How about drilling no holes in the hull? The Tiger uses the same area that the bridle wire goes. It seems to be a very strong area as it is really designed to take a lot of load.
Line - Think about using Vectron instead of Amsteel. I think that Amsteel is Spectra. It is a really good choice after it is stretched but the Vectron will stretch way less. I use Vectron for that application and like it.
