Schaefer Marine

<h3>About Schaefer Marine</h3><p>Founded in 1966 and headquartered in <strong>New Bedford, Massachusetts</strong>, Schaefer Marine has spent decades earning a reputation as one of the most trusted names in sailboat hardware. Whether you sail a small dinghy or a bluewater passage-maker, the brand's commitment to engineering products that can withstand the relentless forces of wind and sea has made it a go-to choice for racing sailors and cruisers alike.</p><p>What distinguishes Schaefer Marine from the competition is a no-compromise philosophy toward materials and design. Every product in the lineup — from travelers and furling systems to cleats, shackles, and mast hardware — is conceived with a real-world understanding of the loads a sailing vessel generates. The result is hardware that performs smoothly under pressure and keeps performing long after less-robust alternatives have been retired.</p><h3>Blocks &amp; Pulleys: The Heart of Sail Trim</h3><p>Schaefer Marine's <a href="/14859-schaefer-marine-pulleys-blocks-200822">Pulleys &amp; Blocks</a> are among the brand's most celebrated product lines. The flagship <strong>M-Series blocks</strong> feature Torlon&trade; rollers and Delrin&trade; ball bearings housed in machined aluminum bodies, delivering a smooth, low-friction ride that sail trimmers notice immediately. The range spans everything from simple fixed blocks to ratchet and swivel variants, covering boats of every size. For sailors looking to refine their sheet and halyard systems, Schaefer's <a href="/14859-schaefer-marine-pulleys-blocks-202394">block and pulley selection</a> offers a variety of configurations purpose-built for efficient sail control.</p><h3>Eye Straps &amp; Pad Eyes: Secure, Reliable Deck Fittings</h3><p>Deck attachment points endure some of the highest stress loads on any sailboat, which is why Schaefer Marine invests heavily in the quality of its <a href="/14859-schaefer-marine-eye-straps-pad-eyes-201942">Eye Straps &amp; Pad Eyes</a>. The brand offers cast and welded pad eyes machined from high-quality Type 316 stainless steel, along with stamped eye straps crafted from Type 304 stainless — all paired with corresponding backing plates for secure, load-spreading installations. Whether securing a block, lashing a line, or anchoring deck equipment, these fittings are engineered to hold.</p><h3>A Full Ecosystem of Sailing Hardware</h3><p>Beyond blocks and deck fittings, Schaefer Marine produces a comprehensive catalog that includes jib furlers, mainsail travelers, cam cleats, snap shackles, Tuff Luff foil systems, winch handles, and mast hardware. The brand also partners with SeaSure (UK) for rudder hardware and the Hawk Wind Indicator range, rounding out an ecosystem that can outfit virtually any sailboat from deck to masthead.</p><p>Standard catalog products from Schaefer Marine are backed by a <strong>ten-year warranty</strong> against factory defects in material and workmanship — a statement of confidence that reflects the brand's long-standing focus on building hardware that lasts. For sailors who demand proven reliability in demanding conditions, Schaefer Marine continues to set the benchmark.</p>

Very good service

good

This kit worked on my 2013 Grand Caravan replacing sprung spring. Saved 65% compared to dealer kit.

Nice job all around

Good, but delivery time not on a par with other vendors.

Fast shipping. Packaged well.

I really would like to have an estimate of the shipping and delivery dates.
