They are the only moth in the family Saturniidae known to be polyandrous. This is likely because C. promethea is the only moth that is both diurnal (males) and nocturnal (females). This allows for egg laying and mating to occur at different times of day, so …

C-Tech spars (Moth mast, Moth boom, Moth battens, Moth tube sets), have the highest possible stiffness and strength to weight ratios and are produced to exacting standards with consistent bend curves. This is achieved by a combination of fibre selection and placement. The fibres are all high modulus prepreg carbon fibre.

Over the past two years, C-Tech has introduced its groundbreaking 05 Range of Moth Masts, setting new standards for performance and elevating the overall sailing experience for male and female sailors in this ever-evolving class. A standout feature of the 05Range is its smaller diameter, achieved by transitioning from a 37mm to a 33.68mm mandrel.

Creatonotos gangis, the Baphomet moth, [2][3] is a species of arctiine moth in South East Asia and Australia. It was described by Carl Linnaeus in his 1763 Centuria Insectorum. It is often listed as a synonym of Creatonotos interrupta, [4] but the identity is unclear.

2025年1月31日 · C-Tech is dedicated to making the Moth class more inclusive by developing equipment that caters to a broader range of sailors, including female and lighter sailors. The introduction of the 05F mast, specifically designed for sailors weighing around 60-70kg, has been a significant step toward this goal.

<math.h> 是 C 标准库中的一个头文件，包含了大量用于数学运算的函数和宏。 这些函数和宏提供了基本的算术运算、三角函数、指数函数、对数函数、幂函数、舍入函数等。

Ceratomia catalpae, the catalpa sphinx, is a hawk moth of the family Sphingidae. The species was first described by Jean Baptiste Boisduval in 1875. Other common names are the Catawba worm, or Catalpa sphinx. [2][3] Ceratomia catalpae is a native of southeastern North America and can be located on catalpa trees that grow within this region.

Mast C-Tech has a range of Moth masts that can be used with all current rig and manufacturer configurations to suit all sailor weights. Standard specifications can be tweaked for individual preferences. The 04 mast range is effectively the 03 range with the reinforcing laminates shifted approximately 400mm further up the mast.
