which boat
what gear and equipment you currently carry
which engine
type of cruising envisaged, for weekend sailing you would not need to carry very much, but for longer cruising you will be organising a workshop etc.
We might also need to know you personal limitations, do you expect to rebuild an engine at sea or prefer get you home equipment, such as a spare outboard..
Sorry.
EDIT.
You will get lots of advice on here.
Conflicting, Confusing,Cantackerous, Complimentary, Constructive, Comforting and a Complete load of B%llocks.
But sift through the aformentioned and some advice will be of help.
Yer Man Dog Watch is weird, not only a Raggie (those are Guys on ere what sail about cos they are skint and use the wind for propulsion, maybe you are too) but not only that He has Catamaran! Few! those Guys are in another league again!
Then again if You ever want to put an illustration on these Fora He is The Man to ask.
I think We put up with Him for that reason!
So this is a Gentle Broadside Newbie.
Carefull, don,t put a foot wrong, else We'll have yer!

2 Impellers, belt, oil, oil & fuel filters, hoses, jubilee clips, fuses, bulbs, range of screws & bolts, sikaflex, various tapes incl self-amalgamating, rigging spares, WD40, marine grease, range of ropes, range of cable ties, electrical spares, for starters!
FOR ENGINE
Drive belts,
Oil and fuel filters,
raw-water pump impeller,
alternator.
FOR BOAT
Toilet spares kit (I have a complete spare pump, having met an unhappy Brit who'd been waiting 3 weeks in a Portuguese port for a washer for his Baby Blake)
Stick-on sailcloth for spinnaker and working sails.
Full set of bulbs for all interior and navigation lights.
PTFE dry lubricant for sail-slides etc.
Contact cleaner for electrics
Penetrating oil (WD40 is pretty mediocre, the best I had was bought in Spain, called 5in1).
I've also got a complete replacement set of working sails, apart from solent, working jib (which goes on roller reefer as storm canvas), genniker, 2 spinnakers (3/4oz and 1.5oz).
Torches, conventional and LED, including head-torches for working after dark.
Electrics spares (universal meter, connector tool and connectors, insulation tape, wire, switches etc).
Cyano-acrylic glue, 2-part epoxy, roving and CSM glass, polyester filled paste as well as gel-coat and 2 part isophthalic resin.
I've a lot of other bits, collected over 15 years of sailing, which are more of nostalgic than practical interest.
Every annual fit-out I discipline myself to throw away outdated items, but the boat is still 50mm over her marks.
Club hammer and soft wooden plugs in case a dreaded seacock fails (don't get me started)
Swarfega and at least 2 plastic bags full of old rags to help mop up both yourself and the boat. (you'll never have enough)
Never mind spares for the loo as you can always go in a bucket (at sea not the marina!) but do carry spares for the bilge pumps or carry a spare bilge pump (its easier than shifting buckets of water)
spare/emergency VHF antennae as well as handheld VHF
If you're new you'll learn by experience but please, please do carry out basic engine checks before you leave port and don't become another statistic for the RNLI - they are not the AA or Social Services of the sea as some newbies seem to think they are.
Enjoy your boating whatever form it takes and welcome to the weird world of folk who hang out on the briny ... /forums/images/graemlins/wink.gif
I reckon you could carry a whole spare boat & not have the actual bit you need. Most of us carry tons of useless spares (often stuff that has been replaced as dodgy already). If we were honest 95% of spares & tools on board are a waste of space!
If your boat is secondhand you will find loads of such stuff lying around which the previous owner couldn't be bothered to take out. Also, you will find a number of problems with your boat that will require constant fettling to keep them working - this will provide you with a good stock of useful tools & bits!
Best approach? Go round the boat and ask yourself at each piece of kit, "what would I do if this packed up mid channel at 2am?" and then work out what it would take to fix or at least, work around. Then buy the spares...
I've a liveaboard mate who carries spares for everything, which is nice, even when his engine/shaft coupling broke, he had enough bolts to get us from Lytham St Annes to Beaumaris, when a spare coupling arrived from London.
As before, go round all "critical" systems and work out what could go wrong and what you need to fix it - Voila!
Thanks everyone - lots of useful info for me to work on. sorry question was not very specific - will try harder next time. For info boat is 45 foot yacht - sail not motor - and goal is Med in'09 if I can get up to speed on boat maintenance! Thanks again. Liverpool.
