Ship in drydock

Didn't catch the name of this ship in drydock in La Plata, but it looks impressive.

Finally sailing again!

After three months of repairs and modifications, Issuma is finally sailing again. Still a bunch of things to finish, but it is really nice to have a boat capable of sailing again.

The picture was taken on a pleasant, sunny, daysail from Buenos Aires to La Plata.

Fitting the new day tank
Richard
Mon Jan 26 0:00:00 EST 2009, San Fernando, Buenos Aires, Argentina

The new day tank fits entirely into an existing access hole in the bottom of the cockpit. Nuts were welded to the underside of the steel cockpit bottom to bolt the tank to, and here the paint is being ground off in preparation for welding the nuts in.

New day tank

The "day tank" is a fuel tank that supplies the engine for a while (not really a day in this case), and is refueled from other tanks in the boat. The day tank simplifies switching between fuel tanks, and can be used to help separate out water and dirt in the fuel (being heavier, they sink to the bottom and can be removed if there is a drain at the bottom of the tank).

The old day tank was a cylindrical plastic affair, with fittings Sikaflexed (Sikaflex is a brand of glues and sealants) into it. It had been leaking, and the Sikaflex used to repair it was getting into the fuel and starting to clog the fuel filters.

I wanted a bigger day tank (the old one was only good for about three hours of motoring) that didn't leak and would help separate out the water and dirt from the fuel. This is the new day tank, made of stainless steel, much bigger, minus the fittings, which were installed after the tank was installed. The new tank is built to fit into an existing cutout in the cockpit floor.

The Disarray

There are a number of jobs going on at once on Issuma, and the pilothouse is now a mass of disarray.

The pivoting instrument panel has a new white rectangle below the depth finder. What changes are happening there?

The GPS is being replaced. Sadly, the french GPS that came with the boat died. This likely happened when replacing the house batteries without disconnecting the solar panels, which spiked the voltage up.

The new GPS is a Furuno. The manual indicates there are data averaging settings that will will allow it to display believable courses and speeds like the old one did (unlike Garmins which never seem to do so correctly).
New pulleys for keel
Richard
Sun Jan 25 0:00:00 EST 2009, San Fernando, Buenos Aires, Argentina

The pulleys that are used by the winch to raise and lower the keel were badly corroded. The wire kept slipping off one of them, and two others were seized up and would not turn. All were replaced with new stainless steel pulleys with more grease nipples to make maintaining them easier.

Hurray! Great to see the pulley system fixed up and easier to grease. Did you manage to get the cable soaked in hot tallow? I guess work is also happening to fix/improve the centerboard restraining pads.
Wed Jan 28 11:35:18 EST 2009 | Richard Hudson
Cable still needs to be replaced, and is still greasy. The bad keel pad had the bolts cut out and it was fixed (internal O ring failure) and reinstalled. Spare units did not fit the holes.
Something completely different
Richard/Victoria
Mon Jan 19 0:00:00 EST 2009, Buenos Aires, Argentina

The boatwork continues to progress on Issuma. The other night we went to see a really good band from northern Argentina, La Bomba del Tiempo. The band played outside on a hot summer night, and the crowd loved the band. The girl in the picture is one of several people who were being passed around through the crowd.

Buenos Aires is a really fun place (though a bit too hot in summer).
Painting the bottom
Richard
Sun Jan 18 0:00:00 EST 2009, San Fernando, Buenos Aires, Argentina

The old antifouling (paint that is put on the bottom of a boat to discourage barnacles from attaching themselves to the hull) was sanded off, the underlying paint inspected, and epoxy paint then put on. The purpose of the epoxy paint is to electrically insulate the steel hull (which is actually coated with zinc in this case) from the copper that is in the antifouling paint.

The first attempt at putting the epoxy on didn't go well, as it was not mixed well enough (it comes in two components, that must be mixed together correctly) before painting. Epoxy that is mixed incompletely or incorrectly results in paint that will never "dry" (cure). The following day, the incorrectly mixed paint was laboriously removed so the painting could be started again.

The first coat of epoxy is on. The zebra look is from running out of white and substituting black (the next coat will be entirely black).

Did any interior work like new tanks get done or will that wait for another time?
Fri Jan 23 0:15:34 EST 2009 | Richard Hudson
The day tank is being replaced with a bigger one. The welders were not able to put any more tanks in at this time.
