Main Message Board / Battery Equalization question
« on: July 20, 2020, 12:35:13 PM »
Hi all,
Thought an electrical savy person can have a reason for this situation.  I have 6 volt golf cart batteries that I started equalizing last weekend.  I have a Truecharge 40+ charger.  Here's the situation.....  I isolated the bank to be equalized by putting my selector switch to the reserve battery.  So my systems were powered by the reserve battery and the bank to be equalized was off the grid.  I triggered the equalization process on the charger.  All seemed like it was going fine.  I washed my hands, and the water pump went on.  When the pump cycled, I noticed the volt meter reading (set to read the bank that was being equalized) dipped down a few tenths of a volt.  As soon as I turned the water off and the pump stopped, the volt meter returned to the display it was before the pump cycled.  I switched the volt meter to read the reserve battery.  I turned on the water and noticed the volt meter reading to significantly change, which made sense since that battery was taking the load based on the selector switch position.  I can't figure out why the volt meter moved when it was reading the bank being equalized when the pump cycled.  Intuitively, that bank should not have any load since my selector switch was set for the other battery.  I checked the connections on the battery switch and it all seemed correct.  Any idea of why the meter moved a few tenths of a volt?

Main Message Board / Winterization anit-freeze for two winters
« on: November 15, 2019, 12:36:33 PM »
Hi everyone,
This past season we didn't put Sea Life in the water.  With other plans over the summer, we decided to take a hiatus.  Everything was winterized for last winter and over the summer, we did not do or change anything to the systems.  I'm thinking since everything has been untouched, we can go through another winter.  Any thoughts if I'm missing something?

Main Message Board / Inflatable repair in Annapolis
« on: October 01, 2016, 05:45:31 AM »
Hi everyone.
The rub rail on my inflatable dinghy has come off. Probably due to the glue being dried out. The dinghy is in great shape otherwise. The 2 part glue and primers needed is not cheap, along with the amount needed to do the job.  I was thinking of just having a repair shop do it. I know there are places on Annapolis.  Anyone know of a place with good service?


Main Message Board / Mast fair leads
« on: September 07, 2016, 11:31:23 AM »
Just curious, but what do most use these two fair leads at the base of the mast for?  I haven't used them for anything, but wondering if they could make something better......

Main Message Board / Battery Terminal corrosion/why after many years
« on: July 05, 2016, 04:02:46 AM »
Rather than add to the existing topic which is about prevention (which I copied the link below), here is a new thread about what I'm seeing on the terminals.,7201.0.html

I've had 6 volt golf cart batteries since 2009 and they've been working great, and still do.  For the first time, last year I noticed white powder (corrosion) on the negative terminal.  I cleaned it with a water/baking soda paste, wiped everything off and assembled together.  This season, I've noticed the same thing (not as much as last year).  Up until now, the terminals have been spotless.   I see that this is usually the result of improper charging.  I have a Truecharge 40 (at least 10-12 years old model, not the newer model, but original Truecharge design), and it seems to be working same as usual.  I have a digital volt meter and I can see the charging sequence looks correct.  I have the settings at "Flooded" and "Charge/bulk/absorption".  I have a temperature gauge, so the temp setting is not used.  I also notice green corrosion on the positive terminal, right where the shrink tubing ends, but not on the terminal itself. 

I do realize, the terminals are not "tinned" as Mainesail suggests, however up until recently, they have stayed clean.  When I cleaned the terminals last year, I did rub some Super Lube on them, but maybe I didn't put enough?

Pictured is the negative post.  You can see white powder.  The other negative post has the temp gauge, which the terminal appears to be very clean.  The last picture is the positive post and you can see green corrosion near the shrink tubing.

Interested in any feedback on this.

Main Message Board / Shrink and Insulated terminals
« on: June 21, 2016, 05:00:04 PM »
Hi All,
I purchased the Pro HST crimp tool from Mainesail's site.  Real nice quality product.  It's pricey, but it looks like you can just about make a fool-proof crimp.  I like the nice wide jaws.  I have various terminals, and they all seem to be the insulated type (I'm throwing away all the cheap ones after reading Mainesail's how-to info).  I'm wondering if these insulated terminals really won't work with this tool.  In the past, I've used these terminals with adhesive lined shrink tubing to make a water-tight seal.  I don't have all too much of these various terminals, but if they won't work, it's a shame to throw them all away and get the shrink sleeve terminals.

Saw this picture in Cruising Compass....  Hey, is this the same Mike Stimmler on this site?  If so, how did you snap it....hanging over the edge of an aircraft carrier?

Main Message Board / Won Mantus Anchor (well sort of)
« on: December 22, 2015, 07:09:10 PM »
Hi all,
Not trying to open up a anchor discussion...  but I won a gift certificate from Mantus, but just short of enough to buy a 35b anchor. I would need to kick in $130 plus shipping to get an anchor worth $330.  I currently have a 35lb Delta but not really in the market for a new anchor. However, the Mantus is a new generation of anchor and the Delta is old technology.  I plan to look at PS to see what results they got on their anchor tests.  But just wanted to see if anyone here has had any experience with the Mantus and is it worth it.  I could use the certificate to buy a few smaller items that add up to $200 instead of buying one large item.

