Ballast, bulb - 0.5 kg. Ballast bulb, to suit 65 Class, RG65, Nano and similar sized boats, with slot, cast in precision mould, cast state.

The weight is 500-525 grams after smoothing.

A brass rod runs down the centreline to help prevent the ends from being damaged. The ballast is cast from an alloy of lead and antimony to increase stiffness. The casting process can result in cavities in the surface and inside the casting itself especially at the fine ends of the ballast. Expect to fill these cavities with epoxy or polyester filler to create a fair surface before preparing to spray the ballast. We recommend a convex Surform blade, held in the hands, to reduce significant weight from a ballast and varying grades of file to produce a fair surface before moving onto to varying grades of grit paper, ref. WD-COARSE.
