I got back from my summer trip but due to weather and crew problems we only
got as far as Queen Charlotte Straits. It was a great trip and I have no regrets.. I don't regret any time I spend aboard my boat. Here are some observations and lessons learned. Total trip= 793 nautical miles. (from GPS track) Fuel used= 66 gal. Eng. Hrs. = 165 hrs. (from log, engine meter was unreliable.) Motor/Sail % = 95% Water used (crew of 2) = 160 gal. Trip duration = 28 days Days at dock (Comox, BC) = 2 Comment on Redundancy of Equipment: Prior to leaving and realizing the my Aries is worthless while motorsailing, due to prop turbulence on vane servo oar. I upgraded my ole reliable AH3000 AP control to a ST5000 (mfg refurbished) control on an Alpha heavy duty linear drive. I retained the wiring and mounting plugs for the old AH3000 and linear drive. During Sea Trials to calibrate the ST5000, the control failed and would constantly trip the 15amp breaker (even with the drive disconnected). I was unsure if the little AH3000 would survive the power demands of the Alpha drive, but I insalled it with a 5 amp circuit breaker between the drive and the control head. This worked fine and to my knowledge, the breaker never tripped/reset. The control head never complained and this Alpa Drive (looks like a domestic gate opener) handled the very have tiller load in all conditions. (My Ingrid is close to 14 tons with a stern mounted rudder and 6ft tiller.) I'm still planning to upgrade my course/computer to get some of the AP interface features but now considering a core/pack below deck computer with a handheld remote control unit. (I already have the ST600R and plug-ins in several locations, left over from the ST5000 installation.) I doubt I will find any electric linear drive as power full as the Alpa Drive and I don't want the complication of the hydraulics in the open cockpit. As mentioned in much earlier posts, I have an 800 AH battery bank (4 ea. Trojan LH-16 batteries). I also have a 2000watt inverter/140amp charger. The primary load on this battery bank is a small frig and a small chest freezer. Both have had their insulation upgraded. The frig and freezer are both Norcold, however, the frig runs directly off 12 volts. I have had problems getting the freezer to run off 12 volts (voltage drop and constant circuit breaker trip) and run it on 110volt AC off the inverter.. This is a was to power since the inverter must be left in "Sense Mode" which has some overhead. Another reason to leave the inverter in "Sense Mode" is the for the power converter for the Laptop. In fact any charger will cause the sense mode to activate the inverter with even higher overhead. I have two 56 watt solar panels with worked surprisingly well in the PacNW and a WindBugger wind generator which can produce up to 15 amps in 25 knot of wind and averages about 5-10 amps in less wind speed. I have been playing around with several high amp automotive alternators for the past couple seasons. The fields of these are controlled by a Weems-Plath AutoMac II. It can handle any size alternator as long as the field current is more than 10 amps. I set off with a 120amp Delco installed with twin Vee belts. I was able to get 70-90 amps from this but the front bearing on this one failed after about 80 hrs. I then installed a 100 amp Delco and was able to charge at about 60 amps for another 80 hrs when it died from over heating (I suspect). For the last 30 or so miles of the trip I ran on the old OEM 35 amp alternator which was no match for the large and partially discharged battery bank. I kept the charge current low to prevent it from failing. Lesson learned: (1) Look for a Balmar 200+ amp alternator. (2) forget the freezer and carry a smaller supply of meat in the frig (not worth trouble). (3) Listen to the warnings from others in this forum. Minor problems/equipment failures: (1) Engine hour meter. I'm on my 2nds one in as many years. The current one runs fast some days and slow others. I have been taking totals form my daily log entries. (2) OEM engine alarm module failed (false alarms after ~30 min.) $140 for replacement (forget that, go aftermarket for $40) (3) Fuel transfer meter/totalizer fails (sticks) after setting idle for several days. I took it apart several times and suspect that an O-ring seal is swelling up to tight around the shaft. Even though I can get it to work, I have gone to timing the run time and calculating the amount of fuel transferred. I made the entire trip on the fuel I had onboard, found there were not fuel discounts or non-road tax fuel in Canada. OH! Yah! I should have purchase and additional supply of diesel before I left and had it available to refill my tanks on return.. I could have saved $64. (At departure I paid $1.95.9 for died fuel and yesterday I paid $2.59.9 some for my tractor.) I'll wait a while to refuel the boat. Still have about 25 gals left onboard. I still have enough canned/dry goods onboard for another trip or two. Really overstocked. I probably took more tools that most, but then for a DIYer you never can have too many. Never found a problem I couldn't fix with what I had. Same with engine spares. My Volvo MD2B ran flawlessly,as I expected. (it was installed new about 200 hrs ago). The current 3 blade 17X11 prop worked great however I may have about an inch taken out of the pitch so I can get a couple hundred more RPM. Hull speed of 7.5 were attainable at 2000 rpm (not bad for 25 hp pushing a full keel 14 ton boat). Well that's enough for now. Good to be home but I do regret that I couldn't visit the sites in Alaska. I plan to revisit Queen Charlotte Straits next year and beyond.
