The Adventures Of Botany Bay

Latest News:
July 18, 2013: Topped batteries with distilled water half way up cut under cap. (Max fill) none of the cells were especially low compared to others. Total added water was just under a gallon.

July 17, 2013: Talked with Carter at Riley marine, initial estimate for the entire job is about $500, recommend a $400 deposit on credit card. Will seperate repair from improvements on individual bills. Should be finished next week sometime, Tom will plan to pick up when they call.

July 16, 2013: Tom dropped off the stainless with Riley Marine Carter called and noted that the wall thickness of the stainless is a bit thin and will require doubling for the repair in any event. He recommends sleaving as far up as possible down to the base. Including reinforcing the undamaged gate stantions. 0.049inch wall thickness with 1" tubing. Carter recommends doubing with 0.065 stainless tubing which will just fit inside for a total wall thickness of 0.114 giving a much stiffer tube.

I talked to Oyster  via e-mail and they also recommended reinforcing all of them. I was concerned that the wall thickness was to ensure the tube bent before anything else making the repair purely on something which is easily removed. That may have been the concept at the time but at this point they would also recommend doubling.

July 14, 2013: Additional maintenance: Verified no leaking seacocks &dried out fridge/freezer after ice melted

July 13, 2013: Pulled three stantions, 4 gates, two bases to send to the welding shop.One base is in good shape as an example, two of the gates are in good shape and mirrors of the other side. Tom is taking it all down to Riley Marine early next week for straightening after someone bumped me while I was tied to a mooring. No serious harm just minor repair

Ran engine and generator for about 15 min to oil everything up prior to heading off for a two week vacation in Sweden.

Tightened large PVC reducer on bottom of water manifold off of the main tanks. This spot has been damp and probably the source of the remaining water coming into the bilge (except when it rains, then some comes down the inside of the mast)

Bilge is now dusty dry!

Main seacock, individual valves on sea chest closed for the duration; Remaining 1.5 inch blake seacocks closed; Fridge and freezer defrosted;Toilets treated with odorlos; New desicant hangers all through the boat (18 of them total), these work very nicely keeping the boat dry when closed up; sucked about half a cup of water out from under fridge (is it perhaps frost on lines which thaws and drips down under the fridge) thank goodness for installing the line to suck the water out of the low spot; No moisture under aft toilet, or under aft shower.

July 4 - 7, 2013:
A great 4th of July weekend in Emeral Bay with the Corsairs! Motored over with no wind in about 3hr 20min. The drive train worked very nicely and the repaired hour meter ran the whole trip nicely.The water temperature is in the low 70s in Emerald Bay which made for a wonderful weekend. Ran the generator 1.5 - 2 hours/day which was more than enough to keep the fridge and freezer cold, mostly determined by the need for hot water for showers and the like. On the afternooon of the 6th about 20 people showed up for afternoon tea aboard Botany Bay. The big dinner in the cove was wonderful. The return sail was very nice in the late afternoon! We were able to sail all but the last 3 miles in about 3 hours and then motored the last bit back into the slip without incident for a wonderful weekend. About an hour and a half to get the boat cleaned up after in the slip.

June 24, 2013:
Washed decks small remote keyboard not working, probably needs new batteries.

June 23, 2013: Engine on 1045am not much wind engine, gen, transmission oil all look good. Away from mooring at 11am with a gurgling noise from stbd drain in cockpit while motoring at speed. Can see large air bubbles going by  in the cooling water from the exit of the oil heat exchanger to the vented loop.

Back in slip 1600 hours and trying to determine what the problem is with the engine cooling system: Started generator, engine,fridge while watching strainer basket. A big pile of seaweek of various types came into the strainer and the flow rate immediately increased significantly. The noise from the antisiphon went away. I pulled the strainer apart, cleaned carefully and re-assembled with lanocote on the seal and screws. Flow rate now back to normal.

There is no air at all in the clear line going up to the vented loop and back down to the water injection point. Looks like air was probably being pulled from either the fridge or air conditioning circuits which were both open.

