What Boat Tools for Circumnavigation?

Well that depends...

I have been asked a few times “What are the best boat tools to have on a sailboat?”

The short answer: Well it depends…

It depends in part on

  1. how much you want to do yourself
  2. what systems you want to work on
  3. how good your Rolodex is to find qualified workers
  4. how far away you will be from someone who has the tools and knowledge

For Golden Glow I like to have the tools needed to maintain, break down, reassemble and fix every system on the boat. Okay, maybe I won’t be able to remove and replace a whole engine, but I’d get close.  We carry a lot of weight in tools, in fact between the tools and the weight of our toys it is amazing that Golden Glow has any freeboard left at all. But each has it’s purpose and with the difficulty in finding consistent, quality workers, they are worth their weight in gold.

If you are filling out your boat’s tool box, here are some Golden Glow thoughts on the subject. I have also included some pictures of some of the cool tools I find helpful on board.

Here are the questions I would ask yourself to determine what boat tools you might want on your boat:

  1. What boat systems do you want to maintain, repair or install yourself?
    Hooked Awl Tools for Sailing

    Cool Boat Tool – hooked awls / picks used for pulling hoses off barbed fittings and for lifting Racor filters and can be helpful with pulling impellers.

    A critical step in determining the specifics of a tool-set is to review all the systems you have on board. The specifics of “must have” tools will reflect the systems you have on your boat. For example our in-mast electric furling cover requires a T50 torx to get proper access to grease the inner bearings. I think that is the only T50 torx on the whole boat.  So that tool would not be needed on a sister ship without an electric in-mast furling.   To determine the specifics for nut/bolt/screw type and sizes for each system you will need to review each of your systems.  For now just a list of the systems is enough.  Your list could include items like: engines, genset, outboard, watermaker, winches, shaft/prop assembly, rudder drive linkages, water pumps, bilge pumps, sump pumps, toilets, stoves, ovens, toys and the all important blender, etc.

  2. What level of work is to be performed on each system? Once you have the list of all the systems on your boat, then decide if you want to:
    a) just do maintenance on system,
    b) do minor repairs,
    c) do full repairs,
    d) be able to install and remove the system.
    If you want you could mark each of the listed systems from #1. above with a letter a through d in #2. Be sure to check your spare parts list and determine that you either have the tools to make the repair, or expect you will have access to the tools and or expertise in the area that you sail.
  3. What tools are needed for your level of work on each system? Determine if you are competent to do what you have listed.  If so, you can reasonably determine what tools are needed to do the type of work on each system.  If you have not previously done the work on a specific system there are a couple ways to determine what tools you may need.
    a) get a copy of the service manual(s) for the system.  These typically will be geared towards dealers of the product and may have many versions.  Some are available online others are more difficult to obtain.  Better manuals will have a list of tools needed.  Be sure to check for mechanical and electrical versions of manuals.  Check for service manuals, the operational manuals often do not have the detail to assess tools.
    b) hire a professional to come on-board and do a “training” hour with you.  Be sure to ask what problems they see most often on each system, how to resolve them, what spare parts might be most likely needed, and of course what special tools are needed.  Have them go though your tool kit if unsure.  Definitely ask to look in their tool box and ask questions of any tool you don’t have.
    c) you can just start on a project while near a reasonable tool store and prepare to run out and get what you don’t have.
  4. Finally, take a safety inventory, some tools are unique to dealing with emergencies.  For example during crossings I keep a couple of charged batteries and a portable grinder with a diamond saw blade installed for cutting stainless in case I have to cut any stainless cables / shrouds. We also have a bolt cutter as a worse case back-up.  Grab bag tools and medical tools are both worth a review as well.

When buying tools for the boat, I normally get professional grade, high impact, rust resistant with the longest warranties I can find (for life is good).  This helps insure the tool will work when you need it.  (Note on maintenance: tools need to be maintained. Keep them clean, oiled and organized for longer life).

Here is a rough boat tool list of what is on board our Antares 44i ‘Golden Glow’, listed by category:

  • Everyday Boat Tool List (kept in a drawer for easy access)
    Cool Tool 2 clips and a glass

    Cool Tool for holding items for soldering or gluing on a rocking boat. Also good for checking out Grinch hearts.

