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
Gluing
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.

Painting
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.

blank piece of Starboard
Delivered quickly and well packaged. Boat Outfitters even paid the extra shipping to send it ahead of a custom piece they were making for me so I could get to work on my project that I needed the blank for. Great service, great company, great products.

What thickness do you recommend for replacing new helm panel for electronics?
A shopper on Feb 13, 2018
BEST ANSWER: This is dependent upon what is being mounted to the panel. We recommend 1/2" thick starboard for any time a GPS (or larger/ heavier display) is being mounted. If you are only mounting switches or gauges, you can typically use 1/4" thick material. Thank you!
Interested in using 1/4” starboard sheets to fabricate a hardtop in place of the old vinyl soft top on a 2004 Jupiter 31 center console. Will this be suitable?
A shopper on Feb 2, 2018
BEST ANSWER: Starboard can be used for a t-top surface, although we do not recommend it. The issue you run into is seaming the cut pieces of material, as well as accommodating the curve to the structure. The material can be welded to close the seam that would be created in doing this, but we do not do any welding here. You can find the plastic welders we offer in the link below:

Thank you!
Can your 1/2" stock be heated and bent to form shapes in the cockpit?
Rick B on Dec 10, 2017
BEST ANSWER: Great question - starboard can be bent with heat, but it will want to spring back to it's original shape. It entirely depends on what shape you are forming and how you plan to fasten it down. I hope this helps!
I need to install a floor in an 18ft jon boat. I was going to use plywood but came across this product. Any recommendations on thickness for a floor? I want to reduce weight but have strength. And is there a better option than this product? Thanks
A shopper on Dec 8, 2017
BEST ANSWER: Hello, if weight is a concern I would not recommend using Starboard for the flooring. We offer a material called Coosa which is a direct replacement for plywood but will not absorb water and is also 30% lighter than the equivalent thickness of wood. I will include a link to that material for you below.

If you have any questions about Coosa please feel free to give us a call and one of our sales associates would be happy to assist you.
I was thinking about using this material for a bench in a 1978 13' Whaler. How does handle warping?
Glenn C on Nov 17, 2017
BEST ANSWER: Hello Glenn, we actually build a Starboard interior kit for the 13 Whaler. If you would like to check it out I will include a link to that for you below. For the bench it would need some type of support in the middle to limit flexing. We typically recommend some type of support every 18-20 inches or so under Starboard products that will have a persons weight on them.

I hope this helps and please let us know if there is anything else we can do for you.
I would like to order this in black but I do not see an option to choose the color during the product selection or checkout
Michael Florant on Jul 26, 2017
BEST ANSWER: Hey Michael,

The color is actually selected first, then you select size or thickness on that product page.
