Evening shadows crept on cats' paws across the
bay and touched the two boats anchored off the outer dock. There was no wind.
Faint strains of country music drifted over the water from the nearby pub and
blended with night sounds coming from the forest on the backside of the
boatyard. The disappearing sun sucked the remaining life out of the crab pots and old sheds
that had hospitalized so many boats over the years.
It was a Friday and there was a small campfire in
the dirt in front of the machine shop. The yard gang was gathered around
swapping yarns as they were inclined to do when the weather was good. Everyone
was seated on something—a five-gallon can, broken wheelbarrow, keel block, lawn
chair, or whatever. Mudge, the main mechanic and a senior citizen of the bunch,
was setting the pace for this particular session. Yan, in his T-shirt
regardless of the temperature, egged him on. Mudge was easy to excite. And once
started, he was hard to turn off. Diesel engines were his long suit, and he had
jousted with the wooden-hull guys for as long as anyone could remember.
"Diesels are the heart of cruising" was his complete philosophy of
life.
There were lots of yarns to swap, and they tended
to grow embellishments over time. More than once a year the subject of oval
shafts would pop up, and this evening was one of those times.
Early in the season not so long ago, Lady
Garbanzo stopped for fuel. She was a large plastic boat complete with a
half-dozen aerials, two domes, endless windows, three-foot air horns, two
barking dachshunds, twin spotlights, and a huge dinghy complete with dual
outboards. The skipper prudently circled twice before finally edging toward the
fueling station on the main dock. The sea was calm. After some bow thrusting
and many forwards/reverses on each engine, Lady was finally sideways
along the dock.
Fortunately Mudge was shuffling by at the time
and he took a line from Lady passed
to him by a diminutive woman wearing curlers under a kerchief. Even before the
engines were shut down, a voice boomed over the boat's hailer: "Fill 'er
up." The skipper was staring down from inside the enclosed fly-bridge.
Mudge muttered, "peasant," to himself and acted as if he hadn't
heard. He finished tying off the aft line and ambled away toward his original
destination. In the meantime Yan and one of the yard's high school girls
arrived to do fueling duties.
The little woman disappeared inside, yapping dogs
in tow, as the captain descended from on high down to the dock. He was a small
wiry man with a crew cut and gold chains around his neck; he jangled as he
moved. "Fill her up, sweety," he said to the high-schooler who was
standing midships, "Dieeesel, if you please."
Yan came back from tying off the forward line.
"Can I help you?" he inquired of the skipper.
"Just wanted to fill 'er up. Here's my
Visa." He flashed a quick, flat grin.
Yan accepted the card and gave his assistant a
hand with the diesel nozzle. She was new on the job. Between them they got the
fuel cap off and fueling started. In the meantime the boat’s skipper uncoiled
the boatyard's fresh water hose along the dock and poked the nozzle into a deck
spout located forward along the rail of Lady Garbanzo. Within two
minutes the diesel pump on the dock shut off automatically signaling that the Lady's
tank was full.
"Got another tank?" Yan asked up the
dock, expectantly.
"No, that's it. The other one's full."
Yan clenched his teeth and proceeded with the
Visa card ritual. The total fuel bill came to $8.75. In the meantime the fresh
water filling operation continued. And continued. After an extended wait for a
phone approval from Visa, Yan took the payment slip to the skipper who was just
topping off his water tank. "Here you go," said Yan, trading the Visa
card and slip for the water hose.
As Yan coiled the hose, Lady's leader
scribbled his name and asked, "Say, you guys got any tricks for getting
more speed out of this boat?" He handed the white copy to Yan.
Yan paused in his coiling routine, his mind
quick-stepping through several scenarios. "You ever see steam rising
behind your boat as you go along?" he finally dead-panned, looking down at
his coils.
"Yea. Now that you mention it, I do. What
does it mean?"
Yan ignored the question. "Do you ever have
any vibration when you are running the engines over 2,000 RPM?" he shouted
innocently over his shoulder as he was returning the coiled hose to its place
under the hand-lettered sign: CONSERVE
WATER. SHORT SUPPLY.
"Yea, it seems like I do sometimes when I'm
driving from inside." Worry flickered at the corners of the skipper’s
mouth.
"Let's ask Mudge about it," Yan
returned. He'd noticed Mudge coming back their way looking semi-official in his
diesel-dirty coveralls.
"Say, Mudge," he said, "this
fellow's seeing some steam aft and feeling some vibrations. Wants to know if it
could be hurtin' his speed."
Mudge coasted to a stop and shoved his oily hands
into his stained pockets. He looked up at the sky for inspiration. "Well,
let me ask ya," and he tilted his big head down to the skipper, now
dwarfed by the pair. "Does yur boat sit around in a marina, unused?"
"Well…" there was a pause. "Yea,
most of the time," he admitted. "But I'm planning to give her a lot
of time this year from now on," he continued a little defensively.
"Hmmmm." Mudge screwed up his bearded
face. "Sounds to me like ya could have a case of oval shafts," he
observed dryly. "And they can slow ya right down. When a boat’s too long
sitting, its steel engine shafts get out round, they sag like an old
face." Neither Mudge nor Yan looked at each other.
"Oval shafts? Never heard of such a thing!
Impossible anyway," but there was a trace of doubt in his tone. The
skipper was pressurizing now. "And besides, I had the boat hauled and
looked at two weeks ago."
Mudge shrugged his shoulders and turned to go.
Yan, a smile cracking his face, was pivoting the other way to exit the scene.
"Wait!" exclaimed the skipper.
"What would sitting around have to do with the shafts?" He was torn
between departing in a huff and facing the music.
Mudge unturned himself. "When shafts sit too
long in one position, the weight settles in the middle and the shafts get outta
round," he said slowly so the words could penetrate. "They teardrop.
Get oval. Gravity, ya know.
"Once that happens, ya start getting an
oscillyation, an up and down motion as the shaft turns. This causes two
problems. Seen it many times. One," and he raised a blackened thumb,
"the prop wobbles a bit in the water and heats up. Friction, ya know. This
causes steam, the kind you see behind your boat. And two," an equally
black index finger took a position perpendicular to the thumb (Mudge was
European), "the oscillyation sometimes makes yur stuffing box jitter-and
that gives ya the vibration you mentioned. End result, ya lose horsepower and
eat up more fuel at the same time."
"Too bad," he trailed off, and once
more he turned to go. Meanwhile, Yan had eased to a position about six feet
away where he stood with his back to the pair looking across the bay, blue-gray
eyes twinkling.
Lady's skipper looked anxious.
"What does it take to fix?" he asked hurriedly, glancing at his pride
and joy.
Once again Mudge unturned himself.
"Well" and he scratched the side of his face through the salt &
pepper grizzle, "Ya got two choices. One takes time; the other, money."
"Go on," ordered the skipper, jangling
a little as he shifted from foot to foot.
"Ya can rotate the shafts so they are
opposite the way ya had them when the boat was sitting so long. Leave 'em there
for the same length of time and they will sag back to round." He paused,
searching his soul. "The other thing ya can do is put in new shafts. And
if ya do," he went on hastily," be sure and get ones with at least a
ten-year, no sag guarantee. 'Decade Shafts,' we call 'em. That's all I ever
use."
The skipper returned to his boat and with Yan's
help walked it along the dock by hand to free up the fuel pumps. Lady's
leader then disappeared aboard, hidden from view by the tinted windows. Two
hours later he emerged and found his way through the yard of faded dreams to
the machine shop to get more information about what Decade Shafts could do for Lady
Garbanzo.
