Alberg 30 refit: Hull To Deck Joint Failure Photos

I finally got around to taking a further look at the hull-to-deck joint. I can't really tell why it failed but my best guess is the lack of sealant/joint compound. I don't see any evidence of it in the failed portion of the joint.
Here is where the joint looks normal. That sealant appears to be from the factory.

I took some of the repair sealant out and cleaned up what I could, I am hoping I can simply cinch back into place.  

A different angle and a better look at just how far it has separated.

Another angle looking down on the hull-to-deck joint. 

So as of right now the plan is to strip off all the old wooden toe rails, genoa tracks, and anything else that is attached to the toe rail. After that I will repair the lifted part and fiberglass the entire joint all the way around the boat. That is the plan for now.

Alberg 30 Refit: Hull to Deck Joint failure

This week has been very productive. This is because the outside temps have fallen into the mid 80's with little humidity, making for a very enjoyable evening and an easier work day. This has led to some boat work. With the bottom of her hull drying out I was able to begin removing items from Sal's top deck.

You can see all the stanchions and the bow pulpit removed.

In this photo you can see where the bow pulpit base plates were mounted. I am not 100% sure when the last time any of this stuff was rebedded (sealed) but I am finding wet core material in her decks. I'll explain the core in a minute.

Here is a picture of Sal's mast base. 

Here it is again with the base removed; looks nasty. All of her core is rotten. This is a common problem on Alberg 30s of this vintage. Unfortunately her decks are worse off than I previously thought.  

Here is a good photo of  how the deck is made and how it should look. In this photo you can seen the yellowish-brown balsa wood core. On either side of the core you can see the fiberglass which adheres to this core to make a nice sound rigid structure. When making a hole on the boat one should seal these areas of exposed core to prevent water intrusion. The problem is many manufacturers never took that extra step and over the years water made its way into the core. With no way out for the water, it just sits there and rots the wooden core.

Here is a close up of the holes that were used to pass cable that went up the mast. Years of water intrusion has turned this area into a "soft spot" and there is now compression on the mast post below. That black stuff is wet rotten core.

On to Bigger Issues:
Hull-to-Deck Joint Failure!!!

While researching my Alberg 30's history online I found some forum posts about Salacia (named Dances with Waves at the time) having hull-to-deck joint issues. In the post, her owner described it as "Oil Canning" on the port bow. Ever since we purchased her I could see the evidence of where the repair had been made. Today I got a really good look. I'm not happy about what I found, can be fixed.

Photo of Alberg 30 hull-to-deck joint. This where the manufacture fastened the deck and hull together. These boats were made in two separate pieces and then jointed together. This joint is crucial to the overall structural integrity of the boat and, ultimately, to her seaworthiness.

Here is a photo I pulled from (Alberg 30's big sister, the Alberg 37). It is an exact representation of how Sal's hull-to-deck was built. Both boats were manufactured by Whitby Boatworks in Canada so it is no surprise the joints were built the same.

Here is the failure area. You can see the deck is lifted from the hull. The owner at the time just filled the gap with some sort of sealant and kept on sailing....

Here is the hull-to-deck joint that looks normal, with no gap. I will clean these areas over the weekend and post better photos.

As I continue to dismantle Salacia I continue to find issues. I am not unhappy about these things, and I am actually glad they are coming to light so I can fix them properly and feel confident in her seaworthiness.

Alberg 30 refit: Dimples on her bottom

It has been very hot and humid here lately; and so I have not had the drive to go outside after work to get anything done on Sal. Although last Sunday I did wash her down. Her once-white decks were a dark shade of blue from all the boat sanding. After that I scrubbed the bottom of the the boat with just plain water and a scrub brush. I did this to rinse the sanding dust and to get a good visual of what has to repaired now that the paint is gone.

With all of the paint removed from the bottom of the boat it is now time to begin preparations for the repair of the hull imperfections. I am not 100% convinced that what I originally thought were blisters are indeed actually blisters. The more I look at her bottom and the affected area it looks to me like all the little voids are just air pockets from poor lay-up of gelcoat. This was pointed out to me by a blog follower (thank you, Ariel CD36 ) . I believe he may be correct. Does this make it any better? not really. All these little holes have to be filled and sealed. Let the repair process begin!
Most of the small pin holes are in the dark shaded areas you see in the picture above.

Here is a close up of an affected area...all those tiny dark spots are pin-sized holes, though some are large enough to see fiberglass laminate in them.

My plan is to drill each one of those pin holes with a broad countersink bit. This picture shows the one I've been using. I will drill in about 1/8 of an inch to open up the pin hole enough to get any contaminates out and make it large enough to make a good fill area for the epoxy filler.  

Here is the same area after I hit each of those pin holes with the countersink bit creating an open dimple in the gelcoat. You can see it opens up the pin hole quite nicely and provides a  good large surface for the epoxy to adhere to. This is only one small area, maybe 4" x 4". I have been doing this to the bottom for a week now and only have a very small portion completed. It's going to take a while.

In the meantime I have started to turn some attention to the decks. I have to remove all the fittings, hatches, railings name it, it has to come off to begin deck repairs.

First item off was the seahood above the sliding companionway hatch (you can see it in place in the deck picture above). This seahood hatch protects her cabin from sea spray and ultimately keeps water out of the boat. 

 Next on the chopping block are these lovely speakers some previous captain decided needed to go right here.
They cut 4-inch holes in the boat to install these.   ??...!!
I'll be kind and assume they just liked music more than they cared about the boat. Everyone has different preferences.

