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
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.

Loved the plastic
I cut out a piece of the plastic to replace a step that had been damaged. It is performing perfectly.
New step....before non skid tape applied.

Custom Starboard
I recently ordered 3 custom pieces of starboard for trim pieces on my boat. Turnaround time was fantastic and pieces look great in person. They match the old pieces to perfection only now they are pristine white. Thank you!

Starboard cut was perfect.
I needed to create a new backseat rest for a SeaFox 216 WA as there are none available. This worked perfect and cut was on target! Rod Holders came in and it was packaged and ready to go!

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.

Thanks.
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.

https://www.boatoutfitters.com/material/plastic-sheet/coosa-board

Please let us know if you have any other questions or if there is anything else we can do for you.
Will 1/2" Starboard allow any light through (translucence)? I need to replace a bow hatch and the original white polycarb does allow quite a bit of light into the cuddy.
Chris E on Aug 28, 2019
BEST ANSWER: I got the 1/4 thickness sheets and they do NOT pass light through...I imagi e the 1/2 inch won't either. I hope this helps!
Will white starboard yellow over time?
Richard D on Aug 25, 2019
BEST ANSWER: We have found that if we store the white sheets covered and then in cardboard boxes it does not yellow. However if exposed to manufacturing facilities atmosphere it does yellow over time.
Hi. I have a stainless steel bracket in my shower and need a solid white material that I can use to adhere to bracket top to serve as a seat. The size is 16” x 20”. Would this material work? Is it smooth and will it look nice?
gale f on Aug 24, 2019
BEST ANSWER: Yes, if the starboard sheet is strong and stable enough. Either 3/4” or 1” thick. I would use the 1” thick if there is room.
It can be cut like wood and use a 1/3” to 1/2” round over router bit on the front edge for comfort. Also counter sink the screw heads.
Would it work as a flexible 3"x18" placard to stick boat numbers on for float boat & can numbers be stuck to it and is it easily drilled & cut?
Ron B on Aug 8, 2019
BEST ANSWER: It is easily sawed and drilled but it is hard to get anything to adhere to it. One thing that does tend to adhere is a product called Sudbury which is also sold at boat outfitters
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 it.....it's very strong.
Hello, I am thinking of replacing the laminated panels around the outside of my back deck of my 38 Hatteras, will it hold up from the sun fading and outdoor elements ?
Stephan A on Sep 20, 2019
BEST ANSWER: Stephan, Starboard Plastic sheets are extremely durable when it comes to nature. I've use this product on my boats and have never had an issue. This product seemed to me to be completely sun and salt water safe.

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.
Does the white white turn yellow in sunlight?
Norm S on Oct 3, 2019
BEST ANSWER: No the color does not change do to exposure to sunlight
I have a horizontal bow hatch (was either acrylic or polycarb -1/2" thick x 24" x 24" non framed) that needs replacing. Is this material suitable for the application?
Chris E on Aug 27, 2019
BEST ANSWER: Yes, 1/2 " starboard should work well for this application. I used starboard to replace companionway boards and it worked very well.
I need to make a ski locker hatch that gets walked on a lot will 1/2” be ok for this without to much flex?. It is 16x40
Joe w on Aug 21, 2019
BEST ANSWER: As long as the hatch is supported around the entire perimeter it should be okay. I have found Starboard to be a fantastic product.
we would like to replace the steps inside the cabin. They are currently carpeted and look terrible. Is this material an option and do you fabricate them to match the existing shape if we provide a template?
Linda & H on Aug 4, 2019
BEST ANSWER: I think starboard would be a great subflooring structure but too slick to walk directly upon. Would need to be covered with floor covering of your choice.
I was thinking of using a piece of thick starboard for a storage mount for a 6hp outboard dingy motor bolted on the stern of my sailboat. Would I need 1” ?
Wyatt on Jul 16, 2019
BEST ANSWER: I believe 1" would do the trick. Suggest you give it good support on both sides (clamp to rail or attach to other vertical support) and keep it just long enough to fit the motor clamp.
Can you attach hinges to it with sheet metal screws and if so any special method for attachment?
frazld on Jun 27, 2019
BEST ANSWER: Hey Frazld, great question. Yes they will, working with Starboard is very similar to working with wood. If the product is going anywhere with the potential for corrosion we recommend using stainless steel screws. Thanks!
Can this be held in place by fiber glassing over it. I didn’t want to screw it into newly replaced boat decking. I’m worried about just screwing seat bases into just the decking as well?
Renée on Jun 26, 2019
BEST ANSWER: Hey Renee, great question. It is not recommended to fiberglass over starboard. However, Coosa Board would be a great alternative for what you're looking to do. The product number is 13770-42332. Coosa is designed to be fiber-glassed over and is fully composite. So, just like starboard it will never rot. Thanks!
can it be used to replace transom boards on 14' foot aluminum boat?
Daryl N on May 9, 2019
BEST ANSWER: I would not use it for a transom application. It can become pliable with heat and pressure applied. Your best bet would be to use marine plywood sealed on all sides with epoxy.
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
chemicals?
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
BEST ANSWER: Randy

Great question. We can absolutely cut Starboard to any custom size and shape. Please give us a call to discuss. We look forward to hearing from you.
Can vinyl lettering be applied to starboard...ie 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.

Thank you!
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.
