King board/starboard/starlite
 

I am in the process of replacing 3 seats out of my SC21. I have been told of a number of options for replacing the plywood part of the seat. Some say use plywood again and coat it with a water treatment. Some say use marine plywood. And last but not least I have found the product I want to use- King starboard. This is a plastic which means it will not rot or get weak if it gets wet. I have managed to find it for reasonable prices and looks like it will run around 160$ for all three seats. The only problem I have is there is not a store nearby that has any product I can look over. I dont know if I should be getting the 1/2" or the 3/4" for seats that are 19x25. I see the 3/4 as being the safe route but at the same time it might be overkill and also end up costing 50$ more.
If you have worked with this stuff and know from experience what thickness I should use Im up for advice.

Here is a link to the product if you are not familiar with it.

I used it in my boat for the seats in the bow , the back , and the sundeck , and am using the starboard AS(antiskid) for the fuel sending access hatch. I am also in the process of making a console from it.
I think it's the best thing since sliced bread. No matter what you do to wood , sooner or later it goes to crap. Not King Starboard.
It is just as easy to work with as wood except it doesn't glue well. I bought a hot air welder to do my console so well see how that works.
I recommend it highly!

1/2" is plenty for that size of cushion.

Here is a pic of one of my side rails I did in starboard:http://i271.photobucket.com/albums/j...ss/boat073.jpg

Good to know. I'll be ordering the 1/2'' then. As for your photo, it did not load or it is not visible. Thanks for the reply!

Eh, worked this time! Looks good. Im going to order some 1/2" soon. Thanks for input

Re: King board/starboard/starlite
 

I got my seats back yesterday from the upholstery shop. They look great. The kingsboard was easy for the shop to work with too. He said it stapled just like wood. I know for a fact it cuts like wood. I had the pieces cut to my specs and then shipped. Well, 1 was too long and the other 2 were too wide. I ran to Lowe's and they cut them. The saw does not melt the plastic while cutting and the edges were sanded just as easy as wood. The 1/2" thick seats span 19"x25" and are only supported on the edges. The seats hardly flex and will be plenty durable in the SC21.

I ordered through "scrapplastic" on Ebay. It was the best price by far but like I said they did not cut exactly to my dimensions.

Re: King board/starboard/starlite
 

I've ordered from them too, great prices!

Re: King board/starboard/starlite
 

Larry, I'm thinking of replacing the wood on my sundeck w/ 3/4 inch starboard. What thickness did you use and did you have any issues? Thanks in advance.

Re: King board/starboard/starlite
 

Hey Chickman, what boat is this on? On the original Mariahs there is quite a bit of support for the sundeck meaning the entire weight is not just supported on the outside edges BUT in the middle as well. I would think the 3/4 in is good but Im sure the 1'' would not hurt! Another suggestion I would have- use the starlite board. It is just as strong as original kingsboard and weighs a lot less. Since the substrate is covered by upholstery the perforated edges of the starlight will not be visible. The 1/2'' stuff I used is much heavier than the 3/4'' wood it replaced- yet stronger.

If you can find a place that will beat the prices on this page let me know!

Cut to Size King Starboard Marine Grade Plastic Sheet


I ordered my stuff from scrapeplastic on ebay because the sizes I needed and shipping was free. Boat outfitters was my next stop.

Re: King board/starboard/starlite
 

And here is the link for the starlite stuff. It only goes up to 3/4''. Id call them to find out what they recommend.
If I were to redo my sundeck I would be using this stuff...

Re: King board/starboard/starlite
 

The boat is a 1996 200 Shabah. I just took measurements and it is 73" wide by 32" deep. Here is what I'm thinking. I'm wanting to redo it in starboard or something similar. Instead of reupholstering it, I'm thinking about having a cushion made that is just slightly smaller (maybe 70 x 30) out of marine vinyl. My thought process is to have 3 straps incorporated, (right, center, left) to attach to stainless mounts that are secured to the starboard. That way if I ever need to flip it over due to wear etc... I can do so. Also, I would think that it would be cheaper to replace the second go around if I ever needed a new cushion. Thoughts?

Back to my original question, if it is supported at the back and both sides, with a 5 inch starboard runner going where the head rests mount, do you think the 3/4 inch starboard would be strong enough?
