A buddy of mine bought a 30ft Cat after our year long Afghanistan deployment. We have been working on her for a while and are at the point of getting close to dropping her in the water. The X-owner has taken the name of the ship to his new ship, as it is the name of his deceased wife. That said he has asked my buddy to change the name. That all said, what is the "rule of thumb/sail" on this tradition? I always thought that it was bad luck, but if this gentlemen is asking for that reason, how's that go??? Any advice is appreciated.
