro's & cons. Some like to bunk forward in order to hear their ground tackle, & to better feel the boat's motion (to ascertain if one's dragging). Although me, if the anchor's hookup is that questionable, I'll be cat napping in the
salon or cockpit.
Plus I too am not a fan of the pitching which takes place at anchor in the V-berth in heavy
weather.
One other perk is that on a lot of
boats, biminis are common, as are cockpit awnings. So if the master stateroom is aft, & the above
canvas is up (which is most of the time in warm places & seasons), then aft bunks are always in the shade.
It's not nearly so common to rig up awnings over the forward half of the
boat, & in fact, one unusually hot Summer, I was visiting home, & had to both tell & show my Dad of the
concept, & he'd been a sailor for 25yrs at the time.
And given the biminis/awnings, you can keep a lot more hatches open, or cracked than you can in a V-berth. Such as when it's raining, but still stupid hot.
That, & if done right, you get the perk of ventilation blowing through the whole
boat, & all of the way over you. Not just what cools your
head coming through the fore
hatch (unless you have a chute scoop).
Plus, traditionally, the forepeak was/is used for
storage of all kinds of
gear. Dedicated racks & shelves are built into the vessel for lines, fenders,
sails, outboards, etc... & in a "truly"
seaworthy vessel, a workbench with dedicated vise.
It keeps the wet & smelly
gear out of the living spaces, plus allows for a chain locker a good ways back from the bow. If you look at pics of a lot of the
classic aluminum racers from the 80's, you'll see what I'm referring to. There are a few on
www.yachtworld.com Just do an advanced search with the key categories being;
aluminum, &
racer (as in sailboat).
Or if you take the time to look, go on to YouTube, & look up Skip Novak's "Pelagic" (actually there are 2 now). It's a metal expeditioning vessel designed for high latitudes, & thus a far greater deal of self sufficiency than is common.
