I spent along time looking for the most boat I could buy.
I tried very hard to find a used Beneteau 50 to purchase, but they either were
$300 grand or a stripped down 4 cabin version used by the Moorings. I feel
I got the biggest boat that I could afford and still have enough money left over
to install the things I thought I needed. Short of finding more money, I
would buy the same boat again.

Existing Equipment on the boat:
- Primary anchor, 45 lb. CQR
- Second anchor, Fortress
Things I purchased or added to the boat:
- Raymarine E80 Chartplotter
- Raymarine 4kw radar antenna
- Added a halogen light on the mast for a deck light,
doing it again I would have a total of three halogen lights.
- Upgraded "steaming light". 30 watts bright I
believe.
- Northern Lights 8kw generator, with control panel for
nav station. This unit is great but I might look into getting a
Westerbeke genset which is what my motor is. Then I might be able to
use the same filters, spares etc.
- Standard Horizon VHF/Hailer, w/ side speaker.
Hailer has been very helpful. Fog horn has been helpful.
-
External Speaker for hailer on mast.
- 30 gal fuel tank added, for a total of 80+ gallons.
Very nice.
- Spectra Newport 400 water maker, with control panel for nav
station. I don't see how you could do it with out, but many people do.
The unit makes 17 gallons per hour.
Icom SSB and tuner. I do not have the paccar (?) modem for email, that
would be nice but not necessary
- Raymarine E80 chart plotter. Mounted at helm,
requires about a 3" height adjustment in helm.
- Raymarine fish finder (have not gotten this to work
yet)

- Raymarine 8001 (?) autohelm controls and computer
(forgot the name of model # of this)
- Life raft. I purchased the soft case, big
mistake, should have gotten the hardtop mounted on deck.
- Have a total of two propane tanks, need both of them.
One will last about 30 days.
- Screw on water filter for sink.
- 5 battery banks. One in bilge, one in lazerete,
and two under bed, and fifth for the engine. The engine starter
battery has crapped out on me twice. It is a traditional auto battery
for deep cranking but I think it charges at a different rate than the rest
of them so it burns out. I will replace it with one like the others.
- 280' of chain. This has been very helpful in
the deep anchorages of the North West. I think it will also be useful
in the Caribbean, because the coral heads can cut right through the rope.
I have no rope, just the chain. The weight of the chain helps balance
the weight of the genset. My anchor/chain has never dragged, this
helps you sleep when the wind is blowing.
- Modified both heads so that with a Y valve, I can
dump waste directly over, helpful when underway.
- Added a tri-nav light/all around/strobe on top of the
mast, with a switch for the strobe mounted on the helm.
- Replaced 3 db whip VHF antenna and upgraded the VHF coax cable with a thicker gauge.
(can not remember now the gauge thickness, but it is thick). This was
easily done with the mast out of the vessel.

What is the transmission line loss for coax?
This depends on the amount, as well as the type of coax used. On the average, 50
feet of RG-58 coax will have about 3dB loss, 50 feet of RG-8X coax will have
about 2dB loss, and 50 feet of RG-213 (RG-8U) will have about 1dB loss.
Calculation for Range of an Antenna:
Square Root of Height (in feet) above water x 1.42 = Range in miles
Remember to perform the calculation for BOTH vessels, and then add
the results for the range between two vessels. |

- Flat screen monitor with DVD player (very nice !!!)
- Two A/C //heater units, boat needs three.
- CD player
- Large custom davit for a 10' RIB dingy and 10 hp
motor (should have gotten 15 hp motor)
- Very nice touch of adding two red trailer lights on
bimini frame pointing down. This allows me to have some red light at
night when I need it while adjusting lines or what ever. Very cheap to
do, but a big help.

- Electric winch (very nice)
- Jack Lines
- Inflatable PFDs
- Iridium Sat Phone
- GPS EPIRB
- Two radar reflectors

- TrackVision 4 - Direct TV satellite receiver

Things I would like to purchase:
- Do not have a wisker pole, this would be nice to have
but I get along with out it.
- Do not have spinnaker, but I'm fine with using the
engine in light wind. I generally want to get to where ever I'm
headed.
- Would like an alternator regulator that is aware of
the battery state and can vary its output.
- Possibly would look into adding a second Racor fuel
filter unit, either installed in serial or parallel with a Y valve.
- Possibly would look into options for upgrading or
helping the frig & freezer. I at least need more insulation.
- Would like to look into (not sure their brand name)
the prop cutters which cut through any line/sea weed that gets caught around
your shaft. This has been a problem. This problem has lead me to
believe I need a small scuba tank onboard so that I can check the bottom of
the boat or untangle something while at sea. I tried doing this with
mask/fins, no way could it be done in only a 1 knot current

Things I don't think I need:
- As I said, I do not have any light air or storm
sails. Neither has been a problem.
- Don't see how I would use a solar panel or wind
generator. The diesel genset with the extra batteries does it all.
- I do not use safety netting, don't believe it would
help.
- I have lots of guide books but no paper charts.
The Raymarine E80 is what saves my day every time.

Advice from others who have a MaxProp:
"My 461 has a 3 blade 19" MaxProp.
I have the Westerbeke 63C engine. My calculations and PYI's calcualtions
matched at a 20 degree pitch for the propeller. This is also the pitch
used with success by 461 boats with
the slightly larger Yanmar engine, so it seemed to be a reasonable
starting point. My experience found that it was too steep, the
engine could not reach maximum RPM. At haulout I will be decreasing the
pitch to the next setting."
