(I knew this would get started)

In the comparison tests I've read (Trailerboats magazine) the speed advantage
of Stainless was about 2 MPH. The cost premium was over 3X the cost of
aluminum. So... the choice is yours but from my perspective (and I've had
a boat for geez... over 40 years) I wasn't willing to pay the price
premium for Stanless given the minute performance advantage.