Transmission fluid sampled and changed (7/8 quart, about 1/4 inch above scribe)

Main engine oil sampled and changed (3 gallons). Don't have a main engine oil filter, order Monday

Generator oil changed and oil filter changed (Westerbeke 36918 oil filter)

Note that 80% load is 21.6 amps at 50hz/220V out of generator oil filters also now. note: large water pump pliers are able to get a bite on the generator filter and remove if an appropriate sized oil filter wrench is not available.

June 22, 2013: 
Today is the Corsair Yacht Club Ashbridge race for 2013 which I got talked into sailing. Unfortunately there is not much wind out there today!

Ran generator this morning for 90 min. End time 3187.5 hrs, the generator hour meter is definitely not working properly.

Ashbridge start for us 13:32:10, however, we ended with DNF, not enough wind, got something around the prop/rudder and came into wind hole.  Almost made the point north of the cove and then could not. Tried running up the coast as the racers suggest after motoring around the point. 

Black plastic ring found on stbd deck after race. need to inspect hardware.

No steam/smoke from the diesel.

A good race! All fingers and toes still attached to crew.

Interesting observation, the time in the raytech "nuymbers" display is not seatalk time, rather it is the time on the local computer!!

June 21, 2013: Getting ready to head over to Catalina with Emily, Adam, Kim & Mike aboard for the Ashbridge Race with Corsair Yacht Club. Filled water tank for trip over with crew of 5 for the weekend, spot checked battery bank water level - about half way between plates and full marks. All batteries good but will need water before sweden. Looking in the bilge I can see that the joint between two water tank valves leaks slightly. Could see the damp area under at the bottom of the bilge, touched around and found moisture at the bottom of the "T" fitting between the tanks. May just need tightened a bit. 

1500 Oil checked, all good, warming up diesel, cleared harbor 1530, motor sailing for R10PV. Wind was good enough to sail from PV point to Isthmus! On mooring at 1900. At shutdown on the mooring a very slight amount of steam, may be just temps and the like but need to check it out.

True wind speed was about 10knts and the sailing performance numbers from hard on the wind to close reach look pretty accurate. Odd SeaTalk behavior on ocean temp, was cycling through three numbers, one of which was the correct value.

June 20, 2013:
I think I have a plan for the power system and got updated pricing on Victron inverters / isolation transformers from Jamestown Distributors:
3600 watt manual iso transformer $939.12
3600 watt auto iso transformer $1385.45
8kva 230v $5752
5kva 230v $4344
3kva 230v $2826
100amp 24v TG charger $2124
100amp 24v Skella I charger $1989.12

June 19, 2013: Testing the generator hour meter. Running microwave on generator 3186.0hrs start (15 hours on gen oil) 30 min of run tonight. finished 3182.2 Might actually be running slow. Definitely need to replace the generator hour meter.

June 19, 2013:
Installed bulkhead connector in the aft shower to stop water from getting under the seat when taking a shower. West marine part number 5358254 made by ambassador marine part number 131 0015 CP "Elboe Bulkhead Shower Head". 

With only a small amount of sanding on the supports under the seat I was able to install the connector and re-arrange the whale plumbing system to match the new configuration. I have been able to make significant modifications to the system in terms of taking things apart and putting them back together in a different configuration without any leaks showing up. A very nice plumbing system, highly recommended. The existing hardware is a 20 year old style with 15mm plastic hard line, o-rings, and metal keepers. The modern version is easier to work with and uses the same diameter tubing (either 15mm or 22mm).

No more water showing up under the seat after taking a shower!!!

June 17, 2013: Replaced LPG gas sensor under stove which has taken to going off in the middle of the night. West marine part number 9457367 which is trident part number 1300-7720.

This one started acting up with false alarms about a year ago (3 years old) and has gotten worse over time. The propane sensor/control is on the same circuit as the rest of the galley and so is on almost all of the time. (Not the propane itself, just the control panel and the sensor). I like having the sensor online so if these have a limited life it just becomes a consumable. It will be interesting to see how long this sensor lasts.It is described as a "Marine L.P. Gas Detector, 12 or 24 VDC, UL listed, Alarms & sends shut off signal to gas control panel when L.P. gas is detected, Part # 1300-7720"

On LBB I had a similar problem but after a longer period of time as it was on a seperate circuit and thus was not running all of the time.

