located in seaside communities, an attractive female, in her 20's or early 30's who dates/sleeps with unattractive old rich men (at least twice their age) in order to gain access to said men's large boats/yachts during summer months as well as receive other monetary perks. They are much the same as golddiggers in principle. However, whereas golddiggers can be of any age, boat whores usually belong only to the 20's to mid-30's attractive female population. See also trophy wife and sugar daddy.
For her previous night's labors at Viagra-aided intercourse, the blonde boat whore got to spend the rest of the weekend sunning on the deck of the "Inspiration" to the dismay of all the gentlemen callers her own age.
