Hi folks,

I’m new here and wanted to ask you guys about your experiences and opinions about a problem all too familiar to me and friends with sailboats.
Basically it all revolves around winter storage (on the hard) and the ingress of rainwater turning the hull into a bathtub! This happened to a few friends of mine and others around the boatyard causing costly damage despite their efforts to negate the problem.
(Our boatyard and others around prohibits the use of covers unless they are professionally made to suit the vessel and in good condition, ensuring a proper fit... Very expensive)

As a result and after wrestling and obsessing about a REAL solution for many months I reckon I have came up with something that really benefits boat owners and eradicates nuisance water from the bilge over the winter months AND allows costly batteries to be removed from the boat altogether while on the hard, allowing them to be stored properly keeping them in tiptop shape for the impending season(s)

Generally it has – and still goes as follows:

The boat is lifted out the water and plonked down in the yard somewhere.

You winterize and prep the engine etc etc

The bilge pump and float switch are checked, the battery(s) are left in whatever state of charge they were in and will hopefully cope with any accumulation of water.

You walk away telling yourself it will all be fine, then find you are suitably distracted over the winter season but know that you should have been down to the yard to check – but again are suitably re-focused on other “important” things. Until eventually the sun starts to shine again and its time to get prepping for going back in

You arrive back to find a substantial level of rainwater in your beloved boat. Perhaps covering the engine or gearbox, perhaps even in the cabin – mechanical damage, fixtures and fittings, wooden furniture, upholstery, mould and mildew... on and on it goes – but how?

Simple – lots of things can and will go wrong:

Older boats leak or are more likely to leak – fact! Deck hardware, stanchions, glands(cable), standing rigging deck fittings... there are many places where small, almost negligible leaks can become appreciable over long periods of precipitation.

Ok, but I have a good pump and battery so why didn’t they save me?

Well – what condition was your battery in when you left it? Did you know a fully charged battery wont freeze until temps as low as -68.8 Celsius but one with 40% charge freezes at -8.8 Celsius ( http://www.trojanbattery.com/tech-support/faq/maintenance.aspx ).Not an uncommon winter temperature here in the west of Scotland! A completely dead battery has only water inside it and will freeze at 0 Celsius, the expansion of the ice will probably rupture the casing.

Bilge pumps – it’s a ruse! I work with pumps, large ones of all varieties on an industrial scale so I know about a few things that get skirted over when you buy one. 1000gph, 1500gph is the claim, well I’m afraid not my friends; give these pumps a height (or head) to pump and install some bendy ribbed discharge tubing ideal for snaking through to the abysmally located skin fit and watch your flow rate drop off a cliff!!! Leading to longer running periods. They also draw slightly more energy in cold conditions and draw in settled debris choking and restricting the inlet compounding the problem further – unless of course your bilge is beautifully clean!

Float switches – who’s never heard of a stuck float switch? It’s a well known problem that left unattended will completely drain and may destroy your battery.
Not to mention wiring problems caused by poor installation, blown fuses etc.

Here is a very real scenario – It’s the middle of winter, she’s an old girl now with a few leaks here and there but nothing major and that’s to be expected, the battery and pump have coped thus far with any water getting in but, the battery is a few seasons old now and although from a reputable manufacturer and of a suitable capacity in good condition some neglect has been allowed. Suddenly a sustained period of heavy rain ensues and the pump is called upon once more, the pump – a beefy fellow, very capable if the “juice” can be found to sustain it but, the battery is weaning... not quite managing to provide what the pump needs to defeat the head and friction of the pipe work ,the bilge water never quite manages to reach the pipe outlet – the float switch stays activated because the water level never retreats, the pump runs indefinitely until the battery is completely drained... but - maybe saveable? The weather then improves, blue skies – sunny, crisp with frost and minus temperatures. The now water in your expensive battery freezes... Game over!

Ever the cynic I hear you cry... but I’ve lived it and seen it repeated over and over.

Not everyone lives 5 minutes from the boat yard,
Not everyone has the time to carry out “due diligence” in the off-season,
Not everyone can afford to pay the boatyard to maintain their vessel over winter,
Not everyone has OCD and must check once a week or they will implode!

Still with me? Good. (I know I rant on a bit!)

What if a device came to fruition that could remove the risk of all of these problems and was not powered by batteries or electricity of any form, a device easily capable of keeping the boat dry, was simple and required no maintenance of any kind, a synch to install and remove, compact and powered by the very source of the problem – rain!
Is that something that may have some appeal?

I apologise for the mystique but I may have to patent this if there’s any interest – feel free to ask questions im interested to hear your thoughts.

