Sea-Dog Line Bow & Stern Eyes

Sea-Dog Line Bow & Stern Eyes: Built for the Demands of the Water

When it comes to securing your boat to a trailer or dock, few connection points carry more responsibility than the bow and stern eyes. Sea-Dog Line has spent over a century engineering marine hardware that boaters and boat builders trust — and their Bow & Stern Eyes are a prime example of that pedigree at work.

The Sea-Dog marine line is celebrating over 100 years as a supplier of quality marine parts for retail and OEM customers. That longevity is no accident. For over 80 years, Sea-Dog Marine has grown to be a premier provider of premium marine, industrial chain, and rigging hardware in a variety of materials including bronze, galvanized, and stainless steel. Their bow and stern eyes reflect this deep material expertise.

What Sets Sea-Dog Bow & Stern Eyes Apart

Sea-Dog's bow and stern eyes are engineered specifically for the rigors of repeated trailering, mooring, and lifting operations. The lineup spans multiple material options and shank configurations to match the specific demands of your vessel.

• Machined 304 Stainless Steel: Constructed of corrosion-resistant machined 304 stainless steel, these eyes include adjustable finish nuts, which provide superior performance over crimp ring-style stern eyes.
• Robust Backing Plates: Robust backing plates add rigidity, and the shanks are constructed of corrosion-resistant machined 304 stainless steel — critical for distributing load stress across the hull rather than concentrating it at a single point.
• Rolled & Cut Thread Options: Smaller 3/8" and 7/16" shafts feature rolled threads, while 1/2" stock uses cut threads — giving installers the right thread style for their application and material thickness.
• Weldable Aluminum Bow Eyes: Constructed from cast 356-T6 aluminum, this bow eye offers excellent corrosion resistance and durability, ideal for permanent installations on aluminum vessels, docks, or other aluminum surfaces.
• Twin Shank Design: Sea-Dog also offers a twin shank bow eye option — a die cast zinc chrome-plated head twin shank bow eye — for applications requiring extra lateral stability at the bow.

Tie-Down Points You Can Count On

Stern eyes are designed for use as a tie-down point on your boat's stern , where forces during trailer transport or rough-water mooring can be substantial. Sea-Dog engineers these fittings to handle that abuse without play or flex. Bow eyes can also be used in conjunction with lift eyes for a more robust lifting assembly — a versatile feature appreciated by boatyards and serious DIY installers alike.

Sea-Dog Line designs hardware for harsh marine environments, and many builders and DIY installers look for components that align with ABYC standards for safety-oriented installations. Whether you're re-rigging a trailerable runabout or outfitting an aluminum fishing boat, Sea-Dog's bow and stern eye selection provides the material choices and engineering detail to do the job right.
