Boat is designed to be a foiler or a class legal F-18. Trunks will accept a straight foil, rudders and remove wings and you will be class legal for F18 racing.
???? You Where do you read that on the Essentiel??? I think you confused comments on another project. The Essentiel hull is not F18 Class legal as it is epoxy / foam core built and will not accept straight boards.
Only way hull to be hull class legal is to be epoxy / wood core.
You need to read well articles before transcripting what you think you understood. An F18 Class legal hull with a convertible dagger case is a project we will do coming months with a known A-Class / F18 builder.
"In fact this project , the new Phantom 'Essentiel' is basically what we have in mind as plan B for the F18 Scorpion hull, and I even wrote a for the record document some months ago for the F18 Class WC, not on the foiling per se, but on the ability to fit a 4pt foiling boards setup on a convertible dagger case a la Nacra 15 and epoxy hulls (no carbon) construction to add structural support and longer life and the alternative to use the same platform in floating F18 legal racing mode and foil for fun."
