The Blaze is suitable for a wide range of helm weights, typically 11 to 16 stone. However there are many outside this wight range, in both directions, who have done very well at National and other races.
The Blaze is suitable for all except the smallest inland waters in Britain as well as estuary and sheltered open water around the coast.
The Blaze excels in force 4-5 winds and is sailable at higher winds when helms from other classes are more often viewing from the shore! The boat sails well in medium to strong winds when it can easily plane, upwind as well as downwind, due to the flat wide hull with minimum rocker.
Around force 2 it is probably least competitive against other classes but on a 'drifter' day it can often do surprisingly well due to the relatively large sail area towards the top of the mast.
