You're right Bill.
BIMARE started to make its own mast in the late 2005.
At the beginning of 2006 VectorworksMarine released the following announce (actually on BIMARE's web site):

BIMARE is proud to announce the opening of BIMmasts, its specialized composite division, provided with a 11 m long autoclave, for the manufacturing of masts, beams, booms and poles in carbon pre-pegs.
BIM masts, thanks to its state of the art equipment, highly skilled workforce and unsurpassed know-how matured in over thirteen years, is now ready to offer carbon masts and tubes at the utmost technological level and with the most appropriate bending characteristics.
BIMmasts autoclave delivers 6 bar pressures. Therefore its composite products, made from carbon pre-pegs cured under high heat and pressure feature oustanding weight to strength ratios.
The wise combination of layers of bidirectional carbon, both at 90 and 45 degrees, with biaxial and unidirectional pre-pegs makes possible the fabrication of masts with the selected bending curves.
The automatic control of pressure and temperature together with the accurate lay-up of the carbon fibres allows BIMmasts to produce masts which are exact copies of the prototype choosen for the setup of the sailplan.
All our composite products come from female moulds made from highly polished aluminium extrusions. Therefore our masts, beams and tubes show an excellent finish.

I hope this responds to yr questions.
