Windsong: Cleaning the Bottom

Since hauling Windsong out of the water I have been focusing most of my energy on her hull below the waterline. My goal was to get the hull to the point where it could dry out for the rest of the time on land. This would mean removing paint and the gel coat (if necessary) and then leave the hull alone while I worked on the rest of the boat. Fiberglass boats do in fact absorb water through osmosis (what creates blisters). The hull needs to be completely dry before I apply the planned epoxy barrier coat (protects against water absorption) and then paint.

I had researched many different ways to remove paint from the bottom. The most common choices are to sandblast, grind, use a chemical peeler, or just old fashioned muscle and scraper. I opted for the simple method of scraping with a cheap paint scraper from Home Depot. The bottom paint was loose enough where the majority of it came off with the scraper. I would scrape a section of hull then go back and sand away the remaining paint down to the gel coat. I started at the bow on the starboard side and worked my way back. Here is the hull after the first weeks work: Removing the old paint to the gel coat revealed quite a few small spots where fairing compound was used in some sort of repair. It also revealed the blisters I feared would be present. The worst case scenario in my mind were thousands of small blisters all over the hull. But what I discovered were isolated, larger blisters averaging about 3-4″ in diameter (some larger some smaller). When I found a big blister I would drill into it with a countersink bit to release the fluid inside. The fluid […]

Windsong: The Haulout

he Monday after we sailed Windsong into St. Augustine we finally hauled her out to begin the massive rebuild. I had been anticipating this moment since I bought the boat about a year ago. I had never seen the hull below the waterline but knew a little bit of what to expect. I dove down to check the bottom once, but it was too murky to see anything. I could feel blisters however near the waterline so I figured I would have a few of them. Windsong was kept in warm Florida fresh water for a long time without a bottom job, ripe conditions for blister problems. I feared that she may have a case of full blown pox – a condition of thousands of tiny gel coat blisters covering the entire hull. This was the worst case scenario and I wanted to be prepared for it. I didn’t expect any other major problems with the hull, though I anticipated some damage on the keel from when we ran hard aground. During the past year I have been studying all that I will need to do to the hull depending on its condition.

It was a gross morning with a ton of rain. We hauled her out in the downpour and I got a first look at the bottom Proud owner 🙂 After the haul they gave her a good pressure wash. There wasn’t much growth on the bottom, just some slime. She had only been in salt water for about two months and the water was pretty cold the whole time, so barnacles didn’t get time to grow. The pressure wash was taking off chunks of old paint that had begun to deteriorate over time. It turns out, the gel coat blisters I thought I felt were actually just […]

Bilge pump

This is a blurb I wrote a few months ago and had saved as a draft. I forgot that I hadn’t published it. So a bit late but here it is.

The reason we went up to the boat for the last few days was to clean her up a bit and get the bilge pump working again. A few months ago the bilge pump had come on continuously and for some reason couldn’t be turned off. I’m not sure that Angela even knew it was the bilge pump as it is a really nice diaphragm unit that sits up in the back of the engine compartment and doesn’t really look like a what you would think a standard bilge pump would. It ran for a  day or two before she found out where the noise was coming from. It’s pretty quiet when running dry. Finally she just cut the power line to it to get it to turn off. I think what happened is that the automatic switch went bad or the control panel for it went bad and left it running.

Me in the engine compartment reconnecting the power to the bilge pump.

The new panel I ordered to replace the old one.

The Sea-Dog 422035-1 provides an audible and visual means of warning that water level in your bilge is beyond your bilge pump float switch level and it has a control switch to select between automatic and manual mode of the bilge pump.

REINFORCING SIDEDECKS: s/v Gracie Emmett DE32

By: Duane Nealon

The side deck sections along the cabin area have clear spans with no bulkheads or built-in cabinets to give support to the underside of the side decks. These deck areas always flexed, a condition that was attributed to lack of support.

Recently, a prospective buyer was convinced that the flex in the deck was a sign of deck delamination and core deterioration. Within days, a fiberglass expert was called in to assess the situation. Several core samples were taken on each side of these areas, which concluded that there was no delamination or core deterioration.

However, the thickness of the fiberglass and core on these sections of the side decks was relatively thin, approximately ½”, which was surprising because when installing a cabin top head vent, chain deck pipes, and the cockpit hatch, the core samples were much thicker (3/4” – 1”).

The approach taken for this project was to remove the interior layer of fiberglass and reinforce the side decks from the underside. This approach was made much easier as the result of the removable Spectropile headliner that was installed (see recent Gracie Emmett headliner article), and the fact that there were no interior built-ins that had to be dismantled. Step one was to cut and remove the interior layer of fiberglass below deck.

(Another possible option would have been to cut the interior layer of fiberglass on three sides to inspect the core and signs of delamination or determine if there was any latent moisture, thereby, allowing the forth side of the fiberglass panel to remain intact and provide a convient hinge to reattach the fiberglass […]

Hawse Pipe

Another project that needed immediate attention was the port hawse pipe on Valkyr. I was walking up to her on the dock and just happened to notice that the hawse pipe was about to fall off. So I pulled it all the way off. I thought some of the rest of you would be interested in how the sides of the boat here are designed. It is hollow up in there.

This is a project that  needs to be revisited. I found that the holes the bronze wood screws are going into need to be re-glassed and drilled again. (you heard it correctly all that as holding it in is some wood screws.  Actually what it needs is not wood screws but machine screws that go all the way through to the plate on the inside and I need to tap threads into the plate and and have the bolts hold them together. Right now I have new bronze screws in place and lots of 3M 4200 as bedding compound. It is working but not as strong as I would like it to be.

While I had the hawse pipe out I polished it up also. here are some before and after shots. I just used a little generic polishing compound and some 3M 1500 grit sand paper. I tried using a scotchbrite pad but it just didn’t get the job done. The 1500 grit got the job done and left a very smooth surface. Smoother than it was to start with.

And here it is installed. I  actually had to take it back out after this and turn the hawse pipe over as it it didn’t fit flush to the plate on the inside. You can see this in the picture.
