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.

Starboard Plastic Sheets
I think I will be satisfied in the future, because I've noticed while working with it that it tends to bend, even the 3/4 in sheet. I may need to reinforce it so it will hold its shape over time.

Just what I needed
Built my own custom trolling motor mount with this material and stainless drawer slides. Very ingenious and perfect.

Marine usage.
Starboard is the perfect material to be used on any marine product. I have used Starboard many, many times, and I was always very happy with the finished product.

Perfect. Came as described.
I ordered several pieces that I will be using to assemble a custom gauge box/panel on my boat. Pieces came exactly cut and routed as ordered. Product was properly packaged and shipped right away.

Pricing is great. Since this is a small project, it would have cost me 4x the $$$ to purchase half or full sheets and cut myself.

Can the starboard be glued together and if so what type of adhesive would you use?
terry on Jul 25, 2017
BEST ANSWER: No, and please be very skeptical of anyone to tells you otherwise.

We fabricate more King Starboard (3 million+ lbs annually) than anyone in the world. We would love to find an adhesive that could structurally adhere King Starboard, but in our experience it does not exist.

You can weld Starboard and there is King Starboard welding rod available if for some reason mechanical fasteners were not an option.
can it be used to replace a broke hardtop ?
A shopper on Dec 26, 2017
BEST ANSWER: We have had this question come up a few times and it can be used as a replacement but it would depend on how well it is supported underneath and how you plan on attaching it. Your best bet would be to give us a call if you would like to discuss the specifics of your project and see what we can work out for you.
I need to replace a door that is not flat, can Starboard be heated and bent on a 3 or 4" radius?
Tom W on Feb 15, 2018
BEST ANSWER: That's a great question! Starboard can be bent with heat, but then it will want to spring back to it's original shape unless it's secured with hardware. Please give us a call at 866-633-7961 and we'd be happy to discuss other options with you.
am interested in building a small elevated casting deck (with storage underneath) on the aft portion of my Lund deep V. Would you recommend manufacturing a 'box platform' with storage underneath with this material? Approximate dimensions would be 54"L x 24"W x 10"D
K N on Feb 12, 2018
BEST ANSWER: Hi Kevin, great question. Starboard is a great option for your intended purpose. You would certainly want a box frame for this, as it will add the support around your edges that you will need for structural integrity. This will also give you a good closed in storage area like you are looking for. I would also suggest breaking it into compartments and using the dividing panels as additional support. For more details our ideas, please reach out at 866-633-7961. Thanks Kevin!
I am interested in building a reclining chaise lounge on my aft deck. Will this material be rigid enough to support someone in a leaning position and will it resist bending, warping and deforming over time?
John Z on Dec 23, 2017
BEST ANSWER: Hello John, Starboard is sometimes used in building outdoor furniture do due its weather resistance and easy maintenance so it can definitely be used for your project. As far as rigidity and how well it would support someones weight, that would really be more dependent on the design, thickness used, and construction style of the piece but Starboard could be a great option for you. Please feel free to give us a call if you would like to discuss your project and see what we can recommend for you.
How much would the 54"x48" sheet weigh?
A shopper on Nov 16, 2017
BEST ANSWER: Great question, the weights for a half sheet (54" x 48") for the available thicknesses are listed below:

1/4": 1.25lbs/sq.ft. = 22.5lbs
1/2": 2.5lbs/sq.ft. = 45lbs
3/4": 3.75lbs/sq.ft. = 67.5lbs
1": 5lbs/sq.ft. = 90lbs

Thank you!
can this material be fiberglass overlaid ?
dennis r on Nov 15, 2017
BEST ANSWER: Hello Dennis, that is a great question. Unfortunately nothing really bonds well to Starboard so you cannot use resins, glues or paints on the material. What type of project were you working on? I would be happy to see if we have something that would work a little better for you.
I want to make a dual post leaning post to replace my captain chairs in my boat. Can this be bent or curved for the part that you would lean against and where the cushion would be. And would you suggest fusing or using a fasteners to hold it all together?
David T on Nov 11, 2017
BEST ANSWER: That's a great question! King starboard can be bent with high heat, but if it's not fastened down it will want to spring back to it's original shape. We would suggest using fasteners instead of fusing. Thanks!
Can this be used for marine seat bottom cushions?
Lupe C on Nov 2, 2017
BEST ANSWER: Great question! Depending on the support available for the application, this would work well as a seat bottom. You will want to make sure that if the seat spans a larger area it is supported, as the material may flex over large areas unsupported.
Can this be used for seat cushion bottoms?
Lupe C on Nov 2, 2017
BEST ANSWER: This can certainly be used as an upholstery substrate (seat bottom and/or back rest). You do want to use a pneumatic staple gun to get the staples to penetrate far enough into the material.
About the rounded edge option. One side vs both sides. If I choose one side, all four edges on one side will be routed correct? On side vs both sides, you mean front and bock right?
Rodrigo on Jul 30, 2017
BEST ANSWER: Hello Rodrigo, that is correct, one side would be the top 4 edges and both sides would be the top and bottom of the sheet.
