If the boom can't move it can't build up enough momentum to pull the grab rail out.
Maybe our 2001 34 was strongly built

You don't say what sort of holding tank you have. However, the plumbing should be obvious. If it is a gravity tank above the waterline it will have a 1 1/2" inlet at the top for the waste hose from the toilet, a 1 1/2 outlet at the bottom to go to the outlet seacock, a smaller diameter, probably 1" for the vent and an outlet on the top for the deck pump out.

This is the most common setup for a Bavaria, but some earlier (pre 2002 or so) had pumped systems with diverter valves so you could choose to either discharge direct overboard or send to the tank for later discharge using a pump.

Good information on the Tek Tanks website on the design of holding tanks and associated plumbing systems which might help you figure out how you should plumb yours.

Further to my earlier posts on this thread, herewith three photos, of which the first two show the hole cut into the aft bulkhead of the cabin in way of the area just to starboard of where the sliding hatch fits and at the top of bulkhead as viewed from the cockpit.

In the first photo the circular hole allows the rear of the ST60 instrument to be recessed into the bulkhead and shows the space that was available in the area just forward of where the hole was cut. Within the hole you can see the top of the longitudinal wooden bulkhead which, a little further forward, inside of the companionway door that forms the side of the companion way/aft starboard cabin bulkhead.

The second photo shows the area just to port of that companionway/cabin bulkhead but which lays outside of the companionway door, and which forms a vertical trunk/access down into the top of the engine compartment at its aft starboard corner. This trunk was used to route the cabling for the instrument.

The third photo shows the aft starboard corner of the engine compartment where the sound and temperature insulating materials used meet in that corner and where I have pulled a red wire so that it is just visible in that corner lower down. On my boat I have added some sound and heat insulating foam across the under side of the top of the engine compartment, such that the bottom end of the trunk referred to above is not actually visible. However with the use of some electricians glassfibre reach rods which were poked up from the engine compartment and past the insulation during initial investigations as to whether the proposed location for the instrument was viable or not. The investigation confirmed that the space reached the area next to where the instrument was to be placed, and the rest as they say, is history.

A similar space exists on the port side of the engine compartment.

Also the insulation added across the top of the engine compartment has substantially reduced the sound of the engine both within the cockpit as well as within the cabin areas.

Thanks for the information Bill, your holding tank interior is very clean which confirms that your system with hot water and HCL really does work.
I have a holding tank fitted, but not plumbed in yet, though it is on a long list of things to do over winter. Do you by any chance have a plumbing diagram that you could share for the tank connections?

I would also try replacing with a shackle and agree with Yngmar about tying off the boom.
We have a line with a small shackle that hooks onto the boom and a loop and a clip that goes round the grab rail. We then pull the taveller across and this stops the boom swinging.
We only take it off when using the main.

Be aware that the grab rail is not all that strongly attached to the cabin top, I used to do the same as you until one day arriving at the boat where I found the port side grab rail was (fortunately), still attached to the rope from the boom, but no longer attached to the cabin top. I plugged the holes that the screws had left with GRP filler and gel coat and re-attached the rail in a slightly different position such that the screws were secured into previously undamaged GRP. The slight difference in position is not noticeable unless you look very closely.
As for preventing the boom from swinging, I now use the midship mooring cleats to secure the rope ends, and have had no further problems.

Also Yngmar is right about the gooseneck lasting longer, I bought the boat when it was eight years old and the gooseneck for the boom was replaced within the first month of ownership. The new gooseneck is now nine years old and is in excellent condition, and the only differences that I am aware of is that I usually tie the boom off, and that the boat has been kept on a swinging mooring for the last seven years where there are no tidal or other currents in the harbour as such, and in consequence the boat always lays head to wind so the boom gets less of a battering from the weather.

Modifications & Equipment / Holding tank maintainance
« Last post by Odysseus on Yesterday at 12:37 »
Another maintenance write up to make things easier for people.

I put hot water in loo and pump it untill hose is full to get the pipe hot. Then HCL , ( hydrochloric acid as per my engine elbo write up) down loo and pump enough through to stay in just the pipe, and leave for 3 hours.

This breaks down crud in pipe,

Then close seacock outlet and pump hot water and HCL through into holding  tank, leave for as long as you can manage. This removes crud for the lower part of the tank where the crud collects.

Tools for this are.

Socket extension pieces with a turning joint on end, this is to insert into top of the sealing cap as it's the way to break the seal on the cap, give it a wack untill it turns.

When removed you need a mirror and light go see into tank and assess what conditions are like.

I have a 3 feet lenght of flexible  plastic that  bends enough to get through the cap entrance, my  (stick) can go through pipe and seacock when contence is released .

On re assembly  put grease around thread of cap, this will make job easiest  next time.

Vinegar does not work folks, it's an old wife's tale, your choice.

Hope this helps

If the width matches, a suitably sized U-bolt with the thread drilled out ought to do the job just fine.

That's some pretty dramatic wear by the way. May want to lash your boom down when the boat is not in use. Helps the gooseneck last longer too. We have a soft shackle connecting the traveller to the main sheet block, so there is almost no wear, and whatever there is is on the easily replaceable soft shackle instead.

Yngmar,

If you happen to have a picture of your soft shackle set up, I'd like to see it.  I'm concerned about the boom swinging on my 35E, as well.  I didn't have this situation on my last boat.  Thanks in advance.

This is most timely as we have just had a switch fail.

Thanks fit the info
