The 49er mast is a critical part of how the boat performs. Correct set up is critical for fast boat handling. This article is intended to show how we arrange the internal halyards and what parts we have found lead to fastest handling.

Firstly below is a diagram to show how the halyards are arranged inside the mast.

The kite halyard runs down the back of the mast keeping clear of the other two halyards.
Both the main and the jib halyard pass in front of the shroud bolt.

To get the halyards correct inside the mast, firstly take the mast apart, and the heel and tip fittings out.
Look up the mast from thejoin towards the tip and check that the halyards are not twisted and that they pass the
correct side of the bolts. If they do not re arrange so that they are and then tape them to the sides of the mast at the join.

Tape them to the side that they exit at the bottom, with the kite halyard in the center by the mast track.

Top Tips Always use Duralac on all bolts. Main and jib halyard are 3mm holt ultra line. Tie the top block to the mast tip with the 3mm ultra line. Pack the mast sheave with the plastic cards that fittings are supplied on. Wash the inside of the mast. Use a lubricant on the mast track

Now align the bottom section in close proximity to the top and tape the halyards to the sides of the bottom section so that they
continue from the top section.

Use a Holt sheave in the mast heel part number HA 4786 8 .The kite halyard rope is 5 mm Marlow excel racing

Looking from the bottom of the bottom section check that the halyards are not twisted, if they are the the next option is to remove the halyards from the bottom section. Pull all three back through the mast so that they all exit out of the end of the bottom section.

With them taped to the join end un twist them and alighn them to the side that they exit. Then use a hooked wire to remove them from the mast and out of there exit points.

Rejoin the mast together and it should all be ready to go.
