Breakdown and failure survey - please contribute

(1/15) > >>

Hi all. I am going to write an article for the BOA on breakdowns and failures, and how to fix them. I will publish it on this forum too. I would like some help compiling the statistics/information. To this end could I ask you take 5 mins to look at the information below and briefly tell what has failed or been a problem on your boat. The list below does not cover everything but covers most of the things we know about or are sometimes an issue or not.  Once I have done this I am hoping to produce some logic/process charts to help Bavaria owners fault diagnose problems and repair them, or point them in the right direction to maintain their boat to prevent things becoming an issue. I will cover rigging sails and possibly electronics an in another survey.  Could you just post the number and the letter(s) I will be able to take the data and run it through. EG (1) a b f g. (2) a f g, and so on. I do not believe that anything like this has been done before for any make of boat it could be really helpful to all Bavaria owners.
Many thanks. Ant

Sounds interesting. Thanks for doing this data gathering. Hope you'll get enough for a useful statistic. I'll start:

Bavaria 40 Ocean (2001)

1c) all stanchions leaked due to failed sealant (clear silicone)
1h) teak toe rail leaked due to shrinking/detached sealant (black caulking)
2e) MD22L-B raw water pump rear seals leaked and sprayed saltwater over engien and starter motor
4e) black gunk in diesel - filters thick with it but engine kept running
5a) blocked saildrive intake channels in leg (mussels growing inside from disuse)
8g) seals replaced
9i) fridge electronics dead, later refrigerant evacuated and recharged due to blockages
9q) contacts corroded
10e) corrosion - replaced

Hi Ant, sounds like a long project, good luck with it

Bavaria Vision 46 2014
1a port light above the galley area, fixed with new seal
2c thru hull fitting leaked in forward head inlet
2k raw water leak from Genset heat exchanger failure
10a cabin door lock handle holding spring failed so door does not stay shut in a seaway, fixed with new spring

Great data gathering project:

Bavaria 40 AC, 3cab (2001) my findings during my first two seasons

1 jk poorly installed new faucets by dealer
2 fk anchor box repair made by p.o. leaked around from anchor box exit holes
5 l - raw water filter seal allowed air to leak into system -> no raw water flow
9 hu - one battery "exploded" - plastic cover cracked due to internal fault / pressure + fresh water pump intermittently stuck if not used + inverter (sinergex pure sine) goes down to power-save mode even if set up not to do that
10 o - key broke inside lock (open position)


s/y Anniina

B 40 Cruiser 2009
1 b resealed but ongoing when hard pressed and these are underwater
1 h love tap from a Sydney 38!
3 a, just pushing my luck with old battery!
4 k, normal operation according to diesel mechanic. Apparently we sailors do not run our engines hard enough to burn off deposits!
9 q, just accepted that this is an ongoing fault. Had the same issue with a B 30 cruiser 2007
