A sea perch apparatus includes a platform configured to be located between a pair of spaced-apart sea perch support members located along a side or end of a boat. The platform is designed to be elevated so as to be in an upright position between the sea perch support members and lowered so as to be in a horizontal lower position near a waterline in which the boat is flowing when in the water. The platform serves as a guardrail between the sea perch support members, and when the platform is in the lower position, it serves as a swimming dock, tanning deck and further serves to facilitate easier embarking and disembarking to and from another boat. The platform is transformable into a seat when upright with arm rest. When upright, it is locked in place on either side of the upper side of the platform.