  • Mechanical/General Boat Tool List (kept in one or more waterproof plastic tool boxes and perhaps one small canvas bag for taking tools to the project.)
    • Sockets, ratchets and wrenches: both imperial and metric sizes to fit systems as outlined above.  Include extenders, ratchet drive size adapters, bars, and universal joint adapters for 1/4” 3/8” and 1/2” drives.  Deep well sockets that are professional grade strength are worth the extra cost. Wrenches should be both open and closed end. Quality universal joint adapters and flex drives can help with accessing hard to get nuts, bolts and screws helping to minimize the amount of dis-assembly needed to access that hard to get nut.  These also help minimize the blood loss.
    • Crescent wrenches (3 sizes to span maximum bolt size) check drive shafts for large nut sizes.
    • Vise Grips: large and medium regular with needle nose and clamp nose.
    • Pipe Wrench: 10″ and 20″ (length based on access to systems)
    • Driver Set to take complete driver tip set for slot, cross, square, hex and  torx heads.  Flex shaft for attaching to electric drill good for reaching hard to get to locations. For Philips: a #1-#4 in long handle and #1 and #2 in short handle For slotted or flat 3/16″, 1/4″, 5/16″, 3/8″ long handle and short handle set.
    • File set:  (at least flat, rounded in fine and course and small & large diameter rat tail)
    • Awl and punch set with hook awls (good for removing hoses)
    • Cold chisels various sizes
    • Tap and die for tread type and diameter of most used bolts on your boat (hat tip: Bob)
    • Hammers: claw hammer, rubber hammer, small sledge hammer
    • Pliers: heavy duty pliers (at least 2 sizes), channel locks (3 sizes), needle nose pliers (several types/sizes I carry 8).
    • Snap ring pliers for inside and outside with multiple bits
    • Bolt Cutter
    • Crow Bar: flat and round
    • Clamps: c-clamps, bar clamps, flex clamps, ribbon clamps
    • Wire brushes: brass
    • Heat: butane blow torch, lighters
    • Metal snips (diagonal and strait cut)
    • Feeler Gauge
    • Rivet gun
    • Snap and grommet punch and die
    • Marlin Spike
    • Set of Fids

This cup does not runnith over.

The telescopic back scratcher is very useful but the cool tool is the non-skid magnetic cup for holding screws and stuff on windy rocking decks. That is a utility tool held upside down in the cup: strong! No more screws gone swimming.

  • Sewing Kit
  • Mirror on telescope
  • Magnetic parts cup
  • Assorted blades and grinder discs for power tools
  • Ax/Hatchet (for safety, and emergencies like getting wood to build a bonfire on the beach)
  • Pulley puller / propeller puller
  • Pump, gauges and valves for changing and testing freon for the fridge/freezer units.
  • Consumables like sand paper, paints and sprayers, that make a difference, i.e.. I carry a paint can of the Volvo-green to spray any new part so the engine keeps looking like new.
  • Construction Boat Tools:Portable tools are best if all use same battery and charging system. Higher voltage systems are normally more powerful.
    • Drill and bit set to include metric and imperial drill sizes up to 2.5″ hole cutter.
    • Circular saw and blade set
    • Jig Saw and blade set
    • Skill Saw and blade set
    • Grinder and disk set, include sanding disk and diamond cutting disk.
    • Multi Tool and set of cutters and grinders.
    • Buffer and pads
    • Sander and pads
    • Saws: hack saw and blades, copping saw and blades, wood saw.
    • Vises: small and large
    • Wood chisels
    • Working block (wood) for drilling and cutting on and cutting pad (plastic) for smaller projects.
    • Chisels.
    • Drop light and 120v extension cords.
  • Electrical Boat Tools:
    • Soldering Iron
    • Crimpers
    • Wire cutters/strippers
    • Electricians pliers
    • Heat gun or hair dryer for shrink tubing
    • Smart volt / amp meter
    • Utility multi-arm vise
    • Lead tape unless all electrical runs already have pull lines
    • Supplies: electrical tapes, solders, fluxes, shrink tube, wires, connectors, fuses, tie wraps, mounts, liquid electrical tape, etc.
Cool Tool: Telescopic Mirror

Big Head Problems? This telescopic mirror “cool tool” is great for getting a view to where your head (and phone camera) just won’t fit. Like getting the serial number off equipment without having to remove it to see the back.

