As a general rule, boats go faster to windward with their mast raked aft and faster downwind with the masts raked forward. In light winds the mast is set in its most forward raked position and progressively raked further aft as the wind strength increases.
Raking the mast also alters the rake of the jib, opening the jib slot and depowering the rig.
On a Cadet, correctly adjusting your mast rake for the conditions can greatly improve your boats performance.
To measure and adjust your mast rake:
- Attach the jib and load the rig to 15 on the rig tension gauge. Measure this at shoulder height on the shroud.
- Tie a tape measure onto the main halyard.
- Pull up the halyard until the tape reads 4140mm on top of the gooseneck black band.
- Cleat and re check
- Measure mast rake at the back of the boat by pulling the tape measure down to the transom.
- To adjust mast rake you will need to release the jib and adjust the shroud plates and repeat.
It’s a good idea to write down your settings so can adjust your mast rake easily as conditions change.
The ideal mast rake settings are as follows:
|Light Winds||Light Winds||Medium Winds||Medium Winds||Heavy Winds||Heavy Winds|
|0-5 knots||0-5 knots||5-15 knots||5-15 knots||15-30 knots||15-30 knots|
|Mast Rake (mm)||5000/5050||500/5050||4980/5000||4980/5000||4960/4980||4960/4980|