June 16, 2013: General boat cleanup, all linins and blankets washed; decks washed; removed epoxy supplies from the lazerett

June 6, 2013: Spent most of the day considering the ac power system. I did verify that the air conditioning system works from 208V - 230V 60hz and nominal 200V at 50hz.

It should pull 6.25A at 230V in air conditioning and 7.5A in heat. So both running full out should consume about 15A. Which is right at what the Victron auto-selecting isolation transformer can handle.

Still unclear if the microwave would like 60hz 230v power. It does run but produces little heat on 60hz 208V. There are some interesting comments online about microwave ovens on the wrong frequency. Apparently each pulse of the magnatron comes twice per cycle. Thus a 50hz microwave on 60hz power outputs about 120% of design power but will eventually fail. A 60hz microwave running on 50hz will output about 83% of planned power but the transformer if designed closely for 60hz will fail. The internal difference between the two units is the size of the capacitor which is charged twice a cycle and is selected to get the right power level for a given voltage and frequency of power.

Removed old supports for small autotransformer installed behind the nav seat.

Size of cutout for inverter / battery charger control is 3" x 6" approx. Overall is 4" by 7"  could grow to 4" by 9" if willing to cut teak. Power selector under nav seat is about 6" by 6" overall. Above power panel is 1.75 high by 5.25 wide

June 1, 2013General repair work. Tom and I pulled the hour meter, I was able to roll it forward by pushing on the lowest digit slightly while the meter was running. Now at 1000.0, connected meter directly to the battery and running meter forward based on the following:   - Meter ran 1.6 (998.4 - 999.9) hours
before stopping on way to catalina.
  - Ran engine 3 hrs 45 min on way over, 3 hrs 20 min on way back, sailed for awhile and then 35 minutes. result is about 7.6 hours - 1.6 hours or 1006.0 is approximately the correct value for the hour meter.
Stopped running engine hour meter forward  at 1006.1 hrs

Rebedded the dodger aft and top mounts.

Note: hour meter cover is glass, glued bezel back on with something called "plastic surgery" which looks like it worked. Just a few drops around the edge of the bezel to hold it on.

Engine hour meter repair with plastic glue looks well setup after an hour, reinstalled and ran engine to verify all meters working (tried checking all of the connections on the tach, still no op.)

Currently about 40 hours on the engine oil, Transmission oil changed at 993.6 = 12.5 hours on ATF. Plan to change engine & transmission oil at 50 hours or about 10 hours away.

May 27, 2013 Heading home after a nice weekend over in Emerald Bay. Started engine at 1000, note that hour meter is still stuck. No wind at this point. There is perhaps 16.75 inches of fuel, boat is rocking on mooring will need to check in King Harbor. Dropping mooring at 1010 hrs heading for R10 from Emerald Bay.

Motored until just off Redondo bouy and decided that the wind was too nice up and down the beach and decided to sail up to the refinery ships and back. Motor down at 1320 hrs, sailed until 1455 hrs, then into harbor and motor off at 1530 hrs.

Fuel meter reading 11 inches of fuel, I suspect that the rolling around of the boat has the fuel measurement tube bent again...

Opened fuel tank access and pushed plastic tube back into place, it is somewhat bent and so may not be reading the full depth. At this point it is reading 15.5 inches of fuel. This would be about 1.5 inches of fuel less than the start of the trip, motoring both ways making about 6.5 knts without the sails outbound (8.1 with the sails later in the trip at same throttle setting) and 7.1 knts on the return. About three hours of run each way (not including the sailing time and wandering around harbors so call it 7 hours of run time (6 plus about an hour) and consumed about 15 gallons of fuel. With a couple of hours of generator time that would be about 2 gallons per hour of fuel consumption, both directions had significant chop and very little wind or wind on the nose.

Will check the fuel level in the morning when the tube may have returned to it's normal shape. May be worth replacing the tube with a new one which would be stiffer and perhaps reach the bottom of the tank better.

Additionally, tried to take pictures of some strainers on the ends of the pickup tubes for both the generator and the main engine. Need to talk with Oyster about these and if that is a good idea in the current concept of large filters and recirculation. Definitely need to consider the fuel system as we rebuild.

