James Turner I was in CRD21 (Coastal River
Division 21) and served aboard PTF19 during her last
year at NTC Naval Training Center) Great lakes, Ill
(Waukeegan, III) and during the transit to NAB
(Naval Amphibious Base) Little Creek, Va to
CosRivRon 2 (Coastal River Squadron 2, our parent
command).
Does the transom still leak
excessively? SOP was to remove the boats from the
harbor each Sept/Oct using a synchrolift and trolley
to avoid ice damage and do hull maintenance. During
the last winter at CRD21 we fiber-glassed the
transom (rather inexpertly I'm afraid) to try and
stop the steady leakage into the lazarette. Think
the join between the chine / keel and the transom
wasn't quite tight. Probably due to vibration and
age. Not sure the transom was Philipine Mahogany
like the hull, so there may have been rot in there.
We repaired some gunwale damage (on
the starboard side?) at the round where the forward
sweep of the gun'l merged with the almost straight
side portion of the gun'l. 17 boat managed to run
into us during a gunnery exercise. They had two or
three hull planks stove in while we had one section
of gun'l damaged. That was interesting since none of
us had been trained to do repairs on a wooden hull.
17 boats OINC didn't have a sense of
humor, and became somewhat annoyed when we painted a
large band aid around the damaged portion of their
hull.
Never did get quite comfortable with
the startup sequence on the Napier Deltic main
engines. Put the control station selector into RUN,
put the throttle into neutral, unpin the governor,
pull the boot off the turbocharger intake, spray
starter fluid (Ether) into the turbocharger intake
then rapidly put the boot back on and hold down the
air start valve.
I was used to smaller Greymarine and
larger Fairbanks Morse engines, so to me the Napier
Deltic's sounded like huge barrels full of aluminum
buckets rolling down hill until the engine started,
then once it settled down sounded like a large
sewing machine. I was never quite sure the governor
would catch the initial acceleration surge and that
it would run away. Never had one run away on me. Had
to shut a main down once because of a fractured
injector line spraying fuel, but outside of that and
their appetite for oil (2135TH?) they always ran
extremely well. I think 17 boat lost a main when it
threw a connecting rod through the crankcase
sidewall in NY Harbor. That must have been
interesting.
Always had temp control problems
since the main engine heat exchangers were designed
for tropical salt water operations. The relatively
cold fresh water in Lake Michigan would over cool
the mains unless we restricted raw water flow feed
rates. Tried various configurations of blanking
plates but eventually we ended up simply
periodically adjusting the inlet valve to restrict
water flow to keep the mains at minimum operating
temp.
Also had trouble with the inshore
speed limits. The main engines did not like running
below (if I remember correctly) 2,100rpm. They would
run rough and overheat even when using better grade
JP5 rather than regular DFM fuel, so when we had to
operate around civilian harbor areas we'd usually
have to shutdown one main rather than almost idle
then periodically surge both mains.
Have a vague memory that PTF19, for
some reason, didn't seem to like getting up on step
as quickly as either 17 or 18 boats (CRD21 had
PTF17, 18, & 19), but then would try to stay up on
step longer than the other two boats. No idea why.
I don't remember many of the boats
handling characteristics. Most of my underway time
was below decks or up on the guns. That and I don't
know what CRS2 did to her after we handed her over
to them. 19 boats OINC was Lt Curtis J Froyen during
my time aboard. He was the best of the CRD21 OINC's,
even if he was a devout Notre Dame fan, and he would
remember more. No idea where he is now.
Figures the picture with the best
contrast would be the one with that horrible camo
job the staff at NTC stuck us with. If I remember
correctly, CRD21's CO (Commodore Johnson) lost a
bet, and we ended up trying to camouflage the boats.
There was no camo pattern known to man that worked
on Lake Michigan. We called that particular pattern
the amoeba paint job. Ick.
Will see if I can find any of my old
pictures. No guarantee's since I haven't seen them
for a couple of decades.
