Durable laminate for centerboard seals

[knoxville88]

I'm looking for a stiff, durable Mylar or laminate material to use for centerboard flaps , something that can handle a trunk opening just under 2 meters long. Ideally, i'd like to find it in bulk and from a US supplier. Any leads would be appreciated!

For tough, bendable stuff, give marine-grade Mylar or PET films a shot. US composite or marine suppliers usually have these in bulk.

Thanks for the tip!! Marine grade Mylar sounds promising for the flexibility and durability i need. Do you happen to know if these films hold up well against constant water exposure and UV? Also, any specific thickness you'd recommend for centerboard seals to balance toughness and bendability?

I had to source flap material for a similar project and ended up using 10mil Mylar drafting film, it's stiff, durable, and comes in rolls. I found it in bulk through McMaster-Carr, worked perfectly for centerboard flaps.
