I moved the compressors (fridge & freezer) out from underneath the freezer box on my OC45. c/o CSR Marine, Seattle WA. Getting the freezer box insulated also. It had zero insulation, gads! The new location for the compressors is behind the port moving seats. There is a huge void of space where the heat from the compressors can move. Will also put vents in the new access panels. I will update on reduction of amp load once this is all complete.

-Simrad electronics can be troublesome, as is there support. My radar has never functioned reliably. This alone might give me pause in purchasing another Beneteau.
-Have the main shore power GFIC Breaker replaced with a conventional breaker if not already.
-The arch is prone to all sorts of cosmetic stress cracking, also mine is leaking into the starboard aft cabin.
-Never overfill the sail drive. It will end up blowing past the front seal.
-Upgrade the factory 80a Hitachi Alternator. It is woefully inadequate.
-The Freezer option is a crowded affair and results in poor ventilation for both the refrigerator and freezer. I'm considering mods.
-Consider other options for the problematic AC condensate pumps
-The Dometic QLogic interfaces are prone to separating from the facia. I glued mine in lu of the clips.
-The raw water supply to the generator is at some distance from seacock to pump, causing frequent impeller failures. The strainer should be relocated as it is impossible to service. Keep spare impellers on hand and learn how to service it. Also the coolant reservoir interferes with removal of the generators inner accessory shield. The impeller is a Sherwood 8000. 1/3 the price of Onan/Cummins.
-The battery voltage on the display panel is inaccurate (0.3~0.4v low) causing a premature alarm, but I think this is the case with all Benny's.
-the Main sail furling unit should have roll pins holding the end housings in place and not keeper bolts. Keep an eye on it, making sure they are tight. US Spar was very good about taking care of mine after it spilled its guts on the deck. The updated units are pinned.
-Inspect the Head sail furling unit to the sail luff drum extrusion. My terminology here is weak but I hope you get the gist.
-I truly wish Beneteau would install some basic supply wiring for cabin fans. It's mentioned in the literature but I have struggled to find evidence. This seems so rudimentary to me.
-Both seacocks for my Sailvacs were leaking around their elbow assembly threads. Their manufacturer uses a hard glue that would seem incompatible. Once installed in the boat it appeared they were adjusted with a pipe wrench by the factory, cracking the glue and resulting in waste seeping into the bilge. I removed them, cleaned the threads and applied a different thread sealant.
-Keep a rebuild kit on hand for the Sailvac vacuum generators. The check valves can fail.
-I can go on and on about the Sailvac. I've learned to keep them working and as such can realize the benefits of their very stingy water usage, but it has not been without effort. I can always get them to flush, but it sometimes requires resorting to manually turning on and off.
-I'm a huge fan of Micron CF on the Chesapeake, and a few days spent in fresh water mid season, even if it happens to be the nasty waters of the upper Delaware.

I've installed a couple of unnecessary extravagances that may have questionable merit for the cruiser, a fuel flow meter and a Flexofold prop. The fuel flow meter is nice but all it proved was that the Yanmar performance chart was actually fairly accurate in fuel consumption. I do like the fuel totalizer though, and seeing realtime fuel burn does motivate me to back off. Some may argue for the folding prop but it's hard to find good evidence that it provides a noticeable improvement relative to the expense for a weekend cruiser. It also hinders performance astern.

Indeed the boat is easy to sail. I started single handing almost immediately, and even when I have crew I'm usually single handed anyways. ;-) I do appreciate the help though when flying the spinnaker. I've thought about adding a remote to the electric winch on the cabin top. This would allow me to control the Haylard from forward.
Hi Missingyou

You mention fuel usage

Please could you let me have your fuel consumption for 2200rpm and 2500rpm

regards

Well, tell that to the unlimited tonnage ships masters (many whom I know personally) who wake up an hour or so before his officers watch change and just before nautical twilight where said Captain turns off the screens and orders his officers to shoot the stars. Said Captain tells his junior officers he expects them to have results calculated to be within 5 NM of the actual GPS position of the ship. I suppose a ship with all its multimillion dollar navigation equipment and highly trained crew is no match for a weekend warrior navigator.

Furthermore the USCG has issued several Notice to Mariners stating: 1) Expect GPS satellite coverage to be out for periods of time because the replacement rates for new satellites have decreased; and 2) There have been attacks on the satellite software that have temporarily shut down the satellites.

Having a working chart plotter that does not receive a signal because it is not being sent a signal while in the middle of the ocean would be somewhat of a problem if one does not know Cel Nav-- don't you think? Said weekend warrior fires off his electronic (not necessarily EPIRB) SOS triggering device or gets a location by calling on Satellite phone. Then the ship Captain as stated above has to reroute his ship to save some weekend warriors ass because they were too stupid or too arrogant to not learn how to properly navigate--Costing said Captain to expend time, fuel, and money.

I might add that all USCG licensed deck officers with an ALL OCEANS endorsement only received that endorsement after qualifying and passing their Cel Nav Exams and earning said endorsement.


Maybe I am biased as I am a Licensed Master.

The OP seemed to be configuring a cruise ship apartment, more than a circumnavigator. I say, have all the creature comforts one wants. However, a 26" TV is a must, but no water maker? Passes on a diesel generator, but also no mention of solar or wind gens. Then there were concerns about being able to dock and possibly adding a rubber barrier to prevent damage. The final straw was the thought of having a life raft was qualified with "maybe".

It was a couple of years ago, I wonder how they made out.

MarkofSeaLife By the way, for the unsafe idiots who wish to navigate by the stars you can do so with an app on your smart phone.

Just point the smartphone at a few stars and it gives you lat and lon.

Like this one. http://appcrawlr.com/android/starstruck-navigation

*** For celestial navigators: a Smartphone is a small box that looks like a small box with a small window that when electricity is applied via the On button appears like a cathode ray tube. Things wriggle on it. You add a small bit of plastic from a company called a 'telephone company' and you can ring Mum just like the 2 tin cans connected with string you currently use.

First, paper charts should be your primary navigation tool, not chart plotters. Second, make sure you know how to perform Celestial Navigation. Third are you sure you want to go around the world in a Beneteau 45? The boat is not designed for that type of sailing. Yeah you could easily sail from the US to the Caribbean, but crossing the Atlantic, Pacific or Indian oceans are way different sets of conditions.

Good Luck!
