the Best Looking and MOST DURABLE – Marina DOCK Number sIGNS

At OutdoorNumbers.com we are direct suppliers to private marinas and to public marina owners and operators.

Our marina number signs and directional signs are often selected by professionals who design, build, own and manage marinas. and other waterfront facilities including cruise terminals, port buildings and piers. All orders are made custom for that project.


We use only the best marine-grade polymer sheet and CNC fabrication, to produce custom number signs with a finished and professional look.


All numbers include:

  • Carved digits for great visual appeal and no sharp, inside edges.
  • In-line borders.
  • Counter-sunk holes for installation with flat-head screws.
  • Eased outside edges for a finished, clean look.


Our standard Slip Numbers are 4-inches tall and 6-inches wide; suitable for 3 digits at 2” tall. Our number signs are 1/4-inch

thick and installed with screws. We recommend and supply only 316 grade stainless steel screws; for concrete it is 410 stainless steel screws. We also have 1/2" and 3/4" thick material for larger number signs and dock and property signs.


Custom Number sets are made to order using your specific number sequence, color choice and size.

  • For 20 years our marina numbers have been installed at marina locations across the USA.
  • Our dock and slip numbers are machined from solid, 100% waterproof H.D.P.E. sheet material which floats

                            and is a fully recyclable polymer material. The material is designed for outdoor and UV exposure.

  • These signs are virtually unbreakable with no chipping or peeling and are far more durable than vinyl on aluminum or any printed or painted number products.
  • Special brackets and piling straps are available for mounting larger dock and pier numbers.
  • Numbers for boat storage racks are also available.


Outdoor Numbers also manufacturers separate cut numbers and letters for wall and building sign applications. Numbers and letters come with drilled and tapped holes on the backsides for all-thread mounting studs. Installation is as simple as following the hole pattern we supply.
