Connecticut State Boat Flag 12×18 Inch – Single Sided with Reverse 100% Bleed-Through Print on Back – 200D Nylon – Brass Grommets – Fade Proof Vivid Colors – Connecticut Nautical Flag for Boat or Car

Yes. The 200D nylon construction and brass grommets are specifically the correct specifications for salt water use. 200D nylon is non-absorbent — it sheds water rather than absorbing it, so salt spray does not saturate the fabric and accumulate salt crystals in the weave the way polyester does. Nylon is also UV-resistant and does not degrade under the combined direct-plus-reflected UV load of an on-the-water environment. The brass grommets are corrosion-proof in salt spray — brass does not oxidize in the salt air and salt water environment that Connecticut Sound boating creates. Steel or zinc grommets corrode within one Connecticut Sound season, leave rust stains on the flag fabric, and can seize against snap hooks making flag removal difficult. For Long Island Sound use, the rinse protocol after each day on salt water (described in the Care section) extends the flag’s service life. For vessels kept in Connecticut Sound marinas year-round rather than seasonal use, remove the flag during winter haul-out periods and store it dry. The flag is not designed for continuous year-round exposure in a Connecticut Sound marine environment without periodic care.

The standard powerboat stern pole mount for a 12×18 boat flag uses a 12–18 inch fiberglass, aluminum, or carbon fiber flagpole inserted into the stern flagpole socket. The pole is typically 3/8 inch to 1/2 inch diameter and has one or two snap hooks at the top. For a two-snap-hook pole, attach the top brass grommet to the upper snap hook and the bottom brass grommet to the lower snap hook. Adjust the tension between the two snap hooks until the hoist edge of the flag hangs vertically — if the bottom snap hook is too low, the flag will hang at an angle; if it is too high, the flag will be compressed and will not fly cleanly. The flag should be oriented with Connecticut’s colonial blue field facing outward from the stern, with the grapevine shield centered and upright. On center console powerboats operating on Long Island Sound, the stern flag is visible to vessels overtaking from behind — which is how vessel operators approaching from astern identify your home state registration area. If your stern socket is a single-point ball or fixed mount rather than a pole with snap hooks, you can use a cord tied through the grommets to secure the flag to the mount point. Check the Connecticut DEEP boater registration requirements for any display regulations applicable to state flags on Connecticut-registered vessels.

Yes, and this is one of the primary use cases for the 12×18 boat flag format. The 200D nylon material and brass grommets make this flag the correct construction for car antenna and window mount display, which is aerodynamically demanding in a way that the printed polyester stick flag is not. At 55–65 mph highway speed on Connecticut’s I-95, I-84, or Route 1, a flag on a car antenna experiences sustained aerodynamic force that causes rapid grommet deformation on steel-grommet flags and rapid surface print degradation on polyester. The brass grommets on this flag do not deform under the aerodynamic load of normal highway driving. The 200D nylon is flexible enough to stream at low speed and strong enough to sustain the tensile load of highway speed without tearing at the grommet attachment. Most car antenna mounts for 12×18 flags use a clip or loop attachment through the top grommet for a single-point mount, allowing the flag to stream freely from the antenna. The 100% bleed-through construction means the flag displays Connecticut’s colonial blue on both faces as it rotates and flutters at speed — correct for an attachment that does not hold the flag in a fixed orientation. Remove the flag before driving at speeds above 65 mph on Connecticut highways to preserve the grommet attachment points.

For a Connecticut Sound boating season that runs approximately May through October — with the flag flown on the vessel during active use and removed during storage, winter haul-out, and severe weather — expected service life with proper care (salt rinse after each salt water use, mid-season and end-of-season wash, severe weather removal) is 2–4 Connecticut boating seasons. The primary end-of-life indicators are fly-edge fraying from the cumulative aerodynamic fatigue of Sound coastal afternoon winds, and gradual color softening from the season’s total UV exposure. The brass grommets and 200D nylon typically outlast the flag’s color and fly-edge structural life — meaning the flag will show color softening or fly-edge wear before the grommets or nylon body fail. For vessels kept in Long Island Sound marinas on a mooring or dock with the flag flying continuously rather than only during active use, service life is shorter — plan for 1–2 seasons with continuous display. Inland lake use (Candlewood, Bantam) without salt exposure typically produces service life at the longer end of the 2–4 season range.

Return within 30 days in original, unused condition for a full refund — prepaid return label provided. Defects in print quality, nylon construction, or grommet installation replaced free within 30 days — no return required on defective items. Normal wear from Connecticut boating season use — gradual color softening from season UV exposure, fly-edge stitching wear from coastal wind cycling, minor nylon surface texture change from salt exposure — is expected product aging from regular use and not a manufacturing defect. Damage from display during severe weather events is not covered under the defect replacement policy.
