I think the issue is that there is no option, even if nobody buys one. Look at BMW and Merc, each of their models has a low priced stripped, no features base at the same price you could by a top all optioned Ford of similar size. They probably only sell a few of the base models each year, but the option is there if someone really wants one.
Same should be for MC/Nautique/Malibu, the base model should ideally be stripped of features i.e. no bow seats, no interior lighting, minimal seadeck, basic gel patterns/colours, basic screen with ZO, lower spec motor etc similar to when they first released the 2014 Prostar. Each boat is built to order so it's not like they'll have 50 unsold base spec models hanging around, all it takes up is a double page spread in the brochure.
