Marine Straight Bow Chock (also commonly referred to as a straight chock or fairlead) is a specialized marine hardware component mounted on the deck of a boat to guide mooring, docking, or anchor lines smoothly from the water to a cleat.
Unlike angled or "Skene" chocks which are handed (designed specifically for either the port or starboard side), a straight chock features a symmetrical, perpendicular parallel opening. This design allows it to be used universally on the bow, stern, or amidships to accommodate straight-line pulling without rubbing against the boat's gelcoat or causing excessive line abrasion,
Key Features and Material Properties
Material: Almost exclusively manufactured from cast 316 marine-grade stainless steel or solid cast bronze to withstand harsh, corrosive saltwater environments.
Finish: High-quality options feature a mirror-polished surface with heavily rounded interior radiuses. This slick engineering reduces friction and prevents catastrophic rope chafing under heavy loads.
Sizing: They typically range from 4 inches to 8 inches in overall length. Choosing the right size determines the maximum line diameter they can safely feed (e.g., 4 to 6-inch chocks generally accept up to 3/4-inch lines, while 8-inch variants take 1-inch or thicker lines).
If you are looking to install or replace a chock, what is the length of your boat and the diameter of the dock lines you plan to use? We can help you determine the optimal chock size and fastener requirements for your setup.
