Main Message Board / Raymarine Wind Indicator bracket screw specs
« on: May 05, 2014, 10:09:04 AM »
Hi All,
Does anyone know the screw size (length, thread, etc.) of the two screws that hold the Raymarine Wind Indicator bracket to the top of the mast?  See attached picture of the two screws in question.


Main Message Board / Broken Alternator bracket M35B
« on: April 22, 2014, 07:12:53 AM »
Hi all,
Wanted to see if anyone has found this to happen on their M35B engine.  Attached is a picture of the alternator bracket. When I was checking things over to prepare for spring launch, I noticed the alternator to wobble and upon further inspection, found the bracket to be cracked.  Called Joe at Westerbeke and he said he may have seen this once or twice since the introduction of the M35B in the late 90's.  I have a 100 amp alternator, so he feels that might be the reason for the break.  However, I know many have upgraded alternators, so that reason may not be all that true.  Based on the dust I see in the areas that are broken, I was probably running the engine with this cracked bracket, since the broken areas are not shiney from a recent brake.

any thoughts?


Main Message Board / V-Berth drawer converted to cabinet shelf
« on: September 26, 2013, 01:05:37 PM »
Hello everyone,
Iíve never used the center drawer in the v-berth because we keep the cushion insert in the up position.  With that insert above the drawer, you canít get to the contents, because the insert blocks the opened drawer.  What I did was convert the drawer to a stationary cabinet shelf with a door.  I took the facing of the drawer and added two hinges at the bottom.  That now has become the door.  I created the enclosed cabinetry by creating a box using the sides and back of the drawer (sides cut down to length) and plywood top and bottom.  This box is attached to the lip on the frame around the drawer that screws into the fiberglass.  I didnít go too deep with the cabinet, since I didnít want to impede access to the depth and speed transducers right below.  This was a relatively simple transformation and makes usable storage space which was previously not accessible.  I painted the inside with off-white interior trim gloss paint that matches the interior fiberglass pretty well.  The finished product looks like it was OEM!

Main Message Board / Top Down Asymetrical Spinnaker furler
« on: July 24, 2013, 04:34:36 AM »
Hi all...
Has anyone bought one of those top down furlers for their spinnaker?  How do you like it?  There are many out there (Karver, Selden, Profurl Spinex, etc, etc....) which did you buy and why.
Doing some fact finding and thinking about getting one.

Thanks  :D

Main Message Board / Rust in Air Conditioning pan
« on: May 06, 2013, 10:09:54 AM »
Hi all,
I have a Marine Air unit and it works fine.  It's about 11 years old.  I noticed the bottom of the pan is getting rusty.  It's not large pieces of rust scale that are falling off, but a reddish tan "blush".  When you rub your finger along the bottom, the rust dust is on your finger.  Here's my question...  I have a Mermaid Condensator that sucks out the condensate from the pan.  At the tail end of last season, I noticed the hose and fine mesh filter was full of this rust particulate.  The particles are very fine and make their way past the filter and into the hose beyond and into the condensator.  This is the filter and screen that is advised by Mermaid for their Condensator unit.  My thought is if there was something I could pour into the pan that could solidify on the bottom to contain the rust and keep it away from the water.  Maybe some kind of liquid plastic, epoxy or something that is self leveling.  I don't want to do anything elaborate, but something easy to keep this thing running until it just breaks down.  I really don't want to get into a project of replacing the pan on a unit that old.

I wondered if anyone had some ideas or a similar situation that can offer advice. 

Main Message Board / Blue Sea Systems digital voltmeter
« on: October 09, 2012, 04:24:13 AM »
I installed a digital voltmeter on the panel.  When it's not sensing any voltage, the meter reads .03 volts.  Called Blue Sea Systems tech service, but they couldn't give me a good answer why.  Interesting to note, saw some boats at the boat show with the same unit, and those meters were also reading .03 volts.  What is the electrical explanation for this?  Also, I'm thinking if I want to know the true voltage of the battery, I would have to subract this factor out?  I would figure the meter should read 00 when no voltage is being metered.....

