This blog documents the modifications necessary to get seaworthy (warts and all), then the adventures (hopefully) on board our Trailer Sailer 6.1 metre Jarcat6 Catamaran, Kismet.

Rudder box Reduction & Trailer modification

I spent a couple of hours sanding down the rudder boxes at the position where I want to re-mount the gudgeons yesterday. I had to take about 2mm off the width of the boxes to allow the gudgeons to slide on reasonably easily. Once they were sanded back enough I applied two coats of thinned Bote-cote to the now-raw timber - allowing a day in between coats.

The rudder box below is precariously balanced here so as to allow the epoxy to settle into the gaps - see the reason below. I have also marked the gudgeons as to where they will be used as they vary in gap slightly.

I added some filler to the left-over Bote-cote and dribbled it into the un-sealed gaps in the rudder boxes. This apparently should have been fibre-glassed during assembly - but no...

I have sealed about half the gaps so far. It's a good use for left-over Bote-cote each time I mix up a batch.

On other matters - I have been gouging our driveway curb each time I take the boat on and off our property. (I think there is a similar gouge in Vicroads driveway.)
You can see an old and a new gouge here.

The rear double rollers on the trailer had not had the excess taken off the vertical bars so it left gouges every time the trailer went into a dip - like a driveway. It's not good for the trailer or boat when the trailer gets hung up on the curb either.  I'm REALLY hoping that I don't need the rollers to be adjusted up!

Rear right removed and cut down (with hacksaw - about 15 minutes each bar).

 Cut-down rear right.
I did the right hand side a couple of week ago but I could not get the left side off this morning (no matter how much cajoling I did with my hammer) so I took to it with the angle grinder and a cut-off wheel. I painted it in situ.
It was a lot quicker - but noisier and pretty fiery. I carefully figured the angle for the spark trail so as not to harm the boat. Sorry no pictures as no-one else was home.
