Fiberglass is increasingly making its way into the latest versions of pontoon boats produced by the industry’s leading makers, but the Sylvan M5 LZ DC arguably takes the trend to new extremes. At first glance, this is obvious in the sleek molded fiberglass panels that replace any hint of the old standard-issue aluminum fencing. Forward, fiberglass extends around the front corners of the bow and continues down onto the bow deck, even wrapping out and over the tip of each pontoon’s nose cone. Amidships, fiberglass forms two raised consoles, each capped with its own unique and protective raked windscreen. Aft, fiberglass completes the perimeter enclosure, wrapping around dual lounges with aft-facing seat backs and continuing to extend down the length of the deck platform. Occasionally, it can seem purely for aesthetic value; each console features a slender, swooping horizontal arch that wraps around the occupant and extends down the fence side. At other times, that fiberglass’ function has to be revealed. Pivot the aft portside bench backrest over and an optional sink rotates into view, complete with faucet, Corian countertop, and wine-bottle holders below.