Main Message Board / Golf Cart batts re-positioning & wiring diagrams
« on: September 26, 2012, 05:11:04 AM »
I've used 4 golf cart batteries as my house bank for the past few years with much success.  I just had a thought that maybe it would be a good idea to rearrange them so the current flow doesn't remain the same.  Kind of like rotating the tires on your car for even wear.  My thought is if current flows through the batteries in the same pattern time after time, the battery in a certain position would degrade at a different rate than the others.  Maybe moving them around will "exercise" them and keep them at full potential.  Any EE's out there with any thoughts if this really matters would be helpful  :clap

Main Message Board / No nuts on Stern Rail bolts
« on: July 08, 2012, 12:34:09 PM »
Hi all...
I happened to notice that there are NO Nuts on the bolts that attach the stern rail to the transom.  At every verticle rail attachment point, there are bolts that come through the fiberglass, only protrude through about 1/4", and there are no nuts with lock washers attached.  The bolts used aren't even long enough to have bolts and washers on them in the first place.  Can those of you with MkII's look into the aft lazarettes and see if yours are like that too.  I plan on calling Catalina to see if this was on purpose, or did someone forget to finish the stern rail installation job when the boat was built.  I have no leaks....which is good...wish I noticed this when I bought the boat so the dealer would have fixed this.  Curious if other boats are like this too. May have been a widespread production hull is 1477.

Main Message Board / Tack Line into cockpit
« on: May 17, 2012, 04:57:01 AM »
Hi everyone,
I'm looking for ways on how to secure the Asym. Spinnaker tack line in the cockpit.  I plan to have the sheetblocks attached to the stern cleats.  So leading the tack line back to one of those might end up having too much on either one of those cleats.  My thought is I can run the line outside the stanchions and around the midship cleat that I have on the outer track.  That might help the tack line lead back into the cockpit.  However once in the cockpit, I'm trying to think how best to secure it.  Any ideas would be appreciated.

Main Message Board / Spinnaker sheet blocks
« on: March 26, 2012, 05:19:09 AM »
In the latest Mainsheet tech section, I saw some pictures of spinnaker blocks mounted on the stern cleats.  What caught my eye was the fact that these had beckets with a bungee line attached running to the stern rail, thus suspending the block up.  I'm in the process of getting some Garhauer sheet blocks and don't know if I should get the ones with a becket or not for suspending the lazy block with a bungee cord so it doesn't flop around when the sheet is slack. Has anyone found a floppy block to be a problem?  The other option is just to run a bungee cord through the center hole in the block (without the becket), but not sure if the cord would have chafe from the turning block when the sheet is used.

Would be interested to hear what others have done with spinnaker sheet blocks.  Pictures please, if available.

Main Message Board / Holding Tank odor control products
« on: March 06, 2012, 04:05:25 AM »
Message for Peggie....In the recent Practical Sailor, two individuals wrote in about some products they use and would like PS to evaluate.  One is called BacTankT3 and the other is called Happy Campers (this one advertised as an RV product).  Do you have any experience with these two products?


Main Message Board / mooring balls on back creek?
« on: February 28, 2012, 06:11:23 PM »
Does anyone know if there are mooring balls on Back Creek in Eastport?  Looking at putting my daughter in Kidship Sailing this summer and wanted to moor on back creek for a few days while she takes lessons.


Main Message Board / UK Sails - Annapolis
« on: February 01, 2012, 04:54:27 PM »
Has anyone purchased a sail from UK Sails in Annapolis (Eastport)?  Thinking about an Asym from them and would like to know if anyone had any good or bad experiences.  We visited the loft last weekend and they seem very knowledgeable and have a nice set up.


Main Message Board / Asym Spinnaker mast head modifications
« on: November 07, 2011, 01:18:33 PM »
Hi All,
I'm interested in getting an Asym Spinnaker and have been gathering information.  Went to local sail loft and talked about what was needed at the mast head.  I was told that the extra halyard on my mast (does anyone has a picture of the top of the mast to confirm) is really a spare jib halyard and not a spinnaker halyard, because it's not outside the foretriangle, above the headstay.  What I was told is I need to cut into the mast, about 3-5 feet down from the top and install an exit plate.  Run this halyard through it and up through a block on the bail (again, not really sure I have a bail up there).  This will place it above the existing jib halyard, above the headstay.  The loft said don't let anyone tell you to just run it up from the sheeve to a block on the bail because things can get messy up there if you do.

Also, is using a sock really helpful, or are they overrated?  The ATN sock is not that cheap and I'm researching that cost compared to those small furlers, wondering if a furler is worth the upcharge.  My local loft says a sock is good enough and is talking me out of a furler.

Any info would be appreciated.


Main Message Board / ST60 Wind Vane binding
« on: October 11, 2011, 01:15:51 PM »
Hi all..
This is something that has progressively become worse over the years.  Here's the situation.  At times, in light air, I can be sailing close hauled with wind definitely apparent on my face, but the wind vane ontop of the mast would stop spinning.  Then it would start up again.  Went up the mast this past weekend and pulled it off.  I can't notice any binding when you try to spin it by hand.  The cups do wobble a bit and move in and out, but I can't feel any hard spot that might hang up.

Before I send it to Raymarine, would like to know if anyone has any insight with this situation.