Main Message Board / Electronic charts for Chartplotters
« on: November 17, 2015, 04:49:29 AM »
Hi everyone,
I'm gathering information on chartplotters and the one thing I see that is so overwhelming, is the many different electronic charts available and what chartplotter uses what.  Here's a recent article from SAIL Magazine.  Not only do you need to search out what chartplotter to buy, but then you have to rummage through all the different electronic charts and see what chartplotter uses which software.  You can't buy a chartplotter, then choose whatever electronic chart to use.  You have to make a decision based on both the hardware, and the software it will support.  Many chartplotters have the ability to use multiple charts.  Garmin, on the other hand, seems to only support their own "blue chart g2".

Interested in getting dialogue on what's good and not so good with respect to chartplotters and the software they support.

Main Message Board / Salon speaker location options
« on: September 06, 2015, 01:31:53 PM »
I did a search and found the posts describe cockpit speaker location.  I'm looking to upgrade the stereo.  I currently have Poly Planar box speakers mounted on the bulkhead facing aft.  They don't have a great sound and was thinking that flush mounted speakers, mounted in a cabinet somewhere, would give better bass and better overall sound quality.  I understand that speakers need to be mounted in an enclosed cabinet to function properly, and I'm wondering were you folks have installed them to get some ideas.  I'm thinking about the the upper little cabinets, just forward of the port (ports below the rubrail) on both sides of the salon.  They would face directly aft.  In measuring the available teak to make the hole (I hate to drill into good wood!!), I wouldn't be able to fit a 6 1/2 diameter speaker, but would need a smaller diameter to fit.  Has anyone put a speaker in those cabinets and do they give good sound?  If anyone has pictures of their mount locations, that would help with some ideas.


Main Message Board / Stereo watts per channel
« on: May 19, 2015, 04:02:12 AM »
Hi everyone,
I installed my stereo 15 years ago (AM/FM/CD), and back then, the CD player was the thing to have.  Now... it would be nice to have bluetooth, USB, MP3, etc..  inputs, so I'm investigating some new stereos.  I have a question to the audiophiles out there.  The speakers I have in the cockpit (Polyplanar) are rated as 40 watts max.  The speakers I have in the cabin (also Polyplanar) are rated as 50 watts max.  The current stereo is 40 watts per channel. The stereos I'm looking at now are rated as 60 watts per channel.  Is there any issue with getting a stereo rated higher than the speakers it is driving?  I'm thinking no, because I believe the max watts output is when you have the volume blasting, which is unlikely the way we listen to our music.  Also, I'm looking at a Dual stereo at WM, and Defender is big on marketing Boss Audio products, since they seem to be showcasing most stereos by that company.   The Boss Audio stereos look iteresting and at a good price.   I'm in no rush, so I'm waiting for something to go on sale.  Any thoughts would be much appreciated.


Main Message Board / Catalina Plant on "How it's Made"
« on: January 20, 2015, 07:55:29 AM »
Hi all,
Yesterday my daughter and I were watching a show called How it's Made.  It's a show that has 3 or 4 different segments on how something is made.  Each segment only lasts several minutes during the 30 minute episode.  It's very interesting if nobody has seen it before......  Well, in yesterday's episode, one of the segments was called Luxury Sailboats.  It started out by showing how a rudder was made, the stainless steel stock and the expandable foam filler that creates the internal part.  It then showed the rudder mounted to the hull of a boat that was in production.  Then the camera showed how the reinforcement structure grid was bonded to the hull and showed the two parts coming together...  As we were watching, I said to my daughter I wonder what plant they are in, because it still was unclear as to what brand of boat was being built.  The next shot was the deck coming out of the mold with fixtures mounted and then the camera panned the internal cabinetry and systems mounted in the hull.  I still couldn't figure out what brand it was.  Well, near the end of the segment, it showed the finished hull going into the Test Pool.  At that point I said to my daughter that the stern looked like one of the 5 series Catalinas!  Sure enough, the camera then showed the boat sailing, as it panned back to get the full side of the hull, the Catalina model at the aft quarter section of the sheer stripe was seen then the camera pointed up to the sails to show the Catalina red and white diamond on the mainsail.  Funny that the name of the segmant was "Luxury Sailboats"!  I guess we can all feel proud to be in the same camp as Sabre, Oyster, Passport, Hylas, etc.  :clap

Main Message Board / "Potting" balsa core with West System 610
« on: November 13, 2014, 07:26:28 AM »
Hi everyone,
I'm planning on installing some thru-deck fittings and read through Mainesail's "potting" technique using a dremel.  Has anyone used the West System 610 product in a cartridge?  This stuff already has the epoxy, hardener and thickener built in. All you do is squeeze it out and mix (or use mixing adapter on the end and it comes out pre-mixed).

Not sure if this epoxy product is appropriate for doing the job of sealing the balsa core.


Main Message Board / Butyl for marelon/plastics
« on: October 31, 2014, 10:01:06 AM »
Hi All,
I know Butyl is the best way to seal stainless fittings, but is it also good for marelon or plastics (I'm not talking about below the waterline thru hull).  What I mean is a scupper thru hull that is above the waterline.
