Hi you'all,
Down in Mexico and need to repair a gash in the hull of my 2004 nacra F18. It's a 10'' horizontal gash, 4' back from the bow, in the middle of the hull. Lucky it's a clean gash and only through the outer skin and a bit into the foam. Would greatly appreciate some help with a few questions and any suggestions.

a. are these boats built with polyester or vinylester resin ?
b. anyone know what the laminate schedule is ? how many layers and what weight ?
c. would you grind and taper the existing laminates for the repair ?
d. what resin would you use ?
e. anyone know whoes gelcoat best matches the standard nacra white ?

thanks for the help
