1. A fin assembly, comprising:
a mounting base provided for permanent inclusion in a watercraft and bonding with the watercraft, the mounting base having a cavity therein, wherein the cavity has multiple inner wall surfaces and an opening exposed at a surface of the watercraft; a socket base mounted in the cavity of the mounting base through the opening, bonding with the mounting base and defining a recess; and a fin including a spigot inserted in the recess of the socket base; wherein, bonding strength between the mounting base and the watercraft is greater than that between the mounting base and the socket base so that the socket base is detachable from the mounting base upon application of a force while leaving the mounting base attached to the watercraft; the socket base further comprises multiple teeth formed along an outer side surface thereof, each of the teeth having an oblique surface and a horizontal obstructing surface, and the mounting base further comprises multiple grooves formed along the inner wall surfaces of the cavity, each of the grooves forming a horizontal surface, and wherein the oblique surfaces are defined to guide the socket base smoothly into the cavity of the mounting base, and the horizontal obstructing surfaces are defined to abut against the horizontal surfaces so that the socket base can be engaged with the mounting base with the teeth being lodged in the grooves.