No antifreeze under the forward part of the engine, looks like tightening the clamps on the circulating pump hose stopped that seep. Plan to replace hose and possibly rebuild the pump in the fall.

Looks like the knotmeter is running about 5% low (i.e. measures 7.0 knts, real number is probably 7.35knts) Will work with Tom in the next week or so to get the calibration right.

Stuffing box is good, only a slight amount of moisture under it. Cleaned up the stainless donut for good measure.

Some moisture came from under the fridge near the battery box blower fan. About half a paper towel worth.

No moisture under forward v-berth, I suspect the moisture was from the slightly leaking hatch above the berth when there are boarding seas.

Transmission shift leaver weap appears to be getting less over time. Probably one drop over 7 hours of engine run time.

One instance on the first day of the nav system getting a position off near or at 0N 0E. This can cause significant issues in the cross track error and may require at minimum resetting the cross track, re-selecting the waypoint, or restarting the nav software. Not clear what is the minimum required.

Definitely appears that it is necessary to bring up the autopilot (and thus the seatalk bus) prior to turning on the VHF/GPS circuit.

About half the time bringing up the Raytech softward I can't select a waypoint and have it stick, bringing down the raytech software and starting it up again appears to clear the issue consistently. It is worth noting that this configuration is not supported my Raymarine explicitly and they are surprised it works at all. They would rather have the autopilot and the instruments on seperate busses into a chart plotter to ensure these issues do not crop up.Probably time to consider cleaning up the seatalk bus completely. The wiring is a bit of a hodge podge and could use a careful looking after.

Tried sailing to a wind angle again, won't do it successfully and the wireless remote is not getting a vane angle report from the pilot. Being that it is able to successfully talk to the pilot I suspect that the wind point information is not getting to the pilot succesfully. Definitely a feature I need to get working correctly. Another potential artifact of this non-standard configuration.

Marked the port sheets and the mainsheet/outhaul for 45-50 degrees apparent, was seeing 100% of the expected performance in 14 - 16 knts of wind. Definitely need to start marking things to get to repeatable configurations.

Saw 23 amps out of the alternator with the batteries down 55 ah. Looks like tightening the belt did improve things significantly.

The walls of the fuel tank look pretty good, however, the bottom looks like it could use a good wipe down as there is some dark material on the bottom of the tank. Should probably change the fuel filters for both the generator and engine (especially the engine) after that much sloshing around of fuel.

May 26, 2013: nice party aboard with about 40 people, ran generator for about an hour, ending hour meter 3184.9

May 24, 2013: Heading to Emerald Bay for Memorial Day weekend with the Corsair Yacht Club! 1615 starting up engine heading for emerald bay; underway 1640; motoring to weather at 6.5 knts. tws is 8 knts; hoping for a good angle to emerald. course is near pv north rather than R10

Interesting, knot meter is intermittent, tried recycling the bus but no impact on intermittency. appears to be a sensitivity issue as itworks better when there is more wave action. Will take a look at the face when we get to emerald.

Engine hour meter is stuck at 0999.9!!!

Motor sailing at same throttle setting which makes 6.5 knts, making 8.0 knts in 7knts true at 90 degrees true. Motor sailed all the way, at enterance at 1940! Three hour run

Engine off at 1955, hour meter still dead. 17 inches of fuel at shutdown.

Two Oysters in Emerald Bay

Two Oysters in Emerald Bay, "Botany Bay" a 1990 Oyster 55 and  "Sea Avenue" a 2010 Oyster 56

Botany Bay In Emerald Bay

The varnish on the Saloon Sole is now in very nice condition. I just need to finish the rest of the boat!

It takes quite a few cans of varnish to do the Saloon Sole, 11 Quarts just for the Saloon!!!

The new forward shower sump manifold and drain are working very nicely this is the Whale Greywater IC system ( WM8484 )

The new Treadmaster SP looks absolutely beautiful!

The new Aqua Signal 34 Series Running Lights in white plastic look beautiful!
Re-Stepping the Spar
Botany Bay gets a Christmas Present! The mast went back in on December 23rd, 2010. I had been unable to get back to LA to get the rig in earlier although SeaTek was ready several weeks earlier.
