Free shipping nationwide on every order — no dollar minimum. Sold in sets of 4, 6, 8 or 12 coasters.
XL cup holder coasters for large insulated tumblers, with your boat name molded in. The oversized version of our custom boat coasters — same flexible TPU rubber, same molded lettering, sized so a wide-base tumbler actually sits in it instead of perching on top.
Oversized cup holder coaster dimensions
-
95 mm (3.74") outer diameter — for oversized cup holders, not standard 2.75" ones
-
90 mm (3.5") opening — takes an 88 mm tumbler base with room to spare
-
17 mm (0.67") deep — holds condensation off your upholstery
-
Material: flexible TPU rubber, 95A shore hardness
Not sure which size you need?
Measure across the top of your cup holder before you order. This XL is 95 mm (3.74"), built for oversized holders and wide-base tumblers. If yours measures around 2.75 inches - the common size on most boats and vehicles - this one will not drop in and you want the standard 69 mm boat name cup holder coasters.
Worth thirty seconds with a tape measure: every set is made for one boat, so a size swap is not something we can take back.
What fits
Measured against the base of the cup, not the widest part of the body:
-
Large insulated tumblers (88 mm base) — fits
-
Slim 20 oz tumblers (70 mm base) — fits
-
Water bottles (60 mm base) — fits
-
Soda and beer cans (57 mm base) — fits
Check your cup holder first. Measure across the top. If it is around 2.75 inches you want the standard size — this one will not drop in.
Why TPU rubber
Thermoplastic polyurethane is a flexible rubber, the same family used for phone cases and marine seals. It squashes into the holder and springs back, and it will not go brittle after a season of UV and salt. Big tumblers are heavy — the molded grip ridges keep one steady in chop, and water drains between them rather than pooling under the cup.
-
Ribbed lift tab stands proud of the rim so you can pinch it out with wet hands
-
Lettering molded into a recessed panel — not printed, nothing to peel
-
Two-color lettering so the name genuinely reads
Personalize it
Boat name over hailing port, lettered the way a transom is. Or upload your own logo — one-time $50 setup, then reorders skip it entirely — just $2 more per coaster than a boat-name set, from $14.83 each on a 12-pack. Good for marinas, charter fleets and dealerships handing a set to every customer.
Not just for boats — cars, trucks, ATVs, UTVs and golf carts
The 2.75" size is the same standard used across most vehicles, so a set works well beyond the water:
-
Car and truck cup holder coasters — keeps grit, condensation and spilled coffee out of the console instead of soaking into it
-
ATV, UTV and side-by-side cup holder inserts — the grip ridges matter most here, where a drink gets thrown around on rough trails
-
Golf cart cup holder coasters — rinse the sand and grass clippings straight out with a hose
-
RV, camper and tow vehicle — put the same name in the truck that's on the boat behind it
Personalize them with a boat name, a family name, a hull number, a call sign or a company logo. They lift straight out by the tab for cleaning, which is the part you actually appreciate after a season of use.
Common questions
Will this fit my cup holder? It needs an oversized holder, roughly 3.75 inches across. Standard 2.75" holders want the smaller size.
Will the lettering wear off? No — it is molded into the part and sits below the rim, so the cup never touches it.
How long does it take? Made to order, typically 3–5 business days before shipping.
Will a normal can still sit in it? Yes. Cans, bottles and slim tumblers all sit in the XL - the grip ridges hold them steady. A 57 mm can does have room around it in a 90 mm opening, so if cans are all you drink, the standard size is the closer fit.
Can I put something other than a boat name on it? Yes - a hull number, a marina, coordinates, a family name, or your own logo. Whatever fits the panel.
Do they hold water? Yes - 17 mm deep, with drainage between the grip ridges, so condensation stays in the coaster instead of on your upholstery.
Are they dishwasher safe? Rinse them under a hose or wash by hand. TPU does not like sustained high heat.
