Live Your Dream. Sail around the world.

it’s NOT that hard – Adventure 37

The long overdue adventure thirty seven is brought to you from the bilges of Nahoa! After a year and a half and over 10,000 nautical miles of sailing our beautiful catamaran needed a little, okay maybe a lot of TLC, and a few changes to make life better.

Nahoa travels on an increasingly tight budget and to extend our cruising budget we do all of the work ourselves. We are mechanics, plumbers, electricians, seamstresses, cleaners, boat builders (lol), painters, polishers and jacks of all trades.

A lot needed attention partly because our plan is to not haul until we are back in the CARIBBEAN. What???!!! Oh yes, our next destination is the Caribbean. Okay we may stop and have a few adventures along the way.

Well, we quickly blew through our plan of 10 days in the boatyard as the project list grew and grew! Aside from all the regular maintenance (engines, bottom paint, sail drives) there were a few other things going on with leaking windows, broken hatches, broken VHF radio, broken inverters, rust in the cooling system (busted water heater was the cause) and so much more… And yet, aside from all of this, our biggest complaint last season, was not enough power. So we procured our new humongous 1.2kw solar array which meant we also needed to move our wind generator mount… you get the idea. A few run away boat projects later and we were three weeks on the hard. Through it all we laughed, cried, freaked out, but we still had a good old time!

So join us as we complete the crazy list of projects that are part of boat life. Below is a full list of what we tackled in the lovely town of Whangarei in New Zealand.

  • Engines and Sail drives
    • Cooling system. Heat exchangers – this was a huge job, if you own your own boat do yourself a favour check/clean these regularly. There was corrosion around the end caps that we had to have fixed and it was painful. These are very very expensive to replace and you don’t want it to get to that point. We suspect Nahoas had been neglected for some time and the pitting around the end caps was bad and the cores were stuck hard.
    • Coolant flush
    • Oil change
    • New propellers – our old ones had started slipping
    • New hot water heater – the old one had rusted out and these are connected to the engine cooling system, so that was causing problems. Not to mention our lack of hot water.
    • Sail drive upper oil seals
    • Sail drive lower oil seals – we do these every time we haul.
    • Dinghy engine maintenance (oil change, etc).
    • Replace some exhaust hoses
    • And everything else that was in the Yanmar maintenance schedule…
  • Power/Electricity
    • One of the things we struggled with last year was power. So that was the one thing we decided was a necessary improvement this year.
    • To extend our solar we had to move our wind generator and extend the frame to hold the new solar panels. We do not weld, so this job we hired out. The fabricators built us a new wind gen mount and extended our existing solar array frame.
    • 4 x 295 watt Canadian Solar Panels.
    • New 3000w inverter – the last one stopped working on us and this is how we get power to the plugs from the battery bank.
    • We are still having difficulty with power when there is no sun and no wind. We are currently looking into new alternators but haven’t yet pulled the trigger. They are crazy money and we aren’t sure which way to go. If anyone who reads this deep into this post has any suggestions, we would love to hear from you! 
  • Comforts
    • Kitchen modifications for crazy improved counter space and insanely more space inside the saloon. We would never have tackled this if it weren’t for meeting a YouTube friend and them knowing a master cabinet maker (Neil). Neil being so kind took care of our modifications in his spare time for more or less the cost of materials. We are so grateful!
    • Glue new veneer of laminate of countertop modification (did you know you can get this veneer 6mm thick for crazy cheap? – if you happen to meet the right people that is).
    • Varnish all of Neil’s handiwork
    • Sew new cushion for bench modification.
    • Mount TV on the wall so it stops falling over in big seas.
  • Water / Sewer
    • New water maker membrane – We weren’t outputting what we used to from the water maker and the taste was off. This is the water we rely on for drinking and it has to be good!
    • Sewage – new toilet
  • Keeping water out
    • Re- seal Escape hatches
    • Replace a couple of seals and a cracked lens on the lewmar deck hatches
    • Re-seal front saloon windows
  • Outside Maintenance
    • Buff/wax gelcoat
    • Fix Gel coat cracks
    • Polish stainless
    • Varnish outside table
  • Rot Prevention
    • Antifoul. Sand & Paint.
    • Corrosion
    • New Zincs
  • Sails / Rigging
    • New main. Straight forward but mainsail bag was too small.
    • Replace Genoa furler. It was starting to seize in rough conditions.
    • New main halyard. Ben goes up the mast on this and it was looking seriously bad for wear.
    • New Code Zero. We blew ours up on the pacific crossing. Also reinforced the rigging with metal backing plates.
    • Rig inspection
    • Replace standing rigging toggle where it attaches to the boat due to stress cracks found.
    • Service all winches.
    • Clean mainsail track and lube it up
    • Rotate mainsail head car so it doesn’t blow itself up…. Again.
  • Ground Tackle and Steering
    • Re-galvanize rusting steering arms
    • Re-galvanize rusting Anchor.
    • Flip anchor chain end for end and re-mark all depths
  • Communications
    • New satellite antenna.
    • Install iridiumGo satellite communications puck
    • New VHF radio
    • New badelf GPS puck

Hey guys!
Stumbled across your videos on youtube, and now I am hooked. Do you have a vlog on buying your boat? I am pretty sure your Cat is a Lagoon 40 but what year is it?

    Hey Tim! Glad you’re hooked. It’s a good addiction trust me. We weren’t Vlogging when we bought the boat. Just Blogging. Not as good but better than nothing. Just found one of those first posts. You can find it under ‘Posts’ or click here. Also just noticed the pics aren’t properly loading unless you click on them. I guess I’ll fix that soon!

Curious about the alternators. How are they performing. How many hours on them. What size is your battery bank.? Lead acid or lithium? Are they 100 amp alternators? Bad regulators or noisy bearing?

    Hey Rex! Thanks for the questions! Here’s a couple specs:

    We have the original Hitachi 60amp alternators that shipped with our yanmar 3jh4e. They have external regulators (Sterling ProRegD) set to AGM (no lithium option).
    We upgraded to a 600 amp hour Lithium battery bank (spec sheet below) a couple years ago thinking that would solve our problems. But I think we either killed our alternators (because lithiums are hard on alternators and they overheat) or the external regulators don’t know what to do with lithiums.

    What do you think? Bad alternators? Incompatible external regulators? At peak performance (2,000 – 3,000 RPM) we are seeing max 15amp output from each alternator. I am torn because buying new external regulators (with a lithium setting) may just burn up these stock alternators. On the other hand, we’re considering some high output, lithium compatible, alternators from Mark Grasser. Expensive considering we need a pulley kit. Essentially that would run us into the 5-6K mark.
