What spare parts do you have on board - which ones should I get?

[Krumelur]

I'm curious what you guys have on board in regards to spare parts?

* Impeller
* Raw sea water pump
* Oil filter
* Diesel pre-filters
* Fan belt
* Pulleys
* Shackles

Are there recommendations for stuff I should get that could potentially save a vacation?

[Yngmar]

About 2 tons of tools, parts and supplies! 

But then we're not on vacation

Let's see what would be useful for saving a vacation:

Underwater epoxy putty (Plumbing supplier)
Electric tools, including a box of crimp terminals and proper pliers (not the two-dimensional ones, those are worse than twisting wires together). Multimeter of course. Oh, and a set of WAGO terminals.
IR Thermometer gun, so many uses (troubleshoot fridge, engine, body temperature, etc)
Tube of adhesive sealant + gun
Some butyl tape/blutack
Bits of rope of various diameters
Hose clamps
Small inverter
Battery drill
Saw
Epoxy, the type that comes in a double-chambered syringe, and some cups and stir-sticks, for fixing/glueing small stuff.
Epoxy, half a litre of resin and hardener and some glass mat for fixing larger stuff.
A spare freshwater pump to swap in.
A spare toilet pump to swap in.
Silicone grease
Sandpaper
Dinghy patch kit
Spark plug for outboard
Sewing kit

And lots more

Now that I see your list I notice that most of this stuff is also on my boat :-)

[blue-max]

To the list provided byy Yngmar I would add (learnt from experiece)

1. Complete sea water engine cooling pump
2. Spare autopilot (complete)
3 spare gear/throttle cables
4 engine and geabox oil
5. antifreeze

I have many others on board but I can't think I have every used them and probably never will. They just fill lockers and bilges!

[Krumelur]

--> spare gear/throttle cables

This ^ is an excellent idea! I have immediately contacted SVB and a VP dealer to find the right lengths/type.

Just burnt out a regulator on my alternator which then blew the solar panel controller. Going to add an alternator to the list. Good list so far guys.

Just did a quick check: original VP alternator for a D2 is €1.200 and the version from SVB is €230 😳
I seriously doubt VP is building their own alternators.

[Yngmar]

Spare alternator is a good idea. Last I checked for a friend's boat the D2-55 (I think, don't remember which engine) had Mitsubishi alternators, which cost around 200 EUR without the green paint.

Spare throttle/gearshift cable is a also good. We have ours in place, zip-tied to the ones in active use, so the ends can be swapped over if one breaks (won't save you from crashing into the dock when it happens though!).

Also, fuses! A spare or two for every type aboard.

[Krumelur]

Another part I just remembered having on board: a spare prop. Losing a prop is likely one of the most annoying things.

Add:
Starting motor and domestic water pum

And Not To forget a lot of masking tape and a bucket of antifouling to paint the more of draught 😎🤪

When I cleaned my heat exchanger I lost one of the 4 big "O" rings. Went the VP £64 for the set (they don't do them individually! Needed to get engine back together as launch date was soon.

Very helpful string everyone - thank you!!!

[MagicalArmchair]

Spare steering cables? I need to replace mine as they are the originals - going to keep the old ones stashed on board just in case...

[Jam]

Every type of tape known to man!! 😬 self amalgamating, electrical,duct, sail repair.........and the rest

[MagicalArmchair]

Ah, and many, many sorts of grease. Silicone grease for the windows and other rubber things, white lithium grease, winch grease for, err winches, dielectric grease for electrical connections, PTFE special grease for the steering cables... I'm sure I've missed some...  ... then there are the light oils and cleaners! Winch oil, Silicone spray, WD40, electrical contact cleaner, sailkote (which is as valuable as myrrh!), many, many slippery things...

Silicone grease covers most of these. It's a dielectric grease (in fact it is what dielectric grease is). And it's also what winch grease is these days (used to be calcium grease for some). If you buy Superlube, which is silicone grease with PTFE, you can use one grease for pretty much every job, although it costs a little more that way.

And a tube of blue volvo propshaft grease for the underwater jobs. And some copper grease for hot engine jobs.

I've got a tub of lithium grease, but don't really have much use for it.

And acetone, white spirit, WD40 for the tools, WD40 Fast Release Penetrant for getting old screws/bolts out, cleaning alcohol and a tube of white and black MS polymer sealant, plus a not totally shitty caulk gun.

Not exactly a spare part, but fuel biocide is important to have onboard.  And a decent socket set.  I also have a torque wrench which helps with undoing stubborn fixings.

[Petef]

Just looking at the stuff people recommend, it might be wiser to just buy another boat and tow it behind yours, it would free up lots of locker space!   

[IslandAlchemy]

Why not just tow a spare boat behind you.

I replaced my 30years old fluke multimeter, which was prone against seawater (don't ask me why i know this  ) to a multimeter with a dc clamp meter, which price had dropped reasonable the last years. Pretty handy for nearly every electric job, i don't want to miss it.

We carry a lot of the above but also an assortment of stainless nuts, bolts, washers, self tappers and split pins.
Also:
Cable ties
Selection of rubber washers and grommets
Spare bulbs for the nav lights
Jump leads
Spare batteries for torches, etc.