As the summer rolls along I am trying to finish some other side projects that are going to bring in some refit money. I wish I could spend more time on the boat but with the heat and humidity lately, progress will be slow for probably another month.

Alberg 30 refit: Wet Hull

Now that all the paint bottom paint has been removed, (well about 90%, I still have a small section left on the starboard side) I can begin to formulate a plan to repair the blisters. But that repair is going to have to wait a bit...
...because after getting down to the gelcoat and letting the boat sit for a few days these dark spots started to appear on the hull.

I smeared them with my finger to make them go away thinking it might have been dew or something. 

Well that wasn't it either; the dark spots returned. So I believe there is water in the gelcoat and the fiberglass laminate. The paint must have been holding the moisture in. I do not believe it is a lot of moisture but I will have to let it dry out before beginning repairs. Epoxy will not adhere to the hull unless it is completely dry. I am ok with this since I am in no rush. The boat is covered and has been out of the water for a year now. Actually, having said that..I really do need to get moving!
That big white spot is the previous owner's attempt at filling an old hole in the boat where there used to be a saltwater intake to the galley sink. The patch worked but it was not done properly. I believe all he did was fill the hole with an epoxy putty and some of it was still wet when I sanded over it. I was always a bit leery of the repair because of other things the previous owner had done in a similar slap-dash manner.  I will have to grind all that out and repair it correctly. 

So on to the next big job: Removing all the deck fittings, hand rails, stanchions and teak from the topside decks.

Alberg 30 Refit: Happy 4th of July 2015

Happy 4th of July!
Happy Independence Day, America!

This picture was taken May 22nd while on the ferry. I have actually seen a few fireworks shows this year while running the ball park ferry. I hope everyone has a safe a fun 4th. I wish we could be with friends and family but I have been called in to run an extra ferry to handle tonight's fireworks show in Norfolk.
On to boat work update:
This what I started with yesterday, a scraped starboard side

 And this is how the boat looked after about 4 hrs of sanding! 

I have question all you Good Old Boat guys, there appears to be a red gelcoat  stripe all the way around the boat at the original waterline? The boot stripe on the boat appears to be 3-4 inches higher than the original waterline. I heard that some Alberg 30 sterns appeared to sit low in the water. Our Sal did not. She sat quite nicely; I wonder if this is because someone altered the waterline. 

Because I did not want to get too dirty working on the bottom I decided to take more stuff off the boat in preparation for work inside. Salacia has a small volume interior compared to some 30ft boats and I am still amazed at how much stuff can be stored! I feel like we've already offloaded so much and there's still more to be done, 

Work continues, and I am hoping that the nastiest part of the job is just about over, as I finish up the bottom paint removal process. I will then begin repairs on the bottom in preparation for her barrier coat.

Have a safe and relaxing holiday weekend!

Alberg 30 Refit: Bottom paint removal, starboard side & a Couple of Young Cruisers

It's been really hot here the last few weeks. Humidity has accompanied the heat, and heat indexes have been well over 100 for several days now. Regardless, today I just could no longer stand not getting anything done on the boat. I suited up when I got home and started the starboard side.

I am happy to report that this side of the boat's gelcoat seems to be in much better shape. You can see that the blue gelcoat extends much further down the hull and there does not seem to be as many blemishes. What a relief!

Armed with the scraper, I got to scraping.

A little elbow grease, sweat and determination was all that was needed!

Heat and paint scraping aside, I met some like-minded cruisers yesterday. After finishing my shift on the ferry I noticed this salty-looking cruiser had pulled into the free docks in Portsmouth. I had to go over and talk to the crew. I was immediately greeted by two friendly cruisers, Andy and Anna, who were sailing their sturdy Mariner 31, Jumble. They were headed to New England from San Diego, CA. They invited me aboard (I was curious to see their stove arrangement), and I could have chatted with them all night. We exchanged blog info and I snapped this photo before heading home. Follow them at
Fair winds Guys!!!

Alberg 30 Refit: Bottom paint removal continued and hull blisters

This evening I finished up the nasty dirty paint removal task on the port side of the hull. During the last few months I have been pretty busy with work, family and other projects and I was becoming frustrated and worried that the refit would never progress. I had piddled around here and there but no major tasks were getting done. Fortunately, this has changed. I made it a priority to get this refit rolling.

I had been using a 6" sander to remove the paint. That thing made all kinds of dust. It removed the paint but was a bear to use. I decided to try scraping a majority of the paint. This turned out to be a great decision. In about 4 hours time I had scraped almost the entire side. 

After scraping a majority of the paint, sanding with a 5" Bosch orbital sander made getting to the gelcoat quite easy. Another 4 hours and I had 2/3 of the port side hull down to the gelcoat.

Working away at little bit at a time, I put in 2 hours last night.

Using the trailer as a bench and stool has come in quite handy.

Another angle of the sanded hull

Here's where the bad news starts. My Alberg is full of blisters (water intrusion), This is a good example of one. From what I can tell this is not a new problem and one that someone tried to repair long ago...about 6 layers of bottom paint ago to be exact, so maybe 20 years ago....who knows???

You can see the hull issues better in this photo. That discolored area which extends all the way to the stern seemed to be some severe crazing, and is full of blisters

The red dots appear to be old blisters that were filled and the other dots are new blisters. 

As you can see from the pictures I am making progress. I seemed to have opened a can of worms here on the hull. I surely want to fix the issues as best I can, but I also want to be sensible about the repair. I am devising a plan now to use West System epoxy for the repairs, and until then I'll be sanding the starboard side. More to follow!