  • Maintenance Boat Tools: I have small tool sets for frequent jobs like changing oil and fuel filters.  Examples include: changing fluids/filters each of our 4 internal combustion engines: funnels, vacuum pump and hoses, pans, hooks, filter wrenches. Fiberglass maintenance: buffers, waxers, power washer, wet dry vac. Battery tools for specific gravity and a pump for filling water into wet cells. Paint and putty knives and buffers and all the cleaning tools.

We also have a few fishing tackle boxes with specific pliers, knives and tools for maintaining reels and least I forget the blender: the tool of sundowner happiness… cool drinks do rule and every once in a while I hear the chant for Monkey Madness. We found a 12 volt blender on Amazon that was half the cost as the same blender in the chandleries on St Martin.

Blender aside, the real answer to what tools do you need on a sail boat is “it just depends…”

NOTE: updated parts list on Aug 25th: wood working chisels, pulley and prop puller, feeler gauge and more specifics on screw drivers

  1. thanks Rand to buy antares is my goal,,,,but now too expensive for me,,,2 yrs ago, the aussie dollar was worth 1-07 now its worth 74cents,,,,im useless with my hands,im not a tech guy,,

    • Hello Peter, thanks for the note. Yes, Antares is a great vessel, and getting better all the time. Nice thing about exchange rates is they change over time, and as more Antares are built you will have more countries to consider exchange rates with. Near the time we bought ours, another was being bought in Europe (Euro I believe). Best way to learn how to use your hands is to use your hands! I learned by holding flashlights and passing tools when a child, never too late to start and I am certain there is a mechanic somewhere right now that would LOVE to have better lighting and the right tool handed to her/him. Look forward to seeing you on the water!!

  2. Thanks for a great list. What about spares for each system?

    • Hi Johnny, Yes, we carry many spares and the ideal list is unique to each boat, it’s systems, the type of sailing, the crew and the location that you are in, and of course the tools available to actually install the spare. As we are on a long term voyage I keep certain parts on the boat and others on land that I use to replenish the boat. I have started a post on this subject and will post sometime soon, until then I can say that manuals, mechanics, forums and past history / log books are good ways to determine what you need and one way to prioritize is based on safety factor if loss of system, failure rate, weight, cost, size, and availability in your cruising area. Ultimately, IMHO, a well maintained boat with fewer spares is far safer than an ill maintained boat, no matter the spares.

    • Hi Johnny,
      Here is a link to a a blog post on the subject of spare parts:

    You are right, preventive maintenance will save you a lot of work and above all, lots of money, not to mention the peace of mind that comes with. There are certainly better things to do at sea instead of costly repairs

  4. I also carry a full tap and die set along with deep well sockets. Many times when I have asked someone for help, I have the tools they need which saves me time and money from them having to go to their truck or come back another day. I also agree on the statement of ask to see the tools the tradesmen have as that’s how I continue to add to my supply. I may not be able to fix it, but I don’t have to wait for a tool to get it fixed! Great list.

    • Hey Bob, great suggestions, I like the comment of saving trips for the tradesmen. I have pondered getting a tap and die set, and have been slow to pull the trigger: is there a “most used” range of thread type, diameter and standard you have found use for? I will add that to the list as an option. Will add the “deep well” to the list too, we carry those on Golden Glow and have been thinking of getting rid of the standard set, as I have yet to find a place the longer length of the socket is an access issue. Though expect I will as soon as I get rid of them.

    you must have read my mind,i have been wondering about tools ect for repairs and maintenance.for when the time comes when I buy my cat,
    would love to hear about the repairs that iu carry out in the future,,,and what was the causes of the repairs,,,,,
    may the breeze always be in ur back.

    • Hello Peter, I’m glad we can offer some help. So far we have done many, many upgrades and super attentive maintenance, but Golden Glow has had only two problems: one was a worn out part on our watermaker, that we replaced. The other a short in our main furling electric engine, that was caused from wear inside the mast against a cable. That was easily fixed once I found it. Both very minor issues, so all in all we have (knock on wood) not had any serious repairs. Having said that I spend a lot of time on preventative maintenance, so the work is definitely there, just proactive. Thanks for the comment. Best breezes to you too and best of luck in your catamaran shopping. Check out Antares (, we love our 44i and could find no better fit for our couple’s world adventure.
