Seachoice Single Shank Bow Eye for Tow Lines

Features include a 3-inch shank designed to secure tow lines or attach a trailer winch hook. The 1-inch eye diameter supports standard towing lines and bow mounting. Best for anglers or boaters who need a simple, robust bow eye with straightforward installation on bow or transom areas. A potential limitation is the added shank length, which may require pre-drilled holes aligned for specific boat shapes.
Extreme Max Stainless Bow Eye

This model uses a one-piece stainless steel construction with a 1-inch interior eye diameter and a 2-3/4 inch threaded shank. It’s ideal for boats subjected to frequent towing or line tension, offering durable corrosion resistance. Best for serious boaters who demand high-strength bow attachments and long service life. A caveat is the heavier metal and longer shank, which may require precise mounting clearance on smaller bows.
SeaSense 3/8″ Stainless Steel Bow/Stern Eye

With a versatile design described as a Bow/Stern eye, this 3/8-inch stainless option focuses on practical coastal or freshwater use. It’s positioned for general fishing and towing needs, offering corrosion resistance from stainless steel. Best for owners seeking a mid-range option that balances strength and utility. Limitation: it may carry lighter towing loads compared with larger shank options.
Seachoice Stainless Steel Bow Eye

Designed to secure tow lines or trailer winch hooks, this ½ inch bow eye features a face plate size of ¾ inch x 3 inches. Best for boats with smaller rigging or where a compact plate is needed. A potential limitation is it may support lighter loads compared to larger eye sizes, so verify line strength and load expectations before mounting.
ISURE MARINE Bow Eye, 1″ Eye

Made of 316 stainless steel with anti-rust and corrosion resistance, this bow eye is designed for tow lines and trailer winch hooks. A notable feature is the combined length and stud dimensions that support strong mounting in challenging marine environments. Best for saltwater use and heavy-duty tie-downs. Limitation: installation requires careful alignment of stud length and eye diameter to ensure proper line clearance.
heyous Stainless Steel Marine U Bolt Bow Eye

The package includes a stainless steel U bolt, two flanges, and four nuts, with a 1/2-inch diameter thread and about 3 inches of thread length. This design is commonly used as deck hardware in corrosive marine environments. Best for mounting flexibility and a secure hold with multiple fasteners. Caution: ensure compatibility with deck thickness and available clearance around the mounting area.
COC-LF 4 Inch U Bolt Set

This 4-inch stainless steel U bolt set features a welded base plate to reduce corrosion risk and provide a robust seal. Best for boats needing a welded, long, heavy-duty deck attachment. Limitation: larger size requires more mounting space and may not fit smaller craft or compact bow areas.
SeaSense Cadmium Plated Bow Eye

Cadmium-plated, Zamak construction, 3-inch bow eye in white offers a cost-effective option for light to moderate towing scenarios. Best for boats needing an affordable, standard bow eye with simple installation. Caution: cadmium plating may be less durable in harsh marine environments over the long term compared with full stainless options.
Buying Guide
What mounting style should you choose? Bow eyes come in single shank, twin shank, and varied threading. Consider shank length, thread depth, and eye diameter to ensure compatibility with your hardware and lines. Stainless steel offers superior corrosion resistance for saltwater use, while zinc or cadmium finishes may suffice for fresh water or budget applications.
How to decide based on load? For towing or winch-hook use, prioritize higher-strength materials and larger eye diameters. If you only need a simple tie-down point for light-duty activities, smaller diameter eyes with shorter threads may be adequate. Always verify the maximum expected load and ensure the mounting surface supports that load.
Installation considerations include drilling alignment, deck thickness, and clearance around the eye. Some products include a base plate or welded base to reduce corrosion and improve sealing. If your boat experiences high line tension or frequent towing, select models with robust shank lengths and reinforced mounts.
Material choice matters: stainless steel is preferred in marine environments due to corrosion resistance. U-bolt configurations provide versatile mounting, but ensure compatibility with deck geometry. For trailer setups, match the eye and shank dimensions to your winch or anchor system to avoid misalignment and wear over time.
FAQ
- What size bow eye should I choose? Choose based on the eye diameter that matches your tow line or hook, and the shank length that fits your mounting area. Common sizes range from 1/2 inch to 1 inch, with longer shanks for bow clearance.
- Is stainless steel necessary for marine use? For saltwater or high-humidity environments, stainless steel offers better corrosion resistance and longer life than plated options.
- Can I install a bow eye myself? Yes, with appropriate tools. Ensure correct hole alignment, secure mounting surfaces, and proper thread engagement for the shank or bolts.
- What is the difference between bow eye and stern eye? Bow eyes attach near the bow for towing and line attachment; stern/midship eyes serve similar functions at different stern locations or for stern tie-downs.
- Are U-bolt bow eye kits reliable? U-bolt sets provide flexible mounting and can be highly reliable when installed with proper clearance and tightness, but verify deck thickness and fit.
- Should I choose a plate or a threaded eye? Plates offer broader contact area and sealing, which can reduce corrosion risk. Threaded eyes are simpler to mount but may require more precise drilling.
