Asked how Calkins came to work for Peterson, having
earlier been his mentor, Andrews told me: “Yes, there was a
bit of the mentor working for the progeny who made good.
Doug was also a lifelong friend of Skip’s son, Chris Calkins,
so the relationship was more than just work.” And regarding
Calkins’s in uence on Peterson: “I thought Doug drew from
and expanded on some of Skip’s cruising boats with the
Peterson 44 [13.4m] and Kelly/Peterson 46 [14m]. In some
ways, the hulls looked similar to the Calkins 50 [15.2m] but
with the stern truncated by a transom instead of drawn out
to the full canoe stern. Doug had a great feel for the exit of
the boat with an emphasis on reducing drag by putting the
water back together properly.”
Besides Calkins and Andrews, Peterson also had Jim
Pugh (Reichel/Pugh Yacht Design; John Reichel also
apprenticed with Peterson) and Peter Wormwood (Stiletto
catamarans, etc.) working together—an all-star team for
certain. No wonder so many races were won.

Yacht designer
Doug Peterson
of San Diego,
California, died at
age 71. He came to
fame in the 1970s
during the IOR era,
and also worked
on two successful
America’s Cup
campaigns, one for
the U.S. and another
for New Zealand.

A di erent approach to preventing pink stain is to seal
the vinyl surface; Streptoverticillium reticulum w o n’t g r ow
“where there is nothing to eat.” Such a coating is PVDF
(polyvinylidene  uoride, or the trademarked Kynar). APV
makes two suitable products, Vynguard Weldable PVDF
and Vynguard with Kynar PVDF, that will not allow plasti-
cizers to pass through them. Combine ZPT with a water-
based slurry and apply to the top, back, and inside of seat
cushions. Streptoverticillium reticulum, you see, can get to
top surfaces through the back door by being absorbed on
the underside of the substrate.
So there you have it: pink stain on white vinyl is caused
by bacteria.
