Composit Rudders

Here is the thread I mentioned where Bob Perry discusses carbon fiber rudders: http://forums.sailinganarchy.com/index.php?showtopic=80490&st=0 Here is a link to a specific message in the thread where Bob included his design for a carbon rudder: http://forums.sailinganarchy.com/index.php?showtopic=80490&st=0 In response to my question he guesstimated $7K to $9K for a cf rudder but suggested contacting Phil’s Foils.

Shakespeare TV Antenna

The original TV antenna provided with La Mariposa in 1998 was an analog type that is no longer useable due to transmitting stations changeover to digital transmission. This analog TV antenna was removed from top of mast and not replaced. Coaxial Cable is still connected from chart table behind VHF radio all the way to the top of the mast where cable exits the mast. The Antenna bracket is still on top of mast. I have replaced the analog antenna with a Shakespeare omni-directional marine TV digital antenna. The picture quality is terrific and the signal does not degrade as the boat swings on its mooring because of the antenna’s unidirectional feature. I am now receiving “over-the-air” reception on the boat’s Sharp flat screen TV, model LC-19DV-12U. I am using 117 VAC power to drive both the TV and antenna. I use an inverter. The antenna’s power selector (12 VDC

Dim glowing of Reverse Polarity Light

When using my Honda 2000 generator, I noticed that the reverse polarity light glows dimly. Tom, The reason you see the reverse polarity light glowing is because the Honda generator has a floating ground, meaning that there is no connection between neutral and ground, like your shore power connection has back at the service on shore. If you want to eliminate the flicker, and operate the generator more safely, where you’re GFCI outlets trip on fault, make up a plug with jumper wire between the ground and neutral and plug it into one of the generators AC outlets. Jim Turner “Makana Kai”, 2000 C380, #227 LEDs are low voltage (about 2-4 v), low current devices and so require a series resistor to drop typical circuit voltage into their range, thereby also limiting the current to reasonable (operating) values. The 25 k resistor referred to allows the led to operate near

Engine Compartment Cooling

Jim, May be able to suggest a way to improve the air circulation and cooling in the engine compartment. I’ve been holding off installing the larger Ample alternator and Balmar regulator until I could figure out how to improve cooling in the engine compartment. Last trip to the boat I completed replacing the flimsy ventilation hoses with nearly indestructible Hi temp thermoplastic rubber duct hose and rerouted the positive ventilator discharge duct from under engine to top of engine and alternator to scavenge rising heat more effectively. I’m heading up to the boat Wednesday and should be able to complete a number of projects, including rewiring the blower to automatically run when the engine is running, and for a 15 minute cool down period after shut down using a delay board (should be able to re-utilize the fan switch as an off switch). Then install the alternator, regulator and sensors.

Engine Stalling Problem – Discussion

My westerbeke 42b has run for years flawlessly. Several days ago it began to stall. Suspected it was starved fotbfeul and I raced primary an secondary filters. They came out black and grimy. Since then engine still stalls after running at 3/4 throttle for 15 minutes. Seems starved for fuel. Any ideas?   Check that the electric fuel pump is working. I had a loose connection on the fuel pump wiring that caused a similar problem. Fuel pump should click during glow plug operation and when the engine is running. Paul McManus Sea Sea Rider C380 #185 Port Orchard, WA   I had the same problem. It was a clogged fuel line with lots of gunk inside the fuel tank. You will need to clean the line and the tank, and replace both filters. I had the work done by a mechanic. He also recommended a fuel additive to prevent

Replacing Hot Water Heater – Discussion

I’m heading up to the boat tomorrow to knock out some projects before going sailing we have friends join us for Labor day weekend. Â My top priority is to replace the 12 year old hot water heater, that has sprung a leak. Â I did thoroughly check for leaks at connections and pretty confident it’s time to replace it. I’ve purchased a Quick Nautic B3 3012SL, 1200 Watt, 8 gallon stainless steel tank boiler to replace the Seaward F1100 with it’s 11 gallon aluminum tank. Â I found the following comment on another blog which really resonated with me, since I also replace the seaward boiler on our Catalina 30 after it started leaking as well. “Atwood, Force Ten (Kuumha) & Seaward’s – These square water heaters look to be all made by the same company and re-badged. They all feature a stainless steel JACKET but an ALUMINUM tank!

What Color is Your Exhaust?

I came across this on another Catalina site and thought it would be of value to our members as well. The following analysis comes from U.S. Master Marine Surveyor Rob Scanlan and is presented courtesy of RCR Yachts. Key-numbers as to how likely the problem: [1]-Very Common. [2]-Common. [3]-Possible. [4]-Rare. [5]-Very Rare Black Smoke is caused by partially burned fuel. When the fuel/air mixture increases there is insufficient oxygen present in the cylinders to complete the combustion process. Large quantities of carbon are then produced which appear from the exhaust as minute black soot particles. Engines with turbochargers have additional sources of black smoke. Black Smoke Insufficient Air: Causes: Air intake filter clogged [2] – Air intake restricted [3] – Exhaust restricted [3] – Leaking inlet or exhaust valves [4] – Poor engine room ventilation [4] Black Smoke Excessive Fuel: Causes: Defective injector(s) [1] – Incorrect injector nozzle [3] –

Experience with Honda Generator

There has been considerable discussion recently on the use of a Honda 2000 generator to power AC units when not connected to shore power. Having just purchased one, here is my experience. Note that this was for a 387 with two CruiseAir AC units, a larger one for the main cabin and a smaller one for the stern cabin. First, the generator had no problem running the stern AC unit. Unfortunately, the stern unit couldn’t deal with the whole boat when at anchor in the 90+ degree afternoon’s sun. We didn’t try it at night. Second, the generator could run the larger AC unit as long as it was the first time you ran it that day.  What you can’t do is to let the compressor stop and then restart it. That causes an overload on the generator. (Updated: 8/19/2013 – I installed a Dometic SmartStart to the main
