Samuel,
It would seem logical that there is no anti syphon then on the 301.
So then it does make it imperative then to turn the seacocks off, every time?
Cheers for your info.

Samuel, how did you manage to get the hose out in the end? I am in front of the same problem. These things in the 301 are enraging me! Currently I am struggeling with servicing the Harken 16 winches, which have been removed completely for maintenence... What did the designer smoked?
Best

It is a real fun game. The hose, having turned hard with age & being full of calcium no longer bends. So my solution was to pull on bits & cut into 225 mm lengths with a junior hacksaw & pull out piece by piece.
One problem is that Hanse builds these hoses in before fitting the outer heads panels & cleverly fixes them with cable ties . This means you have to put your arm up inside & snip the ties with a pair of wire cutters. however, to make things more interesting for us owners they also fasten in a few wires behind the hose so if you are not careful you cut those as well !! so be warned
When it comes to replacing the hose I sourced a hose clearly marked " sanitation hose" but without any wiring in it. It was also fairly soft & flexible. This has 3 advantages. First i was able to threadle it back into the space & get the required loop in it. Second , if I get a blockage I might be able to work  some of the likely blockage points by squeezing it with some grips. Thirdly I will be able to disconnect it in the event of a blockage & shower myself in efluent (Cry)whereas before the hose was too rigid to get off the header tank.

To be honest the best option is to wait until your boat is about 8-10 years old then go & see Inspiration Marine & get a new one & pass all the agro to someone else. Unfortunately i missed this point & am now too old to go down this route. When I did have the money & wanted to do it I felt that the new Hanse were so poor compared with the old ones I turned away. Now I spend my winters with my arm stuck up the panel behind the heads  or my head stuck up the stern tube etc etc

Have fun
Samuel

Samuel,

I understand you well, yesterday I really got enraged after facing the winch problem (for the starboard cockpit winch I really have to cut a hole in the aft cabin headliner to unscrew it, those winches never had been serviced before obviously for 18 years Dead). Before i left I just wanted quickly dismantle the hose to get the exact length for the new one and realized, that Hanse built it in in that clever way Angry...
But anyway, I still love moy boat and felt confirmed, that I have bought in the early begining an USB endoscope (http://www.pearl.de/a-PX1280-1390.shtml;jsessionid=e284489BC5C1F193A62EA3F9A278E18E2?vid=917&wa_id=40&wa_num=3&utm_source=googleps&utm_medium=cpc&gclid=COmvvM6G59ECFQoA0wodm8cE8g) to get a better view in Hanse's secret places...

Thanks for your kidn and quick answer,
enjoy you Sunday

Yes my 301 'Bloto East' Cowes  [ex 'Rioja'] fin keel had 5-8 litres of water under the inner moulding between rear of table and steps. As the boat moved it sloped forward appearing in the area under the inspection hatch in floor under middle of table, keeping the keel bolts wetted with sea water.
 In my  first case on my first sail the water had come from the exhaust syphon valve leak which overflowed the catch bottle and then filled the bilge in front of engine to overflowing,  then found its way heeling in a rough sea into the space between the hull and the innner moulding [the top of which you see when you lift floor between table and steps]. I drilled  an 8mm hole at the front of moulding above the deepest part of the well formed where the hull is shaped to fair the aft end of keel. Pump out with vacuum pump used for oil changes.
I did try sliding a 6mm tube in the gap between hull and inner moulding, but you cannot get the area dried out this way, a vertical hole in the front middle of moulding is the best way.

More recently a tap was left on in the heads, and the water filled the heads to overflowing over the door sill!!, it found its way under the inner molding and filled the same space. On pumping with vacuum pump through 8mm hole, I found this flood was pure fresh hot water [from calorifier] , proving beyond doubt that the hull is not leaking. So now all stays dry in the hull except when crew try and scuttle her by leaving taps on!

So take courage Hanse 301 team, take your electric drill, and drill a pump-out hole in the inner moulding but dont drill through the hull!

Deep Keel 301:
I drilled the floor some time back and sucked out a lot of water. Someone requested a photo of exactly where to drill. I finally got a couple of photos. I drilled about 12mm diameter, as shown and feeding my vacuum pump pipe straight down it seems to have got all water out. There is 70-100mm gap between the inter tray and the inner hull so little danger of puncturing hull!! And I will take no responsability if you do! and not realy necessary I cover hole with water proof duct tape.

I made it, Samuel!

First I have looked with an endoscope for the cable ties. At least not visible. I assume, the tube got locked in my case behind the cover. I have connected the new hose with duct tape as extension to the old one. Parallel I pushed the new hose through the hole behind the toilet and pulled under the sink (while twisting this end in order to push it upwards where tehre is some more space behind the cover). So it worked in the end.
(made me a bit proud afterwards Cool).

Helpful had been:
- I sprayed from both sides PTFE around the hose behind the cover
- removing the toilet pump to have more space to work.

There was not too much calcium inside, but the intention of the whole story was, to get rid of the permanent smell. So I have used a more expensive one: https://www.svb24.com/en/sanitation-hose-with-barrier-layer.html

Have a nice day!

Well now it's my turn to join the list of 301 owners who have found this void full of water. We had a failure of the heads outlet seacock which kept leaking whether open or closed. Boat has been out of the water to have all the (original non-DZR) seacocks replaced with DZR type. Anyway, the leak from the seacock got in between the hull and inner moulding and, just as for others, appeared in the bilge inspection area beneath the saloon table by flooding through the bilge pump limber holes between the bilge "proper" and the hidden compartment which, of course, it had filled to the brim.

Marine engineers drilled a hole following the pictures provided by perry and pumped out about six litres of water.


^Water pumped out


^ New "inspection hole"- for periodic pump-out.

Mark us down as another one with water in the cavity. Only about 4 litres of very mucky water.

Water in space under floor again:  Bloto has had another problem with water under floor;
We are currently in Brixham heading back to Cowes. We are in the last few miles of circumnavigating GB but thats a long story.
Back in April we were sailing up the North sea about to go outside the Farne Islands and the rocks around them; when we suddenly noticed water in coming into boat. We had no sailing wind and were motoring, thinking we had lost engine coolant I cut the engine and panic set in. As we were being drawn onto the Farne rocks by strong Spring tide. I quickly found that the water was not coolant but hot water from the calorifier. Restarting the engine we motored into safe water. We had had full tanks so we had to pump 100 litres out of the bilge. Having expected on this trip to do an engine oil change I had my trusty vacuum pump to suck the final litres from the under floor space. However despite my best effors it took some days of rough seas and vacuum pump to finally get all water out, and dry bilges.
Now,  the calorifier had been badly installed with only short hose tails on all 4 pipes [in and out hot and colds] and only single hose clips fitted at the very end of the hose tails.  The situation caused by the hose off would have been a lot worse had it been the engine coolant pipe fail, which would have put us into engine overheat and other dire consequences.
So Guys check your calorifier hoses and joints this simple non safety critical [the calorifier] item could lead to a real safety issue. Further the engine coolant hoses must be of a specification to withstand at least 97 deg C coolant temp. So check your installations.
