Looking at different UL boards

[photofr]

Looking for a new board… but quite specific & hoping someone will be able to help with links.

Does anyone know of a board that meets the following criteria:
14' to 18' in length
Truly rounded edges AND bottom (closer to a surfski than anything else)
24" to 27" in width
Recessed deck to the max
Stiff & light overall weight

Ideal usage: calm water racing

** you have no idea how much this would help, especially if you have links **
