Abstract: A modular floating marine dock includes a polyethylene float that defines a top surface. A plurality of parallel walers fixedly attaches to the top surface in longitudinal orientation and with a proximal end extending no further than halfway across the top surface. A splicer attaches to and extends beyond the distal end of each waler in parallel orientation and includes attachment points for another waler. A block fixedly attaches to each waler from below and in transverse orientation with a setback from the distal ends of the walers of a distance substantially equal to a width of half the length of the top surface.
