1. A boat lift assembly, comprising:
a first aluminum base member having a central beam portion, a first sloped beam portion, and a second sloped beam portion being longitudinally aligned with one another and having an equal lateral thickness therein; the central beam portion of the first aluminum base member having a first end and a second end; the first sloped beam portion of the first aluminum base member being coupled to the first end of the central beam portion of the first aluminum base member and being tilted downwardly with respect to the central beam portion of the first aluminum base member; the second sloped beam portion of the first aluminum base member being coupled to the second end of the central beam portion of the first aluminum base member and being tilted downwardly with respect to the central beam portion of the first aluminum base member;
a second aluminum base member having a central beam portion, a first sloped beam portion, and a second sloped beam portion being longitudinally aligned with one another and having an equal lateral thickness therein; the second aluminum base member extending parallel to and spaced apart from the first aluminum base member, the central beam portion of the second aluminum base member having a first end and a second end; the first sloped beam portion of the second aluminum base member being coupled to the first end of the central beam portion of the second aluminum base member and being tilted downwardly with respect to the central beam portion of the second aluminum base member; the second sloped beam portion of the second aluminum base member being coupled to the second end of the central beam portion of the second aluminum base member and being tilted downwardly with respect to the central beam portion of the second aluminum base member;
a first v-shaped roller tube being coupled to and between the first sloped beam portion of the first aluminum base member and the first sloped beam portion of the second aluminum base member;
first and second rollers being rotatably disposed on the first v-shaped roller tube such that the first v-shaped roller tube extends through the first and second rollers;
a second v-shaped roller tube being coupled to and between the central beam portion of the first aluminum base member and the central beam portion of the second aluminum base member;
third and fourth rollers being rotatably disposed on the second v-shaped roller tube such that the second v-shaped roller tube extends through the third and fourth rollers;
a third v-shaped roller tube being coupled to and between the second sloped beam portion of the first aluminum base member and the second sloped beam portion of the second aluminum base member; and
fifth and sixth rollers being rotatably disposed on the third v-shaped roller tube such that the third v-shaped roller tube extends through the fifth and sixth rollers.
