(UNCLASSIFIED Information from 1979)
At this time, the 65 ft. PB is the newest, most advanced small Patrol
Boat in the USN inventory. It was designed as a high speed weapons
platform for the Naval Inshore Warfare forces, capable of carrying a
variety of U.S. or foreign weapons in a number of alternate locations. A
modular payload concept is incorporated, allowing the craft to be adapted
to a variety of missions in deep rivers, harbors, coastal or open sea
environments. Missions envisioned include patrol, surveillance,
interdiction, fire support against ashore and afloat targets and insertion
/ extraction of NIW units. The main deck of the craft is reinforced in
vital areas so that future mission capabilities, dependent upon the
development and/or availability of the necessary systems hardware, may
include anti-submarine sonar or torpedoes, mine laying, mine detection and
mine sweeping.
The craft is powered by three high power, lightweight diesels providing
speeds significantly higher than any other USN patrol boat of this size.
Fuel and Accommodations will permit unsupported missions of up to five
days or 450 NM (2000 NM at reduced speeds). Multi-frequency
communications, high resolution surface search radar and reasonable
stability in moderately heavy seas will permit day/night, all weather
operations. The all aluminum craft was designed with a low silhouette, low
radar cross section and extremely low acoustic noise levels to preclude
ready detection.

[ Webmaster: information from this section obtained from "The
Ships and Aircraft of the American Fleet", by Normal Palmar]
Builders: Marinette Marine, Wisc. and Peterson Builders, Sturgeon Bay,
Wisc.
The PB Mk III was developed as a multi-mission inshore warfare craft for
U.S. and foreign naval service. The U.S. craft are operated by the
active SBUs.
Classification: These craft are also designated as Special Warfare
Craft, Medium (SWCM). The Naval Systems Command designates these
craft as PB Mk 3l however, they are listed as Mk III in the Fleet.
Design: The Mk III is a modified commercial craft used to support
offshore drilling platforms in the Gulf of Mexico. These craft are
of all-aluminum construction with their pilot house offset to starboard to
provide maximum deck space for weapons and equipment. The craft has
low radar cross-section and quiet engines for clandestine
operations. Mission duration is up to five days.
Guns: These craft generally are fitted with an automatic 40-mm gun
forward and up to four .50-cal machine guns on pintle mountings.
These are also hard points on the deck for fitting larger guns as well as
missiles. They can also be rigged to carry mines, torpedoes, or
minesweeping gear.
One unit was used to evaluate the 25-mm Bushmaster cannon.
Missiles: The PB III was used to evaluate the Norwegian-developed
Penguim SSM with four stowage/launcher containers being fitted on the
after portion of the deck.

I feel like the Grim Reaper bringing bad news. I was just up in Wilmington,
and found that the other of the Sea Spectres rejected by California Fish &
Game was broken up in June by California Diesel.. That was the 65PB737.
They had already broken up the 65PB755 in 2000. To my knowledge, General
Propulsion still has the 65PB736 in their yard in Palm Springs; I've never
been there and want to take a drive over there in the winter when its cooler
in the desert. -George.

This is old news, but something none-the-less.

02/13/01 from Patrick Flynn, [Patrick_Flynn@nyc.yr.com]
There are currently 3 boats for sale on Guam coming up in next months
DRMS offering. I have done all the leg work for shipping, and have found
it will cost $150k to dry ship it from Guam to CA. A little too much for
my blood, but here is everything I have gathered to date.
If someone is
interested I can help with some of the shipping contacts I have used to
generate my pricing with Matson as they are the only shipper to go
direct between Guam and the West coast of the US.
The information listed
below was supplied by DRMS on Guam.
The Patrol Boats were sold in September 2000. The weights listed in the
catalog for that sale were erroneous and a waiver was required to be
signed
by the buyer. The boats were awarded but the buyers did not sign the
waiver
so now the boats are being offered on sale again. The high bids we
received
for the boats on that sale were, $54,432.00, $31,115.21
and $40,001.11. Those were the bids on IFB 50-0720, items 15, 16 and
17.
Bid Opening for the patrol boats is March 20, 2001 and inspection begins
March 5, 2001. The method of sale is sealed bid and the catalog should
be
available on the web approximately three days before the first day of
inspection.
Length Overall 64'- 10 3/4"

Full Load Displacement 81,800 lbs.
Light Load Displacement 65,500 lbs.
Hoisting Weight - Full Load 83,000 lbs.
Total Fuel Capacity 1800 gal.
Total Water Capacity 100 gal.

What ever happened to those 3
MKIII's in Guam that were for sale. I heard they were sold, then I heard they were pulled off.
Sorry I took so long to respond. I've been home about a week, but haven't
been paying much attention to E-mail while getting caught up on everything
else.
The MkIII's went back for sale on IFB 50-1710, with a bid-opening date of
03/20/2001.
65PB775 and 65PB776 both went to Dong Yang Steel (Guam) Co., P.O.Box 26396
G.M.F., Barrigada, Guam, 96921. The first went for $51,000, the second for
$46,000.
65PB751 went to Harbor Equipment Services LLC, c/o Bruce C. Spencer, PO Box
820, Cherry Hill NJ 08002, for $35,000. Dong Yang had bid $22,300 for her.
These were from the Bid Abstract list, which only lists the bidders and
their bids; its not actually the confirmation of who received them, although
its rare that the highest bidder doesn't win.
Hope this helps. -George.
Do you have any updated information about the 65' PBmk3? Your web site has info up to '79. I
know that 3 of them had major retrofit in '91. I did the air/water/hydraulics on
them at Mare Island. I got transferred before they were finished. I was there
for most of the work, but missed the good parts at the end I was looking to see how their
equipping them
now. Henry Berger [bgrmystr@tds.net]
Look - two MKIIIs now owned by private parties - Visit
their pages.
01/08/03 HI,
Attached are some pictures of a PB 777 taken sometime in 81. The boat is rigged with Penguin Missiles. I was an FTM along with one other FT, we were in charge
of testing the Norwegian missile.
You guys have a nice website.
