The reality of it is most boats don't have walk-in engine rooms (but we'd like them) or sea chests. Most of us have seacocks scattered throughout the boat with cramped ER space. That's the way it is. So we balance our risks with ability to service what we have.

This brings up an interesting part of the subject. What level of difficulty to access is acceptable? If they are too difficult to easily reach for normal use would they be accessible in an emergency?

People are more likely to be inconvenienced in an emergency than day to day.

This like so many threads ....I think the topic can be broken down into liveaboards, local to boat and distant to boat. Well....sorta....also throw in the ease of access and just plain human nature for exceptions.

But people who see their boats more are more likely to have a higher tolerance if their boat is in good shape.

I've investigated several sinkings and flooding events. In my area the causes rank as follows:

1. Dripless shaft seal failures. Typically plastic internal bushing seizes to shaft, spins seal housing and rips hose to shaft log. Or it is leaking badly due to wear, and pump fails or shore power fails.

2. Leaky std bronze packing, combined with pump failure or loss of shore power and flat batts.

3. Bilge pump discharges with through hull very close to water line, and no vented loop. Unusual trim or whatever combined with flat batts, water back flows through pump.

4. Heavy rain or hurricane combined with pump failure/flat batts.

5. Sinking "on the hill". Rain and no pumps, boat on blocks slowly floods.

Never seen a hose come off or burst while boat is on the dock. Have seen hoses fail on running engines, that's a different issue.

Closing sea cocks would have saved none of the above.

I agree. But rather than crawl-in engine rooms, I prefer sit-ins.

I leave all mine open, unless I am going outside in the ocean. Then, I close all but the engine thru hull. The ocean gets my respect. In the bay, I leave them open out of laziness mostly. Haven't had a problem in over 20 years.

I do not have a walk in engine room maybe on the next boat who knows but I do have a VERY roomy sit in engine room

or with both hatches up stand up except for ducking under the support beam

Our across the canal neighbor left his boat in Maine for the winter but the boat did mot have a garboard plug to pull.

Rain filled the cockpit which filled the hull deep enough to require a new engine.

Stuff happens , thinking ahead he might have pulled a low hose in the bilge and left the sea cock open. Of course hind sight is always 20/20 .

I couldn't stand the fact that my hoses were pretty much all 35 years old. I finally broke down and had them all replaced with top of the line hose and ss clamps. Peace of mind is priceless!

I'm trying to get the financial fortitude to have this done as well. I have no desire to DIY this and I just dropped $30K boat bucks in the last 6months. So I'm a little nervous running this one up the flag pole. Maybe I could use the "safety" story again?

Old hoses...keep seacocks closed a lot....


...or...


New hoses, clamps, bilge pump setups and feel good about even if something goes wrong...what's the worst case realistic scenario? Do you feel good about it...

------------------------

Funny you mention this, during my 4 day haul out this fall, I asked the yard to block my boat with the stern high so I would have ground clearance in case I wanted to pull the shafts. They were reluctant to do it unless I signed a notation on the work order and I had to assure them that my bilge pumps would be on. (Flush deck boat. . . even in the hardest rain no water would have entered the hull!!)

The marina in Ft Lauderdale years ago asked me if I had a garboard drain on my sailboat...I told them no.


A guy marched out and drilled a 1/2 inch or so hole in the bottom of my boat without even asking...they said..if stored on dry land...all boats had to have a way of draining the bilge.


Now I know better...but it doesn't surprise me if many more marinas demanded or drilled.

When we were in Panama I heard the same thing, not realizing that it was SOP for seasonal, long term cruisers (125 plus inches of rain annually).

One important item that was not mentioned yet (I think) was the value of a high water alarm. We have one installed in our bilge just above the level of the bilge pump sump. It is the loudest thing I have ever heard on our boat short of the Kahlenbergs, or the Admiral when she's upset about a couple of boat dollars. We live aboard and closing thru hulls would be most impractical--think refrigeration, A/C, genny etc. the high water alarm helps to give a peaceful night's sleep. Howard

Our boat has a very loud high water alarm. That plus nearby liveaboards plus a marina security dock patrol every couple of hous plus a who-to-call sheet in the window helps provide a sense of security.
