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.

Arctic White is Perfect for my 2019 Cobia 277CC
Boat Outfitters is always the first place I shop online for unique boating needs. The King Starboard in Arctic White is a perfect match to the top side Gel Coat on my 2019 Cobia 277CC. I use King Starboard on several projects, so I order sheets so that I can create things to organize my boat better.

Just what I asked for
Am replacing an ice maker with a fridge on a 41 Tiara Open. Had to have a trim ring to cover up the cutting required to widen the opening and the Arctic White Starboard was perfect. The color match is dead on, and the cutting, radius corners and rolled edge were exactly to spec. Highly recommend their starboard product and Boat Outfitters to do it right

King Starboard is King!
Fast shipping from Boat Outfitters! Material was easy to work with, using standard wood working tools as advertised. I made a faceplate out of King Starboard, for the new fridge I installed, in the cockpit of my 2018 Sea Ray 400 Sundancer. The Arctic White matched perfectly. The project turned out excellent!

Very nice product
I bought this product to mount a battery charger next to may battery in a Boston Whaler 130 Super Sport. I made a “t” shaped piece and used the seat screws to hold it to the underside of the bench next to the battery then mounted the charger on the side. This product is very easy to work with, I used my table saw to cut it and my router to shape it. I used stainless steal screws to put the pieces together it is nice and strong.

Good product, good service.
I used this material to make s plinth (base) to install a windlass on the foredeck of my sailboat. Starboard is easy to work, and boat outfitters sells pieces small enough to be economical.

I am replacing a removable floorboard on an 8' Achilles inflatable measuring about 31 x 38 inches. Would the 1/4 inch material be adequate and can I order it with rounded corners?
Burton C on Jan 9, 2019
BEST ANSWER: Hi Burton, Great question! Starboard is a very slippery material, it can be ordered in anti-skid. The only problem with that is that anti-skid only comes in 1/2" and 3/4". I would recommend that you cut your floorboard out of 1/2" antiskid Starboard and have the corners radiused.

Go ahead and give us a call at 866-633-7961 to get that process started or send us an email through our contact page online.
Hello, If made a template and mailed it to you, can you cut it ?
A shopper on Apr 25, 2018
BEST ANSWER: Great question! Yes, if you send in a template, we would be able to cut the material to your exact specifications. Please reach out to us to get started.
I plan on making a large swim platform for my boat the boat currently has a 12" swim platform molded into the boat. I want to use 3/4X 54 X 96 antiskid covering the original swim platform with this and extending out 3 feet. I plan on using 4 supports ( pipes) underneath to the transom. Think this is possible? this stuff strong enough? will it bow and and or sag??
Michael Y on Mar 30, 2019
BEST ANSWER: The material is strong, but the 3/4" will have to be extremely supported underneat for it not to bend. I had one made out of 3/4", but it was doubled up at certain areas as well as my swim platform had a stainless steel frame to support the whole perimeter of the platform, and it still bowe out in the areas that didnt have support underneat. I added another L bracket to that area and the problem was solved. with the four support pipes installed, if is not supported around the perimeter, it will bow.
any wider than 54 available?
A shopper on Dec 13, 2017
BEST ANSWER: Great question. The largest standard sheet size we carry is 54" x 96". If a larger sheet is required, we can reach out to the supplier. However, if available, the larger size would most likely have to be purchased in larger bulk quantities. I hope this helps.
What is the weight of a board that is appr. 72" x 110"?
Dawn J on May 17, 2018
BEST ANSWER: Hi Dawn to add to the previous answer, our largest sheet size is 54"W x 96"L, so we cannot cut a piece to 110"L. However, the square foot price of the 1/2" starboard is about 2.5 lbs/sq.ft., so this should help you determine the exact weight of any size piece you need. Thanks Dawn!
ALBERT F on Apr 30, 2019
BEST ANSWER: Yes it can. This product is very dense and can withstand a lot of abuse.
Star board? Would this material work for the backing plate used on Sea Ray seat cushions? This cushion is used to step down onto the floor from the sundeck so it needs to be able to support weight from its outside edges.
Greg R on Apr 27, 2019
BEST ANSWER: NO It does not have strength for that application, it will deflect
Can I make a custom sized in-console tackle box and drawers with Starboard? What thickness do you recommend and how is it joined? Glue? Screws? What do you suggest as a perimeter trim material to attach the unit to the console itself?
John B on Apr 14, 2019
BEST ANSWER: I haven’t found any glue that works on starboard. I have used stainless screws to fasten it and usually cut dados in everything to keep it sturdy.
What to use on joints for a galley counter top and back splash?
George on Oct 4, 2018
BEST ANSWER: Hi Roger, Starboard can be sealed (non-structural) using the Elastomeric Sealant that we have on the website. You could use this at your seams/joints. However, starboard can also be welded. I have included links for both options below. Thank you!

A 12’ aluminum boat? 1/2 inch thick. Approximately 36” wide x 4” long. Back piece approximately 14” long and 12 inches wide?
Brendan V on Jul 4, 2018
BEST ANSWER: Hello Brendan, typically we do not recommend Starboard as a structural replacement because it will flex. We do however offer Coosa board with is a direct replacement for plywood but it will not absorb water and it 30% lighter than plywood. I will include a link to that material for you to review below.

Can you bend the 1/4 inch sheet?
Gerard W on Jan 29, 2018
BEST ANSWER: Great question. Let me preface this by stating that we do not bend starboard. With that said, starboard can be heated and bent, but it will not hold the bent form. The material naturally wants to retract to its original flat form. If you are looking to bend the material, you will need to mechanically fasten it in place to hold the bend. Thank you Gerard!
I’m putting pads(seats) on aluminum toolbox s for my pontoon seats. My question is how thick would your product have to be for seat backing on a solid surface?
Mitch m on Dec 6, 2017
BEST ANSWER: Hello Mitch, if the material is being mounted to a solid surface you could really go with any thickness you would like but if it were me I would go with 1/2". That should give you enough room to countersink the mounting holes, but not stick up far enough that it would too uncomfortable for the back of your legs.
I need a piece 30" _ 76" _1/4". What would cost be. What kind of routed edge?
Mark balita on Aug 19, 2017
BEST ANSWER: Hi Mark, currently the price for a 76" x 30" panel of 1/4" Starboard is $110.83 when raw cut. If you would like the edges routed, it is an additional $10 for all four edges of one side of the panel, or $15 for all edges of both sides of the panel. With 1/4" thick starboard, we do not recommend routes any larger than 1/8" for both sides or 3/16" for one side.

Please also note that a piece of starboard of this size will incur over sized package fees for shipping through UPS. Also a panel this size has a larger risk of damage simply due to its size. There are two ways to get around this: 1. Order a panel size larger than what you need so that if it is damaged the damage can be removed by cutting it down to size, or 2. Contact us before placing the order and we can look into freight shipping. Freight tends to be a little more expensive, but it is safer in regards to damage. Thanks Mark!

Can you cut any shape if a DWG or EPS file is provided?
