Here we see the underside of the hull-deck joint of an newer Alberg 30. This photo happens to be the underside of the taffrail, inside the lazarette. The arrows point to the actual hull deck joint, which is glassed together with a strip of glass mat betwen the hull and deck. The joint is also riveted (highlighted by circles) to hold it tight while the resin cured.
While this photo is at the transom, the construction is similar to this sketch of the toe rail hull-deck joint.
In some places, this strip of glass mat dripped down from the edge of the hull flange. I ground these places clean to make a friendlier place to work for human skin.
As you can see, I've drilled out the rivet and also counter-sunk for a flat-head bolt.
I then through-bolted with 10-24 machine screws. It's not shown here, but I bedded the machine screws in 3M 5200 caulk before installing the washers and nuts. To prevent the nuts from vibrating loose, I used Lock-Tite on the threads. Nyl-Lock nuts would be another good approach.

Offshore Sailing
by Bill Seifert with Daniel Spurr
We went to a Windjammers lecture to hear Bill Seifert and I was impressed enough to buy
the book on the spot. I've heard a lot of people talk about ways to improve a boat, but
I've never heard one person suggest so many good ideas that I hadn't considered. Part
of the charm is the specificity of the suggestions. Everyone says you should secure your
floorboards, hatchboards and batteries. Bill shows good suggestions on how to do so.
The suggestions are very practical for the do-it-yourselfer, too. Many show how to
make or adapt inexpensive solutions. Tip #12 on closing the deck blower vents is one
that will pay off for me without ever going offshore. I'll implement that one to
stop the wintertime storms from finding their way belowdecks.
Besides modifications, the book also includes advice for operating offshore, cooking,
boat selection, dealing with bureaucracy, and more.
Bill Seifert has worked at Tartan, TPI, and Alden Yachts. He's a veteran of many
Marion-Bermuda races and now runs his own yacht management company. His tips are
born of experience--not of book-learning--and it shows. He obviously knows his
stuff.
