Works Like Wood, Lasts a Lifetime!

King Starboard is the original and leading marine grade boat plastic polymer sheet building material. Since its introduction, it has been the choice boat building material for marine parts previously made from teak wood. Nothing on the water maintains it's original color and structural integrity longer.

King Starboard simply cannot rot or delaminate, and it is virtually maintenance free. It's unique polymer formula is environmentally stabilized to deliver a previously unattainable level of consistency and resistance to the elements. It is easy to clean and never needs refinishing. King Starboard plastic lumber is available in a variety of colors and sheet thicknesses and can be easily cut and machined using standard wood working tools.

King Starboard is used exclusively by Teak Isle Mfg., the leading OEM supplier for component plastic marine products. Experienced boat builders and boaters know the King Starboard brand and trust it above all others.

King Starboard has three limitations to consider-
  1. It cannot be glued
  2. It cannot be painted
  3. It has less structural rigidity than wood
While there is some debate regarding gluing Starboard, we have never found an adhesive that we've tested and trust to structurally adhere Starboard. We would advise caution and skepticism if anyone tells you differently and we always recommend using mechanical fasteners with Starboard.

Paint (including polyurethanes) simply will not adhere to Starboard and upon drying will easily peel away.

Structural Rigidity
While Starboard is incredibly durable (and nearly impossible to actually break), it does not have the same structural rigidity as wood. For example - If you lean a piece of Starboard against the wall in your hot garage, you will return the next day and it very likely would have started to flex a bit.

The degree of this "flex" will vary by material thickness, but depending on your application, parts fabricated from King Starboard may require some metal stiffeners. If you have questions about your intended use, we'd encourage you to give us a call at 866-633-7961 to discuss if stiffeners would be required.

Easy to use, beautiful results!
I was so glad I came across this product! I needed to re-gauge my boat dash as my old multi gauges were no longer working. I looked into having a machine shop CNC machine a piece of aluminum but quickly found out how expensive that would have been. Instead I purchased a sheet of this King Starboard and cut it out myself using a drill, jigsaw, drum sander and router. I was even able to cut and shape some parts with an exacting blade. It turned out awesome!! I would highly recommend this product to anyone!
Wired up and ready to go!

Trim around a window in a shower enclosure
Several years ago I was determined to find a product that didn't have to be painted constantly in a shower enclosure. The window in the shower always seems to be compromised because of the trim. I did not want to loose the window concept in the shower so I had the original double hung window replaced with a new vinyl one and had the starboard routed and cut to be the casing, trim, sill and apron. It looks outstanding and 4 years have passed with zero painting scraping or agonizing over leaks. Very pleased with product!

I have a 1987 175 trophy fishing boat and am looking for a replacement floor, would this material be suitable?
jamie l on Mar 26, 2018
BEST ANSWER: Great Question Jamie,

This material could be used for flooring but due to the fact that it is plastic, it has a tendency to flex. We highly recommend supporting it every 18 to 20". If it is being used in an outdoor setting you may want to use our anti-skid starboard that would be better suited for a deck. I have included a link below. .

I'm considering using 1/4" board as the under belly of 12' x 8' trailer. The framing would be screwed to steel channels at 16" o.c. 7 I'd divide it into (3) 4'x 8' sheets. Is 1/4" material strong enough? Do you know it's modulus of elasticity & it's weight per 12"x12"x1"?

BEST ANSWER: I do not believe that 1/4 or 1/2 inch would be able to handle a load on 16 inch centers. 3/4 may, depending on what the load is, but to be safe, it would take the 1 inch.

I have used the 3/4 in my boat and had to brace it every 6 inches in order for me to be able to stand on it ( I go about 250 lbs) with out any flex. At 10 inches it might have held me but I was not willing to take the chance.

While it will last forever, unless there are other considerations, I would go with something less expensive like plywood.
I want to make a salon door, with this product work?

BEST ANSWER: Yes this stuff is easy to work with. It has a textured finish. I made a new helm for my Boston Whaler.
