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.

King Starboard Sheet
I replaced the teak trim under the center console of my 1978 Mako 21. The product cuts easily and a router makes for nice smooth edges. Normal woodworking tools can be used for cutting and drilling. I highly recommend this product for any marine application.

Custom King Starboard Pool Platform
I highly recommend Boat Outfitters to anyone looking to use King Starboard or Anti Skid Starboard. They cut the pieces I needed to fit on my pool platforms and shipped fast for both orders. The edges are rounded and smooth and it's easy to walk on. Thank you!
Boat Outfitters helped figure out what sizes of King StarBoard to make a pool platform and wall!

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.
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 Seadek material be affixed to Starboard?
A shopper on Mar 20, 2018
BEST ANSWER: Great Question,

Seadek can adhere to starboard but we have had limited success in the product staying on it.

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'm removing wood decks from an aluminum boat. What thickness of King Starboard would you recommend as a replacement?
A shopper on Nov 5, 2017
BEST ANSWER: Starboard is a great material for small deck pieces but we typically do not recommend using it for for full deck rebuilds. You may want to look into Coosa for a project like that. I will include a link to the Coosa board that we carry for you below to review.

Please let us know if you have any other questions or if there is anything else we can do for you.
I’m changing my anchor windlass will king starboard be a good base/adaptor plate for the top of the deck?
Revbmw on Feb 12, 2019
BEST ANSWER: Yes I think it will. I was amazed how strong the 3/4" starboard's very strong.
Can I use it for the bottom of my fish tank?
fishboy on Feb 1, 2019
BEST ANSWER: It is extremely flat and waterproof, so it would be good for a base to support an aquarium, but you will need to design the same as plywood for strength (support below). You will want to put a coat or two of paint or sealer on to seal off the fiberglass fibers to avoid any itch from contact. It is mostly smooth, but there are exposed fibers.
I need to make a custom shower bench for a handicapped person, I was considering using this 1/2 thick material for the top, they need to be able to slid across bench top and into the shower. Additionally, Does this material hold up well to soaps and cleaning
Kevin B on Apr 16, 2019
BEST ANSWER: Yes, Great material to work with.
I have an outdoor kitchen with shelving etc made of Starboard and LOVE it. It has been perfect for outdoor weather conditions. Now I am thinking of using it to make a raised vegetable garden. Is this a good idea?
Cassandra C on Mar 28, 2019
BEST ANSWER: Starboard would work this application. It is weatherproof, sturdy and easy to work. Not sure I would use if for a garden container though. Just one man's opinion, but gardens seem better with wood. Less expensive, more natural, biodegrades (which you don't want a kitchen shelf to do). So, personal preference should guide you.
My boat seat base broke. Would this material allow me to staple the cushion material to it?
Dave C on Mar 20, 2019
BEST ANSWER: Yes, This is a solid material that can be worked like wood.
I need to make a hatch cover for my O'Day Daysailer. Would the 1/4" material be flexible enough to conform to the curve of the muddy? Also, what mechanical fasteners do you recommend?
chris K on Feb 24, 2019
BEST ANSWER: We used these sheets for a fish table. I would say they are somewhat flexible.
I am interested in using this product to act as a "lid" for the two rear corner compartments on the back corners of my 19' skiff. The reason I want hard plastic is so someone can stand on them while casting as opposed to the cushions that are on top of the compartments currently. This is not meant to be a pretty upgrade or anything, just simply a modification to make my boat more fishable. Can someone stand on this material repeatedly without it bending or breaking?
Tyler on Feb 23, 2019
BEST ANSWER: yes the 3/4 thick panel will work for you. Use strong hinges and route the edges round. you may have to screw blocks on the bottom of cover to keep them located when they are stood on. Good luck
Can I build a Flat Bottom Fishing Boat with you product ?
Gerald L on Jan 13, 2019
BEST ANSWER: I would say yes,, but remember it must be drilled with pilo5 hole bd then screwed using stainless flat head screws,,,joints below water need to be sealed,,nothing will adhere to starboard but a bead of sealants will leave a film between joints and won’t leak,,remember thro bottom paint or any paint won’t stick to it, and remember the weight of product when considering the thickness,, for boat bottom,,I think it’s more impact resistant then fiberglass,,increable product,,
Will you custom make a piece from King Starboard?
Randy M on Jan 11, 2019

Can vinyl lettering be applied to will it adhere to it. I am considering using the material to make a company sign?
Ricardo D on Dec 20, 2018
BEST ANSWER: Hi Ricardo, Great question! Nothing will stick to starboard, and it is also quite heavy. If you use our expanded PVC, this will certainly hold vinyl lettering, paint, and printing of any kind. The expanded PVC comes in white and gray and can be cut with any woodworking tools.

If you have any other questions, please do not hesitate to reach out to us at 866-633-7961.

I have a 6hp motor mounted to a piece of wood 1 1/2 inch thick which is bolted to the transom of my Beneteau sailboat . The wood is rotting, was wondering if I could mount a piece of starboard ( 4 bolts) in place of the wood that has been here since it was new, 1988? Does it come in 1 1/2 inch thickness?
Bryan on Oct 31, 2018
BEST ANSWER: We would love to help you with this project. Please give us a call to discuss. We look forward to hearing from you.
Is the 1/2" strong enough for a bow filler cushion to sit on?
PAUL M on Jun 16, 2018
BEST ANSWER: Hi Paul, We would recommend using a stiffener to support any substantial amounts of weight, especially with 1/2 material.
I’m looking to make a platform for my kayak, will this support 120# and able to screw into if needed?
Inshoreyakkin on May 15, 2018
BEST ANSWER: Hello Alan, it definitely could but there are some things to consider regarding the thickness and dimensions, it would probably be best to give us a call to discuss your project by phone with one of our sales reps.

I want to use this for my portable table saw platform. Does it come in any other color? White is very hard on the eyes when working in the sun.
A shopper on Apr 20, 2018
BEST ANSWER: Absolutely! I will include a link to our product page that shows all of our color options for you to review.

Have a great day!
Can this be sanded into a concave shape?
A shopper on Apr 7, 2018
BEST ANSWER: Great Question,

This product can be sanded into a concave shape.

Can this product be painted? We would like to add sand to the paint to help with slip resistance.
Shannon R on Mar 20, 2018
BEST ANSWER: Great Question Shannon,

This product cannot be painted because the paint will not adhere to the starboard. If you are looking for an antiskid alternative we have anti-skid starboard on our site. I have included a link down below to help! .

Can you use this plastic to attach to wood for an indoor loft bed slide?
A shopper on Feb 28, 2018
BEST ANSWER: Great Question,

This product can be used for bed slides. But there are more economically smart ways to handle that issue

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.
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.

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!
