  History

 There are now three 'versions' of the Blaze.

 

The first thing to be aware of is that the hull shape remains unchanged since the inception of the Blaze, as does the rigging, apart from the boom and sail. The version 1 (v1) sailplan is easily converted to the v2 sailplan (most have now done this) so all versions of the Blaze are similarly competitive.

Blaze Mk1

The first version of the Blaze had a 10.2 sq metre fully battened sail. The main problem with this sail was that in medium and high winds, after a tack or gybe, the power would come on so quickly that it could easily result in a capsize.

In order to make the boat easier to handle, the Class Association brought in some changes in March 2001.

The changes made to the sail and boom were:

  • lowered the boom on the mast, with increased rake upwards towards the stern
  • use of carbon boom
  • redesigned sail - 10 sq metres with full battens at the top of the sail only

The change to partially battened sail means that the power can be spilled from the sail when required, making the boat less challenging in medium to strong winds.


Some changes were also made to the top deck moulding and racks. The stern post was increased in size to allow improve access to the pintel bolts and the design of the racks was changed slightly - with the outer tubes made of carbon.

Blaze Mk2

This second version of the Blaze was marketed as the 'Blaze X', but is now referred to as the v2

Blaze Mk3

The v3 Blaze is made its first appearance at the London Dinghy Show on the 2nd March 2008. It is the result of a detailed re-engineering of the boats deck tooling and a switch from polyester to epoxy. The builders Cirrus/Rondar say the boat will now be much easier to build down to target weight on a volume basis. The deck tooling needed to be replaced anyway and with 10 years experience the Class Association suggested a number of detail changes to layout and fittings. The Blaze v3 will also have an all Harken fit out, carbon boom and carbon wing outers.

The use of a custom carbon mast has been approved for 2013 onwards

New Sail Material

Class sail maker North have switched sail material for 2008 with Class Association input and this has greatly improved all around visibility. Early users have commented how this has improved their tactical appreciation and find it difficult to switch back to 'regular' sails!

Blaze Mk3a

At the launch, the builders have nine pre-launch orders for the new boat from a mix of class regulars and newcomers and expects more when the boat is first shown. The class has for some time experienced a desperate shortage of used boats and it is hoped that new boat orders start releasing more good pre-used boats.

1) The mast is the official Blaze class carbon mast - custom designed 50mm round section and specifically produced for the task.

2) Foils - Same material as last 5 years but now produced in CNC cut aluminium tooling. The tools produce a 'perfect' shape every time and with fine edges (just like the old glass tools did way back)  They return the foils to as they were when the first ones came out of the original tooling - and we do not need to waste any time in post production fairing.  Should last for the next 1000 boats or so...!

4) The latest Blaze deck is similar enough to the Mk3 produced by Rondar it does not warrant being called a Mk4 as the changes are not deemed significant enough.  The back is now very strong indeed and the Cirrus default will be NOT to have a bar across the back unless the prospective owner either wants one or if it may be of benefit - i.e. larger helms.  The resin now used is the well known 'SP' and the foam incorporated is uprated.  Cirrus also vacuum the mouldings using higher pressure now getting better consolidation and post-cure in a much more controlled way.  A few detail changes in the deck tooling produces larger kick bars and a more rounded rear rudder post.  The backing behind fittings for fastenings are improved as well - lots of detail changes but nothing major and most may not even notice but all changes have been made for good reasons! As before all hulls are produced to a common weight and are weighted before release using the electronic strain gauge system at White Formula - in effect the 'official' weighing for the class now.  Cirrus believe the latest boats are the best ever produced and at least the equal of virtually anything produced elsewhere in the UK and beyond.

1) Improved kick bars - larger and slightly curved at front to follow line of cockpit
2) Back of centreboard caring - now modified to form additional kick bar.
3) Rear rudder post - more rounded / blended into floor to improve rigidity
4) Non-Slip - new throughout, more even and regular.
5) Better detailing around hatch locations so any chance of distortion reduced when installed
6) Improved 'hard points' for fixing fastenings throughout
7) Rear now has internal hard points for rear 'carbon bracing bar' when specified or wanted  whether supplied or not so the carbon brace can be neatly installed if later purchased.  Default will be without to keep back open and clean

.... and Numbers start at sail number '800'   

 

Blaze Class is Growing

The Blaze is a fantastic boat and a very high proportion of those who try it end up as converts! It is relatively easy to sail but with sparkling performance especially when it blows when the wings greatly increase the effectiveness of hiking.

Having averaged 70 boats racing over the past two Traveller Series the class is going in the right direction. The Class Association are delighted with the developments.

Is your Blaze "under used"?

The Association encourage anyone with an 'under used' Blaze to advertise it here on the website.
