Be patient while cutting and drilling
I used this to fabricate stern rail seats for our sailboat. I was concerned about cutting, sanding, and drilling the marine board. I contacted the supplier and they were very helpful and provided useful tips. Cut out the seat with a band saw and sanded the edges. I was surprised at how easy it was to work with. You just have to go slow. Very pleased with the outcome and the support from the supplier. Great product!

Slightly warped.
Slightly warped. Dimensions were a little off. Looked like it was cut manually. But worked for what I needed it for.

This is not proper stiff Marine Board
Do not purchase this product if looking for stiff marine board material. The flex on this is more in line with 1/8” inch eisen glass. This product has zero backbone at all.

Great stuff
Great value and material was as described. Used it to build a cabinet for my boat. Easy to cut on table saw and work with in general.

NOT Marine Grade
I bought this to build some doors for my boat. Description says that it is Marine Grade, which should mean that it has UV chemical stabilizers in it. Nope. This stuff warps before your eyes. Be forewarned if you are planning on building some doors that this stuff is not reliable for outdoor use. You will end up having to do some tomfoolery just to get it to fit together correctly. As much as I hate to suggest buying the name-brand stuff, save yourself the aggravation and just buy actual Starboard.

Board was opaque, off-white, not white.
HDPE board I received was opaque, off-white even though the description and the bar code sticker on the item both say White. In the pictures I supplied you can see the difference between a white board and an opaque one. I am returning the item.
