Yes I think thatís definitely one of the reasons however there are nice charters of boats other than benetaus jeaneus, and Catamarans. , which I would consider chartering before a PSC. Tartans, Calipers, HR, for instance.
I like the PSC as a good small ocean worth cruiser if you want a narrow, footprint. The are average speed wise with quality workmanship. Great for sea kindliness and easily singlehanded.
It definitely has a niche of owners like you who are loyal to their brand, just like any other brand. Itís isnít really any more spendy than many other well made brands of similar length. I have never used price as a criterion for which boat is necessarily better. Besides itís what you are looking for in a boat. Charters are more about volume.
Understand I am not disparaging them , my good friend has a 37.
I have personally never know a charter company to offer Tartans, sure some maybe do but don't know of any. HR's maybe but only heard of them in Europe which makes sense given they are based there. Sure there are others but the bulk of the charter fleets are especially configured Bene's, Jeanneau, Hunter, etc. for the charter market so that they can accommodate many incarnations of charter parties. Even a new Tartan 395 is about $450k which is $250k less than the new PSC 40. Let's face it, no one is gunna pay more in a charter for a narrower, less goodie filled boat designed to circumnavigate the world so they can island hop for a week in the Caribbean. I wouldn't. The poor owner who is out $700k for the PSC can never begin to recoup costs. Ain't gunna happen, not that you are guaranteed to with a less expensive boat either.
PSC has chosen to keep the designs unchanged, for as we know, the demands of the sea remain unchanged. They are purpose built and if you are not inclined to appreciate that purpose, they are, in spite of looks, quality, whatever, the wrong boat. The major design shifts have been in response to creature comfort, such as more spacious cockpits, wider transoms for larger lockers for the extra "stuff" and more spacious aft staterooms, plumb bows for more LWL enhancing marketability and comfort but not necessarily better sea handling or worthiness. The real emerging dominant force for charters is the catamaran, and in particular power cats. Let's face it, no matter how you weigh in on it, Cats have better livability, comfort at anchor, space to luxuriate in the sun, shallower draft, private quarters, yada yada. I guarantee if we charter in the islands it's gunna be a Cat. You're only island hopping anyway cuz ya gotta stay within the reach of the charter company. Remember we have a 31 foot Pacific Seacraft. We clearly didn't get it because of her accommodations or price per pound of displacement. We could have owned a much newer, much larger boat for the same price. I didn't say better. It just fits our needs. I single hand much or just two of us and 31 is just fine by me! We actually looked at 34's and 37's and liked the layout better on the 31. Did look at a 40 as well...but we are mortal human beings! Plus we weren't really fans of the canoe stern on the larger models as it already limits space aft on already relatively short on space boats! Gotta love they way they look though.
....so hope the OP can find his way onto one, they do sail themselves (as any proper design should). If we have Interlude trimmed well she will hold course without a hand on the wheel or auto pilot engaged, though we do like having Ray aboard, uh Ray Marine!
oh... a final note about speed, little bits add up and clearly if you are hoping to make time on a passage even a 1 knot difference in speed adds up. If this is a consideration then speedier boats may be better suited for you than PSC's. However sometimes speed comes with the price of discomfort and stress on a rig. We are in no hurry. Rather finish rested than first! Many other boats fit this description as well. Good luck.
