Wanderlust 3 Sailing Adventure: Latitude 38 Interview

March 2008

Part 4 of 5

38: What was Wanderlust 3‘s fuel consumption like?

Harker: My boat has the Yanmar 4JH four-cylinder with the new turbo and intercooler. I can go at normal cruising speed for almost two hours on a gallon of fuel. It’s a very fuel-efficient engine at 1,800 rpms, which is what I ran it at. Speaking of fuel, one of the great items on my boat - and I’m going to recommend that Hunter make it part of their Mariner Package - is the Fuel Filter Boss. This device allows you to switch between two fuel filters while the engine is running, plus it has a fuel pump which eliminates manual bleeding, and even features a light in the cockpit that warns if the filters are getting dirty.

Thanks to the Fuel Filter Boss, I didn’t get a drop of fuel in the bilge. When the unit indicates a filter is getting dirty, you temporarily switch to the other fuel routing, remove the old filter and drop in a new one - while the engine is running. That’s it. Changing filters was a real pain with my old boat, and I always spilled about a pint of diesel in the bilge. I hated that. The Fuel Filter Boss is great insurance for your engine because all you need to keep a diesel going is clean fuel. I also have a third filter for fuel transferred from the reserve 80 gallon tank to the main 150 gallon tank. Incidentally, Hunter’s normal fuel filters are 10-microns. I bought a 24-pack of 2-micron filters. They stop everything. I never had a fuel problem on my trip and, believe me, I got some dirty fuel in a couple of places.

38: Did you have a watermaker, and how did that work?

Harker: I have a 7-gallon per hour HRO, and it was perfect. I changed the filters five times during my trip, and changed the carbon filter once six months into it. But there wasn’t a hiccup or problem at all.

38: You hardly had anything go wrong?

Harker: There were really just two significant things, and both involved a chain of events. My boat has four 8D AGM 230 amp batteries, which is double the number of batteries and amps that Hunter puts in. So I had twice the battery capacity that the alternator was designed for. Normally, it wouldn’t make a difference, but I had two Danish models who sailed with me from Panama’s Perlas Islands to the Galapagos, so they needed a lot of power for their hair dryers and things. Plus, they used the microwave and other things doing lots of great cooking. Normally, this wouldn’t have been a problem, but my Fisher-Panda had a faulty fuel pump. I carry the F-P Offshore Repair Kit that included a new pump and fixed it myself, but not before burning up the engine alternator. With the girls using the hair dryer all the time, and my genset out, I was having to use the engine alternator a lot to keep the batteries charged. Before we got to the Galapagos, the engine alternator was fried trying to keep the batteries charged.

38: Didn’t you have a spare alternator?

Harker: No. But I do now. It’s a bigger 100-amp Balmar which, by the way, is now standard on all Hunter 49s. The regulators have been upgraded, too.

38: What was the other major problem?

Harker: Having left Cape Town, I was 1,000 miles from Africa and 1,000 miles from South America, when my high water alarm went off. There was a very unusual leak in the water pump housing of my Yanmar diesel that peed water all over the alternator. There was so much that my lower bilge pump couldn’t keep up, and the water got to the higher bilge pump, which automatically turns on an alarm. But because we were heeled over, the water had also gotten into the F-P genset’s motherboard before the alarm went off, so it was toast. As for the main engine’s alternator, it was caked with salt from having water sprayed all over it. Thanks again to a chain reaction, I had no way to charge my batteries for the second time! Well, I have a Honda portable generator that I used to keep the charge up on my engine start battery.

38: We made a big deal asking folks how they would have stopped the leak in your pump. How did you actually do it?

Harker: I coated a self-threading stainless steel screw with 3M 5200 to make it waterproof, and screwed it in the hole. It lasted just fine until I got back to Miami and Yanmar/Mastry had a chance to replace the entire pump housing.

38: What spares did you carry?

Harker: I had a spare and/or spare parts kit for almost everything. I had them for my Yanmar and Fisher-Panda genset, a spare freshwater pump, a spare bilge pump, a spare high water bilge pump and alarm - and, eventually, a spare alternator. I even had a plumbing spares kit because Hunter recommended I buy it. Other stuff they recommended were a spare link arm and U-joint for the steering, a spare Selden gooseneck fitting for the mast and other small parts.
I also got a spare roller fitting for the headboard of the mainsail - I’m terrible at the specific names of things - that I actually needed to put on yesterday. It pulled away from the mast while I was in the doldrums, but I was still able to make it here to St. Barth.

38: It’s a good thing that you didn’t have to go up the mast.

Harker: That’s not an issue, because I can’t go up the mast when alone. By the way, I had to change the masthead tricolor on my last boat twice, so for this one I bought a $700 LED tricolor. It wasn’t cheap, but I think it’s worth it. It’s called a Lopo-Light, and it includes the navigation lights and a five-mile anchor light. It uses less than one watt of power, but is twice as brilliant as the old-style lights, and you never have to change them. All the Volvo Race boats used them. Readers might be interested to learn that I don’t have a single incandescent light bulb on my boat. Everything is either low-power fluorescent or even lower-power LED.

38: You have solar panels. How much did they help?

Harker: I have three panels for a total 28 amps, and during the day they normally provide all the power I need to run everything and to top off the 900-amp bank of batteries. I have two freezers and two fridges, but I only use one of each. I typically used 20 amps an hour, depending somewhat on how much effort my autopilot was having to make. All my instruments and lights use very little power. This Hunter 49 is very well thought out in terms of energy use.
