Water Tank Project – Phase 6……progress report

No Comments 08 July 2012

It’s time for an update on Velkommen’s water tank project. Mid August of last year was ‘Phase 5′ and then there was the little exhaust elbow repair in January.The last couple of months have been dedicated to the Hurricane heater. It was upgraded to 2012 standards by Gordon Jensen of Latitude Maritime.  The heat sheild exhaust blanket was done by National Marine Exhaust.  The installation positions the heater partially under the port exhaust elbow (the former problem child) with just enough room for the hydronic lines and the Hurricane exhaust to pass beside the  engine exhaust.  Both the inboard and aft panels of the heater are removable for service, so the current placement gives as much access as possible within the challenging confines of a lazarette.  Everything is mounted on rubber pads to isolate vibration and minimize chafing.  I puzzled a while on the placement and containment of the start batteries.  I think I came up with a creative solution.  It is simple and effective and I’ve never seen another like it.

I even got Ray Robinson’s “seal of approval”, and that’s really tough to get.  He slid through the hatch, inspected everything thoroughly, frowned and said, “Damn thing’s overbuilt”.  SWEET!  That is just the way I want it.

Exhaust Elbow Repair

No Comments 12 January 2012

Even products that look absolutely flawless can can occasionally have problems. Right before Christmas I was stretched out in the lazarette attending to a little detail that I wanted to tidy up.  A wire going to the starboard courtesy light was wound around a hydraulic line.  It didn’t bother anything, but without much effort it could be untangled and everything would look much neater.  I had to get my 2XL self into the far corner and reach up under the new stainless steel exhaust elbow to begin.  My sleeve got a little wet; that didn’t seem right.  A little drip seemed to be forming on the underside of the exhaust elbow and one of the welds was not perfectly smooth.  There was a rusty little spot on one of the new ribs that hold the water tank platform.

I didn’t relish the unanticipated job of removing the elbow.  The exhaust hoses are short and stiff and not very forgiving or flexible.   So everything got put on hold until the New Year arrived.  The starboard exhaust elbow came off  easier than expected, but when the exhaust elbow gets removed all the water that is in the muffler spills into the bilge……and I had it so dang clean, too.   Just so you know:  a muffler that looks like it might hold 5 gallons of water spills about 10 gallons of water into the bilge.  Trust me.

National Marine Exhaust was excellent.  Scott built the elbow about 18 months ago.  He polished the weld with a wire wheel and it looked fine, but when he put the torch to it , a big crevasse opened up.  So it got rewelded (extra-beefy) and we added a bonding tab for good measure.

Reinstallation was a joy.  There are not many places to get leverage or to pry against.  But with help from Mark Hanger of Mark’s Marine Repair the elbow finally gave  up and slid into place.  Usually it’s “two steps forward and one step back”; this was probably “one step forward and two steps back”.  But it emphasizes the value of doing business with good local folks who treat ya right, long after the check has cleared.

Starboard Water Tank Update

No Comments 22 March 2011

I admit it has taken some time, but then I don’t do water tanks for a living…..and if I did, it would be a wicked way to diet!   The image shows the inboard side of the starboard pair of tanks.  Made in the U.S.A. by Ronco Plastics, 30 gallons each: #B-189  Everything is solid; all nuts and bolts are stainless.  Next,  the platform gets mounted on the outboard stringer and ribs, just 1/2 inch away from the muffler.  Then the tanks get plumbed together and hooked up to the pump.  Half of the fittings will get capped off.  When I ordered the tanks, I thought it might be better to have too many rather than too few.
Starboard water tanks - forward Starboard water tanks - aft Starboard water tanks - outboard

The platform for the port side just needs a few more coats of paint.  The floor of the lazarette is getting the same light gray treatment.  Three coats of primer and three coats of gloss.  Kirby’s Light Gray #25.  A web search pointed me to Kirby’s by way of the Woodenboat Forum and Rejuvenation Woodworks.  I called the Massachusetts facility to get their input on my project, since I’m applying it to both wood and fiberglass.   I like the non-technical application.  Thin the gray-tinted primer with a little mineral spirits and apply to a clean surface with a brush or a roller or whatever you have.  The same goes for the gloss coat except penetrol is used instead of mineral spirits.  I goes on easy and dries hard; just right for a 1st timer like me.  Easy is good.  Progress is good.

Water Tank Replacement and a Few Other Things – Phase 1

Water tank pieces.

This project has been on the back burner for quite awhile.  When we bought the boat there was a little water in the lazarette, not enough to be a problem, just annoying.  A large local boatyard replaced the mufflers claiming that a clamp had been overtightened, cracking the fiberglass glasspack.  All of their work was quite nice and quite expensive, and much of it has had to be redone.  I suspect one of the fiberglass exhaust elbows has deformed with heat and is letting a little water excape.  As soon as I get the area cleaned up I’ll have access to all the corners and be able to fix the problem properly. 

The introductory paragraph leads to the water tank.  The original tank was supposed to be 100 gallons (actually it was 84) and it sat atop the stringers in the center of the lazarette.  It was mounted well and worked just fine, but it was too big to crawl around and it was too big to come out of the hatch.  Consequently, access to the Hurricane heater, remote compressor for the Sea Freeze refrigerator, the Magnum Industries inverter and, of course, the exhaust system was was way more difficult than it should be.  Plus, alot of good storage space was going to waste.  So I drained the water tank and grabbed the DeWalt sawsall and the first thumbnail shows the result. 

lazarette_tnDang, there is alot of space down there if I can just rearrange things a bit.  The hatch opening I have to work with is 26.5″ wide by 27.5″ long and it’s 15″ deep to the top of the striingers. The space between the stringers is 16.5″ wide by 8″ deep. It will be nice to get the area shipshape and user friendy. 

Hold on….I just took a day to do some cleaning and inspection of the area.  It looks like the through-hull transducer could have lost it’s seal and is leaking.  The transducer is located just forward of the gray starboard battery tray and below and aft of the Magnum Energy inverter.  I cleaned up the area and have now stuffed dry paper towers around it.  We’ll see if they get wet.
