I tawt I taw a Ventnor Moth.

One of the things I didn't mention in my earlier posts about this year's National Regatta is that Erky's widow, Alma, had decided to offer his vintage division Ventnor Moth Boat for sale.

John Z. decided to step up to the plate and is now the new owner of Tweety.
The boat is in overall good condition and came complete with two sails, spars and blades.

But like all boats approaching 70 years of age, this one has her share of things to correct.

But there's nothing here that John can't fix.
Although Tweety's original IMCA sail number is unknown, she does have a Ventnor Boat Works production number stamped into the expected place--the forward centerboard trunk log.
She'll rest in John's shed until he has time to move her into his workshop.  Once fettled, she'll be a welcome addition back in the vintage division racing fleet.

Repairing Renegade's mast. First steps.

Some readers may recall that during my summer vacation I picked up an old Harry Cates-built Cates design Moth Boat.  If not a refresh can be seen here.  Work on this boat has been slow due to either 90+ degree heat or torrential rains.  Now that fall has arrived the temps and the rain are starting to become a bit more tolerable and so I've pulled out Renegade's mast for a spot of repair.

The mast has several problems but the biggie is this split in the luff groove starting at the point where the sail feeds into the groove.  It involves about 18 inches or so of the mast.

Dry run with clamps.

Packing tape to catch resin squeeze out.  Note the good sized gap remaining even with clamp pressure.

Rag on a string to wipe excess resin out of the groove.

I used colloidal silica filler for maximum strength.

The clamps stayed on over night.  I plan to reinforce this repair, taking a tip from a fellow blogger over at the Lingering Lunacy blog, with some fiberglass sleeve. Far less messy than trying to wrap the repaired area with glass tape.  More on that once the sleeve material arrives.

A secondary issue with this mast is that years ago the varnish was removed and the bare wood left unsealed.   The wood is covered with small dots which I assume are mold colonies.  The entire length of the mast is involved.

I decided to test my theory with some household bleach.  This is a "before" shot.

This is the "after" shot.  Hopefully, the damage is limited to the  surface layer of the wood.  We'll see if a good sanding will get me down to sound wood.

The Resurrection of Swiss Miss Part Three: Finishing touches

Picking up from the last post, with the deconstruction finished, Joe started going the other way.  Here we see the deck stringers  which tie the aft cockpit bulkhead to the reshaped transom.  Note the judicious use of carbon (perhaps over foam core?) as an attempt to add stiffness to the floor of the hull and reduce the tendency of this old solid glass lay-up to "oil can". 

Joe typically embeds lok-nuts for the transom hardware, chain plates etc. in thickened resin to make them captive.  This makes hardware removal for painting and maintenance much easier and also reduces the number of inspection ports required for access to hard to reach nuts.

Another view of the aft end of the hull.


Forward most bulkhead. 

Shear clamps.


Joe took advantage of a dry spell of weather to paint the exterior of the hull.  My old Shelley, Say When can be seen in the background.  She's now owned by a junior sailor.







A far cry from when I brought her home.

Paint dried.  Returning to the interior furniture.  A new dagger board trunk.


This photo shows some of the timber support jig that Joe used to keep the hull in alignment.


Another view of the jig, from the bow.

The curves in the cut down and lightened bulkheads define the shape of the side tanks.

A bit of carbon to reinforce the struts coming diagonally from the king post.  Note the small ply gussets used to strengthen the center beam for the fore deck.



These curves define the shape of the well deck.


Additional framing for the side/seat tanks.





Joe first made poster board patterns for the decks and side tanks before cutting ply.

The resurrection of Swiss Miss: Part Two

After Joe got the boat home he quickly decided that the cracked decks and side panels which were providing sanctuary for water logged flotation foam needed go in order to save the hull.

Port side decks were the first to go.

Joe basically gutted the hull.

When first laying up the hull in the 1960s the workers at Fletcher Marine Products painted the  words "smile" and "wipe out" inside the hull.  These little secrets have been waiting over fifty years to be discovered.  What's hiding deep within your boat?!

"Wipe Out"  No doubt a reference to the tippy nature of this narrow water line design.

Once the decks and support structure had been removed, Joe squared the floppy glass hull with timber to keep her from twisting during the installation of bulkheads.

The first two bulkheads taped into place.  The clamps seen here hold a bit of timber while resin kicks. The timber strip will define the new top shape of the transom and give aft deck stringers something to land on.

Keepin' her on the straight as well as the narrow.  As can be seen the original dagger board trunk was also removed.  Joe closed the hole where the original trunk was located and move both it and the mast position to the same locations as on a stock Mistral.

The old glass decks and side tanks ready for the dustmen.  Note the bathroom scales on the left side of the photo.  Joe kept track of how much the hull weighed as he added structure back to the boat.  More of Joe's magic to come in a day or so.
Oh, and remember the comment I made about the excessive roached, low aspect "transitional" sail on the previous post?  I just rediscovered a photo of those two sails, one of which is a "normal" low aspect sail, that I placed on top of the big roach sail.  Vive la différence!
