Superstructures, Rudders, and Thrusters..Oh My!!!!

This is the first opportunity that I have had to see the superstructure mold uncovered. This thing is huge. Well, I suppose by mega yacht standards it's not, but this is all one piece that includes the fore deck, Portuguese bridge, cabin sides, starboard walk around deck, stairs, cockpit, etc.
Here is another shot of it. That is the forward port side hawes hole insert. (Remember that this is the reverse of what the part will look like and it is upside down).
This is Patrick getting ready to install the engine room vent insert. Patrick is our infusion expert and heads up all lamination for us.
The preparation of this mold part took months as it is so complex. If you look carefully (click on the picture to enlarge it) you will see the side windows for the saloon. There will be inserts installed to form the rounded bedding surfaces. They will begin "dry stacking" this part in a few days and we hope to have the finished superstructure out of the mold in a couple of weeks.
Meanwhile, back on the boat they are fitting the bow thruster. With dual 5 blade props we should be able to do pirouettes in a gale. Well, at least look good while docking.
This is the mounting plate for the thruster. ABT really builds a robust unit. The hydraulics we have selected are supposed to provide plenty of thrust power even when the engine is at idle. Sometimes hydraulic systems are undersized and you have to rev up the engine to develop enough hydraulic pressure (and volume of oil) to make the thruster effective. Remember, the thruster on the standard boat is electric....hydraulics are an option.
The Village Marine Watermaker and 2 of the A/C units are shown here being fitted in the engine room. These are not permanently installed yet.....just checking the fit. There is one more 20,000btu A/C unit that will go in between the watermaker and the other 2 A/C units. These are optional items. We are installing the A/C units as our first trip is to the tropics. All boats are pre-plumbed and wired for A/C and Kabola diesel heating.
This blog entry is of events over the past couple of weeks. This was taken today showing that the engine and other previously shown equipment has been removed so that they can gelcoat the interior of the engineroom before permanently installing the equipment. I think you may need sunglasses in the engineroom as it may be very bright with all the white gelcoat.
Fitting the upper and lower rudder bearings is a very exacting procedure. Here you can see the jig that is used for alignment.
The rudder is ready to be installed. The articulating rudder comes standard on all of the Northwest Trawlers. The rudder will allow the boat to turn a circle in not too much more than its own length.
One thing that has delayed us a bit is the final design and fabrication of the BAT drive mounting system. Today the bracket was completed and installed on the transmission. I will show the complete installation as it is completed. The BAT drive is the "come home" system that powers the main shaft hydraulically from the generator in case of main engine failure. The advantage of this type of system over a wing engine is the thrust of the main prop over the rudder (articulating in this case) will allow the skipper to bring the boat into the wind and waves with no forward way on, just prop wash over the rudder. Wing engines with small folding props are quite ineffective in providing forward way which in times of heavy seas and high winds may prove it difficult to get the bow headed into the seas. The BAT drive will give us peace of mind for our upcoming journey. (see prior blog for details)

Tanks.....but no tanks....

The main fuel tank is resting in place. They placed it in the boat to verify it fit and also to see where the aux tanks need to go. The tank has been pressure tested to 2 lbs and it held the pressure overnight. The tank will be removed and all the fittings permanently attached before final installation.
Phil is measuring and marking the aux tank covers. These are structurally strong enough to support the weight of auxiliary equipment such as air conditioners, water heater, etc.
I caught Don as he was placing the forward bulkhead in place. This is the bulkhead between the forward master stateroom and the anchor locker. There will not be any access to the anchor locker here as we want to eliminate any chance of water or odor intrusion into the stateroom. Have you ever sniffed an anchor locker???? Not pleasant. This will be a watertight bulkhead.
The main tank has been removed to prepare it but here you can see the other aux tank in place along with the port side bulkhead that separates the galley from the pilothouse. Also visible is the crossover exhaust that Stan is fabricating. A custom heat shield is being ordered that will cover the dry stack portion.

I swung by our other location and visited the woodshop. Dan Thompson has things well underway there for the interior cabinetry. Here are a couple of pre-cut panels drying in the spray booth. All of the panels have been engineered and cut so that it should be just a matter of assembly and bonding once the hull is ready for the interior build out.

The superstructure mold is finally finished. The laminating crew will begin the layup this week and if all goes according to plan, we should have the superstructure ready to be built out within a couple of weeks. I will try and get some photos of the process.

More to come............

Continuation of Yesterday......

The generator arrived, a Northern Lights 12KW unit. At the right is the power take-off cover. We ordered this option because of the BAT drive that we are installing. We may also cross plumb the BAT drive hydraulic system to the main hydraulics as a backup in case of failure.

Here is a shot later in the day with the genset in place. Note the very thick Soundown on the rear bulkhead. With the sound shield on the genset, we hope that it is whisper quiet. The Centek muffler is to port (we are looking aft) of the genset. This one is being customized here but on future boats we will have Centek manufacture the muffler to our exact specifications.

