Most custom boat flags are the wrong size, and everyone on the water can tell.
Customized Boat Flags makes marine flags to order — yacht club burgees, owner and boat name flags, race and regatta sets, dressing lines, and the same designs in lightweight nylon or heavy woven polyester.

Marine flag sizing follows conventions that almost nobody selling custom flags mentions, and they are not decorative.
Roughly one inch of fly for every foot of a boat’s overall length for an ensign-sized flag; about half an inch per foot for a burgee. A thirty-foot boat wants a burgee around fifteen inches on the fly. Order too large and it is conspicuous rather than generous; too small and nobody can read it.
So the first thing we ask is the boat’s length — or, for a club, the spread of member boat lengths — because most clubs need two or three sizes rather than one, and that is a five-minute conversation that decides whether the whole fleet looks right.
Why we exist
Flags get quoted as a rectangle of printed cloth, from suppliers who never ask what the flag is going on.
So a club orders one size for a fleet that ranges from twenty to fifty feet. A beautiful name flag arrives that cannot be read from another boat. And the hem at the fly is two rows of stitching, so it frays through in a fortnight of real wind.
A flag dies at the fly end
The hoist edge is held; the fly edge is free, and it flogs thousands of times an hour every hour the flag is up.
Four rows of stitching at the fly and a reinforced corner patch is the difference between a season and a fortnight. It costs almost nothing at the making stage and it is the first thing a cheap flag leaves out, because you cannot see it in a photograph.
Nylon or polyester is a wind decision
Lightweight nylon flies in almost no air, which is exactly what you want in a marina, an estuary or a light coastal breeze. It also wears faster in sustained wind.
Heavy woven polyester needs real air to fly properly and lasts several times longer offshore or on a race set that is out every weekend. Neither is the better cloth; we ask where the boat actually is.
Read from two sides, at distance, moving
A flag is read from another boat, usually against a bright sky, usually moving. That is a harder legibility problem than any printed sign.
We redraw for it — heavier letterforms, fewer words, real contrast instead of tone-on-tone — and we print so the design reads correctly from both sides rather than leaving one mirrored.
What we will not print
National flags and ensigns. Those are standardised and governed by usage conventions, and a made-to-order version of one is worse than none at all.
We make club burgees, owner and name flags, race and regatta sets and dressing lines — and if you need the other kind we will tell you where to buy it properly.
How we price
No dollar figures on this site. Price moves with size, cloth, finish, hoist and quantity, and it falls steeply at club and fleet volumes. Send the details and a real quote comes back the same day, with a lowest-price guarantee if you are already holding a cheaper one.
What we will talk you out of
One burgee size for a fleet that ranges twenty to fifty feet. A tone-on-tone design that will vanish against the sky. Nylon on an exposed offshore mooring. And a race flag whose whole idea is a detail nobody will see from the start line.
Every one of those costs us money to say and saves you more.
