760.0. "Tales of Damp Carpet" by SEARAY::EAST () Mon Oct 01 1990 19:37

    Ran into a surprising problem with my 25' Searay Sundancer this
    weekend.  Beware of running aground in such a beast...
    
    Somebody liberated my fishfinder (and all the rest of the electronics)
    a few weeks ago, so I had Lund Marine Electronics (Seattle) send me
    some new toys.  On FridayOur Hero jumps into the boat, and heads for
    the nearest sandbar, where I *carefully* nudged the transom onto the
    sand bar (power off, drive up, etc), and waited for low tide.
    
    Horatio Hornblower called this "careening", and I thought, if it's good
    enough for Horatio, it's good enough for me.
    
    So after the Attack of the Enraged Misquitoes (never have I seen so
    many!), night falls, I fall into a disturbed sleep, etc.  Periodically,
    I got up, dragged her a little more into the sandbar, and waited for
    morning,w hen I was sure the transom would be high 'n dry.
    
    Interesting, the number of people who stop by a boat, leaning at 22�
    degrees, bow down, transom dry.  They sure give you a wierd look when
    you tell 'em it was intentional...
    
    The part that surprised me about all this was when I leapt into the
    boat, jumped down the campanionway, and landed in 12" of water.  River
    water.  Lots of River water.  Slosh.
    
    Turns out that the forward bilge pump outlet was now under water (since
    the boat was leaning about 22 degrees onto the port side, bow-in-water,
    stern dry).  So water entered through the outlet, bypassing the pump,
    and filled the boat to the same level as the river.  Took it awhile, as
    there's a loop in the line to prevent this from happening (didn't work
    too well).  So I'd run the pump for five minutes, and get the water
    down to a managable level.  Turn it off...wait ten minutes, turn it on,
    wait five minutes, turn it off, wait ten minutes...
    
    Did this for several hours.  No real damage, just a *very* surprised
    skipper.  (If I get up the energy, maybe I'll mention this "problem" to
    Searay...while not everybody careens their vessel on purpose, I've seen
    lots of people do it by accident up in the San Juans. Once saw a
    Bayliner that was *at least* six feet out of the water.  Amazing sight.
    Never seen anybody blush from 100 yrds before.)
    
    Eventually, the tide came in, and off I went, with my new transducer
    installed, happy as a clam (slightly damp).
    
    To add insult to injury, when I got back to the slip, I was talking to
    the harbormaster.  He told me I should have seen him first...he has a
    trailer and a truck, and would have been happy to pull her out for a
    few hours!!
    
    Arrrggghh!

     I did the same job by sitting in the dinghy and working underwater.
    Couldn't get up the nerve to beach it *on purpose*.
    
    One of the winter jobs I intend to do is to seal the cuddy floor area
    from the bilge.   Isn't it supposed to drain into the bilge?   Well,
    yes, but between the relatively high location of the bilge pump and the
    fact that they eked out every inch of headroom in the cuddy by dropping
    the floor to below mean bilge water level, I regularly get wet carpet.
    I've heard that this is not an unreasonable thing to do - the risk
    being having to manually bail if water gets in from above.  But I'm
    too chicken to go out and have 8' waves break over the cockpit anyway.
760.2THEBUS::THACKERAYThu Oct 04 1990 15:2018
    I've had a couple of boats over the last four years (21' and 25'
    cruisers) and both of them had water drain into the galley from the
    bilge. It seems to be endemic and a damnmmmmnm nuisance.
    
    The only way I ever get water there is 1) rain getting through the
    hatch, but with the bimini up it should be pretty rare, and 2) draining
    in from the bilge.
    
    Last year, on my 21 footer, I blocked up the hole and had a dry floor
    for the rest of the season. I'm going to do the same with the 25
    footer, now.
    
    Anyone else had this problem?
    
    I thought of putting an automatic pump there, but it's too difficult
    and expensive for small return.......

760.3Buy a Grady White...LEVERS::SWEETFri Oct 05 1990 16:286
    The forward bilge in my grady is well below the level of the floor in
    the cuddy, in fact you get to it by openning a hatch in the floor.
    Sounds like a poor design to me...of course a Grady White is made
    to get wet or wouldn't be any fun :-)

    How many Consulting Engineers does it take to replace a transducer?

	Funny you should ask that......

	Lessee, first we'd have to have an architecture for the 
transducer itself  - -  presumably that would conflict with the 
vessel's own architecture, but we could get a waiver on the grounds 
that single instantiations are special cases.  Then an architecture 
for the service delivery process, but we can't deliver any service 
until we have our infrastructure and tools architecture in place,
so.....  a) a diagnostic architecture for fault isolation to the most
economic field replaceable unit  b) a repair, replace or substitute
architecture to figure out if its worth messing with, replacing with
the right part or just using whats at hand   c) a whole logistics
architecture to cause the generation 93 digit part numbers that can't
be cross referenced and are always superceeded by another part number
that is no longer available.  d) training/education architectures for 
....gee, I dunno  - -  so people can be trained to change transducers, 
or is it so they can understand the other architectures ?

	Cutting across all this would be security architectures to 
ensure that only tranducers authorized for replacement are replaced, 
by authorized replacers, on vessels authorizes for transducer 
replacement  ....we can't have any tranducer horses, worms or viruses 
getting introduced into the system, can we ?   Then there's the 
accounting architecture to ensure that charge backs are properly 
mangaged  - -  another way of saying that everyone in the system gets
a fair cut at the customer's wallet. 


	.......should I go on ?
