Cobalt®: Neodesha, Kansas based Cobalt® boats, formerly known as Fiberglass Engineering Inc.®, is a proud manufacturer of high quality bow rider, cuddy and sport cruiser boats, who has won the J.D. Powers award for quality every year it has been offered. Unfortunately, Cobalt® made most of their Bimini Tops themselves in-house and no longer reproduces them. We offer top quality Stainless Steel frame, Sunbrella® stand-alone Bimini-Tops (no zippers for front, side or aft curtains) based on size: http://www.rnr-marine.com/purchase.php?product=Bimini-Top-Sunbrella-Stainless-Carver .

Factory Original-Equipment-Manufacturer (OEM) Canvas for Cobalt® boats: RnR-Marine™ was a leading dealer for the Original-Equipment-Manufacturer (OEM), who patterned and manufactured Factory Original-Equipment-Manufacturer (OEM) canvas for Cobalt® 206, 226, 227, 243, 246, 262, 263, 273, 292, 303, 323 and 360 boats from 2000 to 2014.

We produce new canvas (diagram explaining what each piece of canvas is called) in the Black, Captain Navy, Forest Green, Taupe, Alpine, Terra Cotta, Jockey Red and Plum Sunbrella fabric colors originally offered by Cobalt®, or any color you like. TAGS

Note: Since the factory OEM canvas and covers are no longer available, we can make EXACT COPIES of YOUR existing Tops and Covers, but cannot copy any canvas with windows (yet) due to window shrinkage issues: https://RnR-Marine.com/purchase.php?product=Copy-Canvas-Covers-ang#Options. The Zippers on Factory OEM Cobalt® canvas are size #8 (8mm high, 6 teeth/inch). We do NOT provide mounting hardware for Bimini or Camper Top Frames, as Cobalt® supplied these (and the instructions) themselves. Cobalt® installed the snaps in their boats, canvas and covers at their factory, so we cannot install the canvas snaps for you because we do not have locations (see Canvas/Snap Installation to learn about installing snaps). We can only sell factory OEM canvas and covers direct for Cobalt® boats over 2 years old. OEM canvas part number scheme: tag p/n [yyCBmmm mm tar-xxxxx-fcc] where [yy] is the year, [CB] is Cobalt, [mmm mm] is the model ([227 CC ] or [246 BR ] for example), [t] is the type of windshield (S=Std or W=optional stainless), [a] is (A)rch or (N)o Arch, [r] is the revision, [xxxxx] identifies which canvas piece, [f] is the fabric (A=Sunbrella acrylic, S=SeaMark) and [cc] is the color code. Cobalt® Hull Identification Number (HIN)HIN = COBsssssmbyy , where [yy] = model year. Windows are made with 30ga Eisenglass flat (not rolled) clear vinyl window material. Specifications, care and cleaning of Sunbrella , 30ga Eisenglass flat (not rolled) clear vinyl and other canvas materials are detailed below. In some cases (if the boat mfgr is out of business for example) you can upgrade the windows to Strataglass coated clear vinyl (approx. 50-60 percent more cost), however the standard Eisenglass (clear vinyl) will last for many years with proper care, cleaning and storage. We utilize our library of 1,000's of patterns to produce new, "made-to-order" Factory Original canvas for your Cobalt® boat. This is the same canvas originally offered from the Cobalt® Factory and sold by your local Cobalt® dealer (local dealers may only go back 5 years or so however, and charge local sales tax, which we do not charge except in SC and FL). No other canvas manufacturer has these patterns or the ability to produce the exact factory Original Equipment Manufacturer (OEM) replacement canvas and covers that were offered from the Cobalt® Factory when your boat was new.

Please be sure that you have the Factory Cobalt® frame or matching canvas.

comparison and measurement
There are no cancellations, refunds or returns on Factory OEM canvas, since it is all "made-to-order" for you. Some owners (and even dealers, when new) installed their own "after-market" Bimini Tops, T-Tops, Hard-Tops and Canvas, so please:

  1. Compare your canvas or frame to the Cobalt® factory OEM photos shown here,
  2. Check for tags with Cobalt® OEM part numbers on existing canvas,
  3. Verify that your existing canvas has # 8 gauge zippers (factory original-equipment Cobalt® OEM zipper size):
    • Zipper teeth sizes (or gauges) correspond to the width of the closed teeth in millimeters:
      • #8 gauge zippers have 8mm wide teeth and 6 teeth per inch and will NOT zip to #10 zippers,
      • #10 gauge zippers have 10mm wide teeth and 5 teeth per inch and will NOT zip to #8 zippers,
      • See zipper size comparison photo at right.
    • Please note that after-market canvas makers often use the large #10 gauge zippers.
    • Since it is very difficult to measure the zipper tooth width, the easiest way to measure zipper size is to count the number of teeth over 2 inches: a #8 zipper has 12 teeth over 2 inches and a #10 zipper has 10 teeth over 2 inches.

Additional Shade for Cobalt® boats : When its hot you can never have enough shade. Our Boat Shade Kits (starting at Error processing SSI file
) extend shade over the cockpit or bow (can even be used like a Spray-Dodger) and can be put up or taken down in minutes.

Factory Original-Equipment (OEM) Covers for Cobalt® boats : We offer Factory OEM Bow and Cockpit Covers (typically in durable Sunbrella®) to fit your Cobalt® boat perfectly.

Custom After-Market Covers for Cobalt® boats : We also offer after-market Carver® Custom-Fit™ Boat Covers (from $239), Styled-To-Fit™Boat Covers (from $229) and in Sunbrella® marine fabric (the best quality, breathable fabric for covers) as well as some excellent high-quality, but less expensive materials, that are designed as a precise fit using measurements taken from your particular model of outboard motor.
