Our Catalyst superyacht tender has made massive strides following the Christmas break. In the last newsletter, we left off after removing the hull from the mould.
Now, all the interior girders and frames have been installed and the hull turned right-side-up. Most of the bulkheads are installed, the lower cabin superstructure has been constructed and is ready and waiting to be installed, the cabin roof has been completed, and the ‘floating floor’ cabin interior structure is nearing completion. The ‘floating floor’ is installed over the structural cabin sole to fit with the raised side deck designs. The raised side decks are a custom feature requested by our client to create water sports storage garages underneath.
In addition to the side decks, the owner has added a number of upgrades during the build, making this arguably the most luxurious and well-equipped Catalyst constructed to date – she is going to be a very impressive boat.

Aft global bulkhead installed – note: the boat is still upside down in this photo.

Simer installing a “Z” frame (that is the shape it makes if you look at a cross-section of it).

The first fuel tank under construction at the fabricators yard.

Inflatable tube fender topside mount support bracket – this will make more sense after you have scrolled down a few more photos (those random legs are some of the team installing structure in the hull).

???? – It is being sanded smooth though - so there are no sharp points (see below for what we used this for).

Cockpit sole dry fitting. You can also see both fuel tanks are installed & the forward cabin/storage areas are underway. Yes, this boat has a two-berth cabin.

The inflatable tube fender topside mounts were installed—yes, that is what the section of half pipe was for. Specially shaped moulds were made to make the complex concave sections required to follow the curve of the bow.

And here are the inflatable tubes being test-fitted.

Foredeck being test fitted and marked up for trimming to size - before final glue down. That is the lower cabin superstructure's initial test fit in the background as well.

And this is the lower cabin superstructure test fitting from the port side - with the aft structural arch.

This confusing picture is actually the floating cabin interior structure under construction. Once installed, it will make a lot more sense, which will be in the next update..

Our anticipated launch date is the end of the third quarter of this year. We will be very excited to see B74 in the water as she is a totally unique machine – there is literally no other boat like her in the world.
However, there is still plenty for the team to do to meet that deadline.
