Alberg 30 Refit: Mast Support Beam & An Unexpected Tent Shelter Repair

Happy Easter to all!
I've been delinquent in posting perhaps, but there has been plenty of work going on. The weather has been a factor lately too. February/March are typically the worst months for weather and that held true this year. Although it has been unusually warmer, the mild days have been sporadic and not really consistent enough to start any epoxy or fiberglass work.
We had a severe line of thunderstorms that came through toward the end of February and caused quite a bit of damage to my boat shelter. I feel fortunate that this is all that happened because no more than 30 miles to the west several people were killed by tornadoes from those same storms.

After assembling the tent I knew that it would have to be secured by straps or it would be blown away. I intentionally did not design it as a permanent structure so I could avoid problems with the city code inspector. For over a year and through several storms it has worked quite well...until recently. This failed strap is what I believe caused my tent damage. At its worst, the storm winds kicked up to near-hurricane speeds for for a brief 10-15 min window. It was during this period that the strap broke.

This picture was taken the next day, after I had already moved the tent off the house. During the storm, once the strap broke the tent became airborne...or at least tried to. In an effort to move to the next town over, the tent bent and twisted the front half of the structure supports and buttressed up against the side of the house. It caused some minor damage to my gutters which was not too big a deal. The damage was minimal and could be repaired.  I will note that even with the failed strap, our Sal was kept dry for the most part. It took me a few days to get the bent pieces replaced and I am happy to report the tent is back up and stronger than before.

The boat refit is coming along slowly. I have been gathering pieces and making a plan but execution of said plan has been a bit lacking. Work and side projects have been taking up a ton of time as I have been running the ferry both days of every weekend to generate money for more boat parts. A valid excuse when one is refitting a boat on a budget. As the weather warms up I will have both the funds and the time to pick up speed...at least that's the plan.
Lately I've been working on the deck beam and now have it ready to go back together.

Here is the deck beam on my "Liner" Alberg 30 all sanded and awaiting additional support. 

I will lay new layers of 1708 biaxial cloth in these low spots before bolting in beam reinforcement.

Looking to the port side of the beam; not as many low spots but still a few.

Here is the new plate that will be the back bone of the reinforcement and repair.

I am using this router table to help shape the piece of 3/8 G10 board.

A nice 1/4 rounded edge, this stuff works just like wood.

New piece clamped into place for a test fit.


After plate is mounted I will add a 3" wide beam aft of it. This beam will support the aft part of the mast step.

The beam will be made of 8 pieces of 1/8" thick G10 laminated together to form the new beam. That gap seen is caused by the deflection in the cabin top from original damage. I was advised to leave the deflection and just build the new support off of it. The gap will be filled with 406 thickened epoxy.

Same gap to port

Once all of it is epoxied in place I will make gussets from the face of the original beam to the new bottom of the laminated beam.

If you are unclear about the repair stay tuned, I hope to have it done in the next few weeks and I will post pics of process and product as it comes together. Once the repairs belowdecks are complete I will begin the topsides of the mast step. Once I get  the mast step back together I will pick up on deck re-coring. Much work to do but looking forward to it.

Thank you for following!
