    Posted: 25 February 2019 at 09:07
Hi all,
I have been fitting a new anchor and longer chain to my 418, so emptied the anchor locker of rope and chain the first time, after 12 months use including regular anchoring on mud bottoms. I decided to wash the accumulated muck from the locker but the drain hole blocked very quickly.

Clearing the blockage was not easy, the drain hole in the locker starts at around 20mm diameter, but drops to 10mm lower down. Our mud includes a amount of shell, sized less than 20mm, more than 10mm. I can see blockages here becoming a regular event.

Are others experiencing this problem? Any ideas on how to manage would be appreciated. I am thinking about adding a restrictor at the bottom to the locker to at least keep the shell in the lock so it can be easily cleared. Not a great option, but possibly better than leaving open.

Any ideas would be appreciated.

Hi Gordon,
That sounds like either a design or build problem.  Have you talked with Windcraft about it?  I have flicked your note to them so they can address it with our 418 which starts Commissioning next week.

It sounds like the hole should be 20mm all the way through.  The only other way, short of a strainer of some sort, would be to reduce the entry to the smallest diameter.  Has it lost a collar of some sort which fitted into the hole in the locker which had an outer dimension of 20mm and an inner of 10mm?

Cheers

founds like you need to fit a mesh  or gauze over the hole if you have that kind of sea bed?

Bruce / Mark and Catherine,
Thanks for the replies.
I am talking to Windcraft (the dealer), but also wanted to see if the 418 is a departure from earlier models, of if there are other ideas out there.
I had thought about a restrictor, or mesh screen but don't want to do anything that further restricts the flow or stops fine mud washing through. I will think further, and see what I can come up with.

I think our 385 is the same, no screen and a fairly thin pipe that is smaller than the opening in the fitting.

Same problem here. I usually get all the chain within few months period clean all the mass. It is by design narrow.

Gordon,
 
Thanks for posting, I will check out the drainage on our 418!
 
Doubt a problem in sunny Australia but on a not dissimilar note discovered in the rather wetter UK that any lines stored in port rope storage bin can go mouldy. The starboard bin is fine as deeper so lines can stay dry but on the port side bin much smaller as has the gas locker and more open to the elements so any lines more open to the rain and staying wet. The 415/455/458 are all fully covered rope bins so not a problem. We are more careful now how we leave lines and have plastic mat now in port bin to raise to allow for extra drainage. 
 
Hope the weather kinder on Oz so an issue you will not see Smile
 
Best wishes.
Jon.

John,

No problem with mould in the rope locker in OZ. That sounds like more of a climate problem than design issue!

Yes this is an issue on our 345 too. 

I can only agree some kind of strainer is required at the inlet, and I can recommend blowing the tube back from below using the dinghy pump or water from a hose to clear the blockage.
