Micro Magic setup page.

This page has been set up to give measurements from some of our faster MM's. In this way, newer members will be able to set their boats up to a basic workable setting which can easily be repeated from week to week. With permission of owners, settings will be measured from boats which have performed well on the day so we can build up data for A, B, & C rigs over a range of wind strengths.

Measurements so far are listed in the table below. They will be amended and added to as further measurements are made.

How measurements were made.

Measurements were made using a business sized piece of cardboard with a millimetre scale. The pictures below illustrate the process.

       
 
Slot between end of jib boom and mast.
Zero in line with mast centre.
 
Curve in the foot of the sail is measured by holding the card up against the sail and pushing until the sail is reasonably taught.
 
To measure twist in jib hold the boom down to keep the topping lift tight then measure the distance from sail to the lift line.
 
 


Measure twist in the mail sail in the same way as the jib but holding the main boom up to get tension on the vang and in line with mast and backstay. Then measure distance from sail to backstay by eye.

191 B 50 25 20 20 35 60 Boat was keeping up with A rigs. High end A winds.

NOTE Data for MM191 is included in the table for trial purposes.

Futher tips from the experts depending on conditions.

1. Curve in foot of both sails can be increased a little in choppy conditions to drive the boat over the waves rather than through.
2.
3.
