A heavy-duty vessel for whatever the day holds. Nautically Inspired, Built to Last.

If you are looking for a heavy duty vessel that brings a touch of maritime history to your daily routine, Oceanus Brass has designed a unique piece of drinkware. Launching on Kickstarter, The Bowline Mug combines raw nautical utility with premium metals. By attaching a solid brass boat cleat to a machined stainless steel cup, it serves as a steadfast, tactile centerpiece for your morning coffee or evening pour.
PROJECT OVERVIEW
Name and Creator The Bowline Mug by Oceanus Brass.
What It Is The Bowline Mug is a nautically inspired, heavy duty drinking vessel. It is crafted from a solid block of 304 stainless steel and features a prominent solid brass ship horn cleat that functions as the handle.
KEY FEATURES
Solid Stainless Steel Body The main vessel is machined from 304 food grade stainless steel. Instead of insulating your drink, it adopts the temperature of the liquid inside to establish a raw, tactile connection with your beverage.
Solid Brass Cleat Handle The mug features a heavy duty horn cleat handle made from solid brass. It provides a resolute grip and is mounted entirely on the exterior, meaning it never comes into contact with your drink.
Custom Patina Development Because the cleat is made from uncoated brass, it will naturally oxidize over time. Your daily routine and the environment will create a rich, custom patina that makes your specific mug completely unique.
Multiple Size Options The project initially launched with a 6 ounce capacity meant to feel substantial without being oversized. Due to popular demand from backers, the creators have also introduced a larger 10 ounce version.
Heirloom Durability Designed to endure the harsh demands of a bygone era of sailing, the mug relies on the sheer strength of solid metal to ensure it lasts long enough to be passed down.
REWARDS
Kickstarter Pricing The campaign offers the Bowline Mug at deeply discounted early bird prices to reward their very first supporters.
Options Backers can choose between the original 6 ounce size or upgrade to the newly unlocked 10 ounce capacity.
Delivery The Kickstarter campaign is incredibly successful and runs until August 20, 2026. The creators will keep the community updated on manufacturing and fulfillment timelines as the campaign concludes.
CONCEPT
The core concept is Nautical Endurance. The team at Oceanus Brass believes that everyday tools should be built to last and carry a sense of history. By combining the heavy metal construction of 18th century British naval deck fittings with modern machining, they aim to create a piece of functional art that connects you to the sea whether you are on a boat or at your desk.
INSPIRATION
The project draws heavy inspiration from the old shipyards of East Boston and maritime lore. The handle design is based on a ship horn cleat, which is the ultimate anchor point on a vessel. The name itself honors the Bowline Knot, revered by seafarers for nearly 400 years as the King of Knots because of its legendary refusal to slip under pressure. Together, these elements form a cohesive tribute to naval engineering.
