Sometimes the most difficult way is the best way. If your windlass power cables need extending, I would pull new cables by attaching the new cable to the current one with famous ducttape and pull back carefully the old cable, feeding the new one, and thus install a new one entirely to the connectors near the switchboard. In that way you avoid corrosion and bad connection in the high current power supply and do you make sure your boat does not start to become a DIY ship… but that’s my thought..

Ours runs under the side paneling along the inside of the starboard topsides.  Had to take the side shelf out in the process.

Hi all,
I also don’t see the need to put other treatments on a teak deck than water and soda or detergent.. teak in itself is non-skid and putting all kinds of oil on it is only cosmetic but does more harm than good to my opinion.
Don’t use HP washers or hard brushes to damage the surface, gentle brushing in small circles and if heavy green sweet scotch brite will keep your deck amazing. On our previous Bavaria 300, the new laid teak deck still was very good after 20 years in use…
It is the downside of teakdecks (besides the high price and sustainability issues nowadays) is they require a lot of TLC… so that’s why we also don’t have teak anymore on our Bav41…

Sing shanties while cleaning, really helps!

I need to extend the windlass power cabling.
It penetrates the forward bulkhead but the other side is paneled and not accessible.

Does it run in conduit?

How can I access the cables to extend?

Thanks.

I have been investigating using silcone oil as a teak deck reviver.
It brings back the colour
It stops water penetration
It is does not evaporate.
It can be controlled "dosed" by using dilution with volatile solvents.
It penetrates the surface.

The only drawback appears to be that that prevents any further application of other products - nothing will stick to it.

Does any one have experience or thoughts on this idea.

By corrugations you mean the U shape in some connectors . Aha that’s why they have it , I just read a paper from a researcher on introducing the U shape bent so it reduces expansion and stress.
Thanks a lot for your advices . I reconsider and come back .

if they are connected by a bus bar. I expect that fastening them together with an inflexible bar may cause fatigue and damage as the move even very slightly.  A well made cable and lug should be al you need without any of the disadvantages of a rigid bar.

I can envisage this as a potential problem as the battery terminals are only supported by the plastic casing as they pass through to connect with whatever magic happens inside these batteries..
Everything moves, flexes in a seaway, so a rigid busbar may be an unknown risk to your new very expensive battery bank...
 I've seen rigid copper bar used as heavy duty connections, but they all have 'corrugations' to allow for heat expansion and permit flexing..

Hmm I m not aware that I have to balance them regularly , I think BMS does that and I can do it very 6 months (the boat sails 6months per year) with the victron charger , or not?

In all the previous banks I ve installed I screw down to the floor the batteries with some distance between them . As I am planning to do now but with an extra frame around them . My guess is since they are fixed the bar is not gonna stress them , since there aren’t any forces applied to the bar except the cables elasticity coming from loads/charges. Is true that if the bar was the only element keeping them fixed it could be a problem. Maybe are you talking for some other stress force like vibration?

Putting aside the inability to balance the batteries independently if they are connected by a bus bar. I expect that fastening them together with an inflexible bar may cause fatigue and damage as the move even very slightly.  A well made cable and lug should be al you need without any of the disadvantages of a rigid bar.