Details.....Details.....

There seem to be a lot of details that are getting attended to. The plumbing under the forward lower deck is complete so now Dave and Phil can position the deck so that Greg can bond it in place. The Lifeline batteries are in their position in the Lazarette. There are 4 for the house bank, 2 for the inverter bank and the 2 (4D) batteries are the main engine start. There will be another group 31 battery for the generator start. This boat is being equipped with hydraulic bow thruster and windlass; otherwise there would be 2 more 8D batteries forward to power the electric windlass and bow thruster. The Lifeline batteries are AGM (Absorption Glass Mat) type. From Lifeline's website:

LIFELINE MARINE BATTERY BENEFITS
  • User Safe
    sealed construction
    non-spillable
    install in any position if properly supported.
    submersible without damage
  • Maintenance free (no adding water or repairing corroded terminals)
  • Fastest recharge. (no current limitations with voltage regulated recharging)
  • Deep Cycle (thick positive plates to provide real deep cycle performance)
  • Outstanding cranking performance (aircraft cell construction lowers internal resistance)
  • Best charge retention (especially against flooded cell types)
  • Lowest discharge rates (Less that 3 percent per month unattended)
  • Easily shipped (even via UPS except GPL-8D and GPLAD because of weight)
  • Shock and vibration resistant. (100% of plates are covered with separator liners)
  • Properly supported, LIFELINE AGM batteries with absorbed electrolyte can be installed and operated on their side.
  • While Lifeline AGM batteries are significantly more expensive than standard deep cycle, we feel that the benefits far exceed the cost. When you are on the hook in remote anchorages it is reassuring knowing you have a robust, trouble-free, battery bank. There will be a cover over the batteries that will double as a storage shelf for the odds and ends that get tossed into the lazarette.
    The guest head enclosure is being bonded into place. The area behind will give good access to storage.
    Here you can see the port side auxiliary tank. Since we will be transiting south and through the Panama Canal on the first voyage, we want to be sure that we have sufficient fuel supplies so that we can limit our stops. We hope to go from La Paz to Panama City with only one fuel stop.

    I am running out of time today but I will try and get some more pictures posted tomorrow.

    FUBAR Plus

    Some months ago my friend Bruce Kessler (Spirit of Zopilote) asked me if I would put up a sign in our booth at Trawlerfest in Solomons, MD. Always willing to help a friend, I said: "Sure". The sign was the first public information about the upcoming FUBAR Odyssey (see sidebar for link to their website). The FUBAR Odyssey is to be a powerboat rally from San Diego to La Paz, Mexico beginning in early November, 2007, Well after talking to Bruce I got to thinking what a great idea it would be to enter our new Northwest 42 in the event. Then I got thinking further and thought what a great idea it would be to take the boat on its own bottom from Seattle to San Diego. Then I got to thinking what a great idea it would be to take the boat to Stuart, FL for Trawlerfest, 2008 on its own bottom. Well at first my wife (Jan) didn't think that I was having a string of "great ideas" but now after talking about it, she has gotten excited as well. In fact, the whole team building the boat is excited.

    Well, the decision to do this is not without causing extra work. We essentially have had to re-organize the engine room because I wanted to have extra tankage aboard so that we could make longer runs without having to refuel. The boat with standard 600 gallon tanks has a range of about 600 miles at 10 knots and about 1000 miles at 8 knots. I would like to have a margin of error so we are increasing the tankage by about 50% and adding another 300 gallons or so. So back to the drawing board.....er computer to make sure that we don't upset the CG (center of gravity).

    Anyway, we are now saying we are doing the FUBAR Plus.... Our scheduled itinerary is as follows:
    • Depart Seattle 9/17 at the conclusion of the Seattle Boats Afloat Show
    • Arrive San Francisco 9/21
    • Depart San Francisco 9/28 after a week of visiting old friends and letting interested people in the Bay Area see the boat
    • Arrive San Diego 9/30
    • Depart San Diego in the FUBAR Odyssey 11/7
    • Arrive La Paz about 11/27 with many stops and cruising parties on the way
    • Depart La Paz 11/27
    • Arrive Acapulco, MX 12/1
    • Depart Acapulco 12/3
    • Arrive Puntarenas, Costa Rica 12/8
    • Depart Puntarena 12/10
    • Arrive Panama City 12/12
    • Depart Panama City 12/14
    • Arrive Cancun 12/18
    • Depart Cancun 12/20 (Do we really have to leave???)
    • Arrive Fort Lauderdale 12/23
    We will spend a month or so in Fort Lauderdale because our representative there, Judy Waldman, has several people lined up to do sea trials and inspect the boat. We will arrive in Stuart, FL in time for Trawlerfest. After that.......who knows?

    If any of you have any suggestions or good ideas (other than "are you nuts?") please either comment here or send me an email.
