Plascore core material

[W2F a V-King]

You could make 2 streams with the glass and resin from one of your old checkmates.....

Yes, that's my point... a stringer/cored, thin hull is as strong as a thicker hull made out of just glass. The Checkmate is not twice as heavy as a V-King. Not by a long shot. It's not as quick for other reasons besides weight.

The core in a V-King is a 32" strip down the middle. Not like the Vector that has a core running chine to chine. The Vector was not made for the weight/speed of the V-6 motors.

Would adding the glass down the middle be that much heavier than a properly bagged/infused blasa core 32" wide?

Area inside my sloppy black lines is the core in my V-King, maybe yours was different? From the sloppy arrow forward the core tapers to the bow.

Some guys have just added stringers and glass to the hull, deleted the floor and core. They have had no problems that I know of. A couple lays of 1708 would make it strong enough with a stringer every 12''. You might have some flex, but it would not be much...

remember that the floor was core as well in your vking. where is sits on the sides of the hull it doubled as core like the core on the very sides of a viper above the floor.

They did a good job with the box stringer/floor and core design I believe. I put mine back the factory way and it is very strong. The floor adds a tremendous amount of stiffness to the boat.

stole these pics of a comp vking off facebook and not sure if this is a factory comp but you get the idea on how different the stringer set up is on a comp compared to a standard with a floor

Thank You! Those pics help a lot!!

I have been told that in the pad they still run core even on a comp. I would think some kind of core in that area would be good. But you have to remember going with no core could cause issues when running in lake chop and hard hits on the hull. I am by no means an expert, remember that the most!

Yes, I read somewhere here that the pad on a comp has a 5/8 core, and 3/8 ( I think?) on either side.
I am no expert either, and thus all the questions and thoughts....

Being the fact that mine is not a comp, will building it like one make it as heavy as a stock V-King? Probably.

Comp has 4 more stringers (6 total) and a seat box made into the stringers on a lighter layup, no floor.

Doing all that on a stock production hull (minus the stock stringer box (2 stringers) and stock floor).

Betting the difference isn't much.

Man...all this thinkin has me wishing it was 5-Oclock..

Guess If one wants a comp, better to locate one and build it back the way they were made.

Samari on this site built his vking with 3/8 core I think. He blew it over and the core was all intact, the rest of the hull was not.

The white vking in the pics is merc mans on here. That boat is an 06 and built by a guy down south. He built 6 of them and his was the heaviest. Let me say, this boat hasnt been babied and yes it has stress cracks but for the most part its held up unbelievably well for a comp hull. Thiat sucker is strong and i know first hand how strong it is

[Deznuts3570]

No core in those 6 boats that i know of either

yess thats my boat and no core and composite transom as well no wood anyweres its strong as an ox i abuse it every weekend at the river no doubt

i The floor adds a tremendous amount of stiffness to the boat.

yes a well made and designed floor ties the hull from twisting side to side ,for and aft and racking , it needs to be raised as high as is practical and or have a camber built into it and the whole floor well secured to the hull .

I contacted the people at Corelite. Filled out a questionair on their website. I asked them about the corelite board, and their corelite pet products. Told them what I was working on, they responded very fast.

I will send off for a sample of the board and PET. I am curious.

Interesting note they sent back to me:

[quote] Dear James,

Thank you for contacting CoreLite. I will be happy to assist you.

The CoreLite Board in 2” should be stiff enough for a transom. CoreLite Board is commonly used in transoms without problems and comes already sanded and ready to be fiberglassed. We recommend that you perform your own testing as well, as the structural requirements may vary from application to application.

For stringers, CoreLite Board is an excellent alternative. However, if lighter material is desired, I recommend you consider CoreLite PET.

For hulls, CoreLite PET is an excellent solution as it provides great strength for its weight at a fraction of the cost of other foam cores. However, it is important to note that there is also no foam in the world that will be able to compete to the mechanical properties of balsa wood (I guess mother nature does it best). This explains why the majority of the world’s largest boat builders still use balsa wood core (and also racing boats, like Cigarette Racing boats). Balsa should never be a problem if it used correctly during the lamination process.


If you would like to go over more details with me over the phone, we can certainly schedule a phone call sometime next week. I am happy to help. Just let me know.
You can certainly purchase a sample sheet of any of our materials. Epoxy is compatible with all of our materials.


With kind regards,
