Bobcat,
If only it was as simple as a ding in the new car door.
The hydrodynamics of the hull shape will be compromised with the indentation and will be a source of turbulence from that point rearwards. All things being equal it could mean the difference between winning and losing a race.
The top Tornado sailors at our club spend the winter fairing out even the smallest of blemishes and make sure that the hulls are completely fair.
It's probably not worth the hassle with insurance but you should get it fixed for piece of mind.
Do you have any pics of the fully rigged Blade for display ?
Regards,
Peter
