Ballast - delta planform - 6 Metre and A Class. Ballast bulb with wider delta planform, to suit 6M and A Class, cast in sand state. Same design as that used on the SWORD, A Class, of Bantock over recent seasons. Choice of 8, 9, 10 or 11 kg cast weight. Higher weights by arrangement.

Use item INS-080 to make a secure connection for the ballast to the fin that allows the ballast to be removed.

This design has a lower centre of gravity than the earlier version and a wider span at the trailing edge. The fore and aft sections are aligned at progressively different angles to reduce drag both when the boat is upright and when sailing to windward. The shaping also works to keep the boat well balanced when sailing to windward at larger heel angles. The effect is as if the boat has additional stability and steadiness when well heeled. Induced drag is reduced by virtue of the larger span. Experience with the SWORD indicate that any performance loss in light airs is not very significant compared with the benefits elsewhere.

Self adhesive coarse abrasive paper bonded to 3 mm ply to make a 'file' is excellent for fairing the surface after using a Surform blade. The 40, 50 and 60 grades followed by 100 grade are particularly useful. See SAILSetc product WD-COARSE.
