Standard Operating Procedures


Technical Articles
My Standard Operating Procedures (SOP)

I am sure that some will be controversial but I like to error on the safe side.

  1. Thru Hull Fittings. I always close all of mine if I will be away from the boat more than 24 hours.
  2. Head water thru hull fitting. It is only open when in actual use. (The manual and a placard recommend this.)
  3. Propane Tank Manual Valve. I only have the manual valve open when using propane. Don’t bet your life on a $12.00 solenoid valve.
  4. Water Tanks. I use up all the water from the bow tank first then use the stern tank. If we are not on long trips I keep the bow tank empty. This keeps weight aft unless a long trip is underway and for the most part keeps the water fresh.
  5. Battery Switches. (WindWalker has the start battery on position #1; the house batteries on position #2.)
    1. I never use both unless it is a start emergency.
    2. I always use the house batteries #2
    3. The start battery #1 is only used as a backup or in a test.
    While the engine is on remember to never select off then on. This will probably fry the alternator.
  6. Diesel Fuel
    1. Keep full in the winter to reduce condensation water from getting into the tank.
    2. Always add BIOBOR or the similar to keep diesel system clean
    3. Annually change both fuel filters
  7. HEAD Only use fresh water. This can come from the telephone shower head or modify the basin discharge with the option to cycle grey water into the head.
  8. Man Overbroad. Practice the drill each spring.
  9. Bail out kit. Have a VHF radio, and held GPS and the Flares in a bag in case you need to jump in the dink. ( Our is on Garhauer davits on the back).
  10. Reefer. On long trips with the engine on select full cold. The select back to +/- 4. Also put a ground cover over the food. This traps the cold air.
  11. Be kind to the 1st mate.

Cheers, Dick Walker C-320 (687) WindWalker II 740 Olive Ave. Coronado, CA 92118-2136 619.435.8986

Gerry Douglas Speaks at 2006 Meeting/Regatta


Technical Articles

Gerry Douglas is the designer of the Catalina 320 and the C320 MkII for Catalina Yachts. We were very fortunate that he was willing to take the time to come speak at the 2006 Catalina 320 International Association annual meeting and regatta held in Coronado, CA.

Here is an edited recording of him announcing and discussing the C320 MKII successor to our beloved C320.

SEAWATER SPLASHDOWN PUMP INSTALL


Technical Articles
 

Tag: pump upgrades

When I mentioned to Annie Bennett that I was going to install a seawater splashdown pump, she reminded me that a watering can was a much cheaper way to go! Although I know Annie to be absolutely right not only on the cost but also on the practicality of the watering can approach, I elected to install a splashdown pump and, along the way, learned more about the inner guts of Sea Shadow than I ever would have with a watering can. After running wiring for six cabin fans, the Snake River tank monitoring system to all 3 tanks, and now the splashdown pump, I believe that the only person who knows my boat (excluding the iron beast) better than I do now is the builder.


I divided the project into 5 stages:
  1. pump and strainer
  2. water intake
  3. running the hose
  4. electrical
  5. anchor well.

Coolant Change Procedure for the Yanmar 3GM30FC


Technical Articles

Tag: yanmar

Changing the engine coolant in the Yanmar 3GM30F series Engine This article provides a set of directions for flushing the engine antifreeze in the Yanmar engine. It specifically addresses the Yanmar Japanese Yanmar 3GM, although this procedure should be the same for the European Yanmar 3GM as well. The newer 3YM series might be somewhat different.

Stern Mounted Radar Mast


Technical Articles
Here's an alternative to the Questus when you want to mount your radar antenna at a relatively low height – to see close boats. It has the disadvantage of not swiveling, so you will not see side views very well when heeling over under sail. On the other hand, if there is very heavy fog, I am usually motoring and not heeling. The radar mast was made by Custom Navigation Systems in Westbrook, CT.

Installing a Mast Mounted Repeater


Technical Articles
Here's a Raymarine ST60 Maxiview used as a mast-mounted repeater – so that I can see boat speed as I trim the sails. It also can display any other info that is available on your system - depth, wind speed, etc. The repeater mount was made by Custom Navigation Systems in Westbrook, CT.

Stern Mount Radar installation -Catalina 320

Previously published in Mainsheet, Spring 2003 See Photos in Photo Gallery

Following is a description for the installation of a stern mounted Radar on the 320. I have included a list of what is needed to complete the job, along with some pictures. I will try to provide estimates of the time each step took. If you prepare everything you need in advance, this project can be completed in a day with 2 people. Like many projects, what seemed like a straightforward winter project turned into something of a challenge due to the need to alter some of the standard off the shelf parts for our boats. But if you follow these steps, it should be a straightforward project.