I look forward to any replies.
 
A device already exists. It's called a 'cover'. When I remove my batteries, the soft furnishings, the instruments etc for warm dry storage at home over the winter, I put the cover over and everything is tickity-boo!
 
Never come across a boatyard that did not allow covers on stored boats so tillergirl has the answer - no patent required.
 
How do you manage to sail comfortably in a boat that leaks as badly as that? Sounds like a few weekends sorting out all these fittings that are letting water in would solve most of your problems. We made a cockpit cover for our boat many years ago. It is very effective at keeping most of the rain out of the cockpit, although any that does manage to pass it will exit through the drains. Otherwise I can predict with some confidence that when I return to my 28 year old boat at the end of April, having left it in August last year, the bilges and everything else below will be bone dry.
 
I'm more likely to fix the bloody leaks than invest in a rain-powered bilge pump. Already done so on two boats.

If a boat is such an old wreck that it fills up with rainwater and can't be stopped, perhaps the best answer is to drill a hole in the bottom and fit a drain plug, as used in dinghies :). You can get sturdy bronze ones for classic keelboats, which shouldn't be any more risky than a seacock while afloat.

Hate to have a boat that's leaks that badly! I always take my speed log out when it's on the hard so I can clean the bilges and leave it out til launching.
 
I've never heard of a boatyard insisting on tailor-made covers, where's this may I ask ?!

Also, if the boat really is beloved, one will visit her a lot more often, probably do maintainance and fit new stuff; no way ignore her for months then act all surprised if rain has got in.

Or as fitted as standard to Hallberg Rassy Yachts.
 
Fix the leaks ( a leaky boat is unpleasant to be aboard let alone left standing! )

Get a decent winter cover ( What yard demands 'professional covers? Some £10000 / year per foot place? Move yards :) )

Fit an sms monitored system to test the pump, float switch, battery voltage, charge state, mains and intrusion.

Fit a solar panel to keep the batteries charged.

Rely on a mechanical system to pump out water that shouldn't be there in the first place? No dice!

Stork_III,

is that so, HR's have a bung ?

Serious question.

Incidentally I'm a great fan of those brass dinghy bungs, fit them to all my tenders, taking the actual bung home with me; the red cap from a WD40 can makes just the right holder in the car so I can see at a glance if I've got it with me on the way to the club.

Anyway, Halberg Rasseys ?
 
If only we could market this with that new antifoul system that somebody wittered on about last year...

I am still looking forward to seeing the press launch.
 
Great feedback guys - cheers!

You all seem like a conscientious lot with regards to maintenance and I salute that - prevention IS better than cure!

Let me clear a few things up...

Firstly - A cover does jump out as an obvious solution. What our boat yard (In the West of Scotland) is nervous about is owners who cover their boats with pound shop tarpaulins lashed with granny knots and cable ties... in other words jury rigged efforts that when inevitably fail in the horrendous winds we can receive up here, add significant windage maybe damaging the boat and others around it and worst case scenario actually pull a boat over to start a domino rally! Put it this way, would you like to be the person with your beloved vessel parked next to someone who has something no too much smaller than a mainsail flapping about in a 70mph gale?
It could all become a nasty insurance nightmare for all involved. I can see their thinking, but it seems to be a regional thing....

Now to all who swear by covers, a question - Is it the case that you are so confident with your cover that you remove your batteries disabling the bilge pump all winter? Id be surprised to hear if thats a majority "yes"! Covers are a simple solution but they are not without their problems and wouldn't give me total peace of mind.
If its a cover and a bilge pump as a team then you run the risk of damaging or reducing the life of your precious battery as it has to remain aboard over winter.

"Pull the log out", or perhaps some other low thru hull fitting... Valid of course but many people get nervous about disturbing hull fittings, especially if they are sound.

I should say that what Ive came up with is a very simple and potentially cheap device (I'm not here to pedal my wares btw), way cheaper than sms monitoring systems and suitable solar panels.
I designed it to keep a friends open boat dry and its currently proving trials but I think it would be a great addition to perhaps folk who use a cover but want the further peace of mind that comes with having a device that will remove any water getting in without having to leave batteries aboard to power a conventional bilge pump.

So, Am I still deluding myself on a hopeless crusade because Im blinded by my bias? Or does some of what I said have some merit among you wise old sea dogs?? :o

I encourage the imminent onslaught!!! :D

Yes fitted into the side of the Bilge stub keel. Not sure when they started fitting but my previous HR31 (1994) had one as does my current HR34.Bilgeplug.jpg It means you can wash down the interior hull to remove all salt, dust etc and it all drains away, preferably when your on the hard.
