Stay up to date with our latest project, building a 24m Expedition Motor Yacht in Whangarei, New Zealand.

The big day has finally arrived, and after 2 years of construction, Circa 24m # 1 "Mollymawk" has finally made it to where she belongs. Over the next few weeks she will undergo commissioning and calibration of all of the on board systems and equipment, and will then undergo extensive sea trials in a range of conditions to monitor and record her performance and handling. She is a credit to all of the team at Circa Marine, our sub contractors and suppliers.

A big day today, Circa 24 #1 “Mollymawk” is sitting pretty in the early morning sun preparing for launching very soon.

 

More photos and updates soon.

 

This is who we are, this is what we do.

Circa 24 # 1 “Mollymawk’ has made its way out of the shed and is sitting very pretty in the New Zealand Autumn sun, and later tonight she will begin the short journey to the launching facility. Over the coming weeks we’ll keep you posted on any developments, and after sea trials there will be a full magazine article with plenty more photographs and video footage.

It’s been a very busy couple of days here at Circa Marine.  A big milestone was reached for Circa 24m hull # 2 ‘Deo Juvante” as the superstructure was carefully lifted into place.  Construction doesn't exactly have a reputation for elegance, but there is a fair amount of skill that goes into every move, especially when coordinating two cranes!

In a previous post we looked at part of the heating system in our 24m boats, an important feature on its own, but without a well designed and installed insulation system, all the benefits from heating and cooling can be lost very quickly.  We have always looked for and obtained expert advice where we need to, so Circa has collaborated with companies in New Zealand and Australia to deliver a custom insulation package for our boats.

 

 

 

Very early in the design process, it was established that the owner had a keen involvement and well-rounded understanding of the desired comfort levels aboard. That focus on performance – fire, thermal, noise & vibration - continued with Circa Marine’s project team discussing in-depth details of best insulation practices with the Pyrotek NC team in New Zealand and Australia.

 

 

 

Through an open discussion of possibilities, what could and should be done – ensuring passenger safety and comfort,  Pyrotek used their extensive know-how, experience, & engineering tools for predicted transmission losses , calculated thermal performances in varying circumstances –  developing  a total comfort customised solution – encompassing materials for vibration damping & isolation, reduction of air-borne transferred noise and reverberation, incorporating thermal and fire solutions within the weight and cost allowances and delivered on time.

 

 

 

The internal aluminium plating and elements were coated in Pyrotek Decicoat T35 Thermal anti-condensation and corrosion insulation, this is a water-based spray on coating that combines thermal and vibration damping properties with further thermal and acoustic insulation such as Pyrotek Sorberpoly added above this in many areas.  Machinery areas have Decidamp Soundpaint, this is a high performance, fast drying, water based viscoelastic vibration damping compound with Thermal insulating properties.

 

 

 

In the voids and other spaces, Pyrotek Sorberpoly and Quadzero acoustic, and thermal insulation has been installed. A comprehensive System was developed for the Engine room and machinery spaces for thermal and acoustic isolation and fire protection.

The final result is an insulation package that exceeds anything Circa has ever installed in any of our previous builds, and will guarantee owner comfort in both high latitude and tropical situations.

As part of the design process, we wanted to make sure our boats offered our customers not only safety and economy, but also comfort, so we have created an environment that will be controllable and will be a ‘nice place to be’ when exploring the higher latitudes.  Circa Marine is taking comfort to a new level in our range of boats, with the addition of underfloor heating, a system we have never installed on previous vessels, yet it has so many benefits over traditional heating methods.

The heating system consists of John Guest “speed fit” Underfloor heating components combined with a high efficiency 24v DC Diesel Burner with variable output, which is fitted throughout the accommodation and living areas on the Circa 24m. This heating system is coupled with an extensive insulation package which has been developed by insulation engineers in Australia and New Zealand specifically for these vessels.

With traditional heating systems it is typical to experience hot and cold zones throughout the vessel and even within a room, especially the surfaces and floor tends to retain a cool layer of air around them and are typically cool to touch, with under floor heating covering a large surface area warmth will evenly drift up from the floor and through all the attached surfaces creating a consistent comfortable temperature that can be set to the owners preference within safe predetermined parameters.

It doesn't look like it, but the gantry crane clears the roof by only 15mm. Deck tread due to start next week.

Fitting of Engines, Genset, Watermaker, Hot water, plumbing, and electrical, whilst providing reasonable access always presents a challenge requiring experience & careful planning.

As with most manufacturers that design and build their own products, we sometimes say to ourselves,  ‘What if”  and that’s exactly what happened when we recently reconfigured the Circa 20m boat as a low profile option, so we thought, What if we applied the same low profile lines for the Circa  24m as the Circa 20m Adventure Cruiser, and so, we did...

We are happy with the look of the boat, lowering of the VCG and air draft and the option of adding a small option flybridge if desired creating an exceptionally stable and safe platform. 

Here at Circa Marine we have come to realise there are many different preferences and design priorities in the the passage-making community and vessel owners, whilst maintaining our core design we can offer quite a variation of design parameters to meet the needs of a wide range of sailors.

2020 has been a year to remember for us all, and I think it is one most of us will be glad to see the end of. Let’s all hope 2021 will be the year the world starts to recover and rebuild.

We feel confident 2021 is going to be a great year for Circa Marine. Our team is working incredibly hard on both of the Circa 24m vessels, with hull #1 due for launch in Q1 and hull #2 later in the year. With growing interest from around the world in these boats, plus our smaller 20m option, we are certain 2021 will see us announcing more new builds of these exciting new additions to Circa’s long history of building world class aluminium boats.

So from all the team at Circa Marine we wish all our customers, owners and followers, a very happy Christmas, and a happy New Year.

Circa Marine welcomes all to view this video of our team in action, in the hope one day you may visit in person.

We are truly excited to announce the newly developed low profile sleek Circa 20m adventure cruiser. A slick looking option.

This lighter sleeker version with no flying bridge, has a greater surface area to add extended Solar capacity, and a low VCG which lends itself nicely to a kite sail system which under typical conditions could provide almost total renewable energy living and propulsion. We believe this version would prove to be a popular addition to the range of Circa Adventure Passagemaker's

Circa were recently involved in the refit of an ex commercial workboat into a luxury charter vessel.  The extensive scope of work included a full strip out and refit of all the interior spaces, accommodation, helm, galley and crew quarters.  We also supplied and installed new upholstered headlining’s on all decks, as well as interior and exterior tables and furniture.

 

All of the work was undertaken while the vessel was alongside in Whangarei NZ.

 

If you are looking for a full or partial refit of your vessel, look no further, we offer the full range of high quality interior and exterior improvements from design, manufacture and installation”.

The last of the main structural elements was lifted into place today on our Circa 24m hull #1. In these pictures you can see the fly bridge roof being carefully lifted and positioned before being gently lowered onto the main structure, before being welded off. In the meantime the internal fitout of systems, engineering and interior continues at pace.
