Details

Maximum size is 700 mm length x 280 mm chord at top x 75 mm chord at bottom, fitted with internal structure, allows choice of size and lay-up to suit application. The surface is slightly irregular due to post curing of the whole fin after bonding, leading and trailing edges require finishing. Guide price is for a fin sized for SWORD.

Use with fin box/mast tube moulding, ref.350G. For a secure removable connection to the ballast and hull use fin insert, ref. INS-080.

Made from metal moulds cut to a section that is excellent for the intended application. The skins are bonded in our usual fashion to a corrugated core that guarantees the section shape and maximises the stiffness. All carbon laminate. The surface of the fin may have fine air bubbles and other minor faults created during the manufacturing process. We try to minimise these but it is impossible to avoid them completely. Fins that are un-acceptable in our opinion are offered on our GOODBUYS list. For best performance the bubbles should be filled flush with polyester of epoxy filler, abraded, lightly sprayed with primer and re-abraded with 1200 grade wet and dry abrasive paper.

Choose the chord length from a maximum of 280 mm at the top to a minimum of 75 at the tip. The leading edge tapers at 16 degrees to the trailing edge. Price will depend on the size of fin required. The mould is long enough to make a fin 700 long with a chord of 280 mm at the top and 75 mm at the bottom. Fins moulded in the central section will suit light displacement boats in the A Class. Heavier boats can use a fin moulded in the upper part. 1/12 th ACC yachts would use a fin moulded in the lower section. There may be other applications too. This moulding has a flange at the leading and trailing edge which needs shaping before use. We choose a lay up to give an optimum trade off between weight and stiffness and a fin that is far stiffer than any alternative for its weight.
