The 38s5 is larger and faster of course. It was designed due to the
success of the 35s5 which was selling very well in Europe. Jack Horner
warns that the shoal draft model has a keel that draws less than the
rudder. I haven't sailed the 38s5, but would expect it to be a lot like
our boat, fast and responsive. Horner also mentions the boat's numbers
adding up to an initially tender boat.
The interior is essentially identical to ours with a bit more floor
space. The charter version with double aft cabins has the head forward,
while the 35s5 charter version kept the head aft. Here's what Bob Perry
has to say about the Stark interior designs:

"The first Beneteau interiors that were designed by Starck were greeted
with comments about radically modern style. I find these interiors
novel and modern but strangely comfortable with their blend of aluminum
details and curved, dark mahogany panels. In some ways, these interiors
seem more traditional than do the "apple crate" all teak interiors that
bombarded us in the last decade. "

We preferred our odd ports to the mismatched ports of the 38s5 because
they let more light in. Other than that we agree with Perry's
assessment. These interiors are rather shocking when you first see
them, then end up feeling even more traditional and warm, especially
with the teak interior and dark fabrics. I guess that's partly why they
won design awards.
I think the 38s5 is a great boat...get aboard for a sail and let us
know what you think.
