How do I choose a windsurf mast?
Determine your sail’s ideal mast length. Common mast sizes are 370, 400, 430 and 460 centimeters. If your sail doesn’t offer an ideal mast listing, look for a “Luff” measurement. Typically, you want a mast that’s length is closest to your sail’s luff length, though exceptions exist.
What diameter is a windsurfer mast?
Standard Diameter Masts (SDMs) are mostly around 48-mm. wide (internal) at the base and the lower tube that will fit various lengths of mast extension (dependent on how fast they taper towards the top section).
What is mast IMCS?
IMCS is a measure for the average stiffness of the mast. The ‘I’ stands for ‘indexed’. That means you can use the IMCS to compare the stiffness of 2 masts of different lengths. The IMCS formula translates the actual deflection of the mast to what the deflection would be if the mast were 460cm long.
What volume windsurf board should I ride?
The most important thing to look for when buying your first windsurf board is the board’s volume. You need one litre of volume for every kilogram you weigh PLUS between 50 and 100 litres extra. So if you weigh 75Kg, your first board should ideally have between 125 and 175 litres of volume.
What should I look for in a windsurfer?
Buying a new windsurf board
- Where are you going to sail? This is the first question you need to ask yourself.
- Volume. As mentioned before, the wind conditions will determine the size of the board.
- Board type. Again, this is related to where you will sail.
- Weight.
- Sail compatibility.
- Dings.
- Cracks.
- Weight.
Whats the difference between RDM and SDM mast?
WHAT’S THE DIFFERENCE BETWEEN SDM AND RDM MASTS? The answer: The primary difference is RDMs (Reduced Diameter Masts) are narrower in diameter than SDMs (Standard Diameter Masts). So much so, their narrowness requires a skinny (RDM) base extension.
What is an RDM mast?
Reduced Diameter Masts (RDM’s), are small diameter masts that are built for maximum durability and strength. We offer RDM masts from PowerEx, Ezzy, GT, Neil Pryde, Severne and Chinook. They are the favored mast for wave and high wind sailing conditions.
What is a freewave board?
Freewave, or freestyle-waves, boards are among the most sought products by non-professional windsurfers, as they are the ones that allow to cover, especially in intermediate volumes, a wide range of conditions.
How many Litres should my windsurf board be?
What is an SDM windsurf mast?
Standard Diameter Masts (SDM’s) They have an inner diameter of 1.9″ (48mm), require use of standard diameter extension, are 2-piece masts and available in 340 – 520 cm lengths. SDM masts come in 2 construction types: Epoxy or Carbon.
What does RDM mean in windsurfing?
Reduced Diameter Masts
Reduced Diameter Masts (RDM’s) They are the favored mast for wave and high wind sailing conditions. They have an inner diameter of 1.5″ (38mm), are 2-piece masts, require use of skinny extensions and available in 310 – 490 cm lengths. Rdm masts come in 2 construction types: Epoxy or Carbon.
What is the difference between a 1/4 and 3/4 mast?
The difference in deflection between the 3/4 mark and the 1/4 mark is represented on a scale of 6 (hard/stiff top) to 20 (soft top). A mast is considered to be constant curve when the 1/4 and 3/4 points have a similar deflection. When the 3/4 point deflects much more than the 1/4 point a mast os considered to be flexi top (16-20).
When is a mast considered to be flexi top?
A mast is considered to be constant curve when the 1/4 and 3/4 points have a similar deflection. When the 3/4 point deflects much more than the 1/4 point a mast os considered to be flexi top (16-20).
What is the difference between mast stiffness and mast curvature?
Whereas the stiffness refers to how the flex of the top and the bottom half differ, the IMCS (Indexed Mast Check System) measures how much the mast deflects overall. To measure the mast curvature a mast is rested at the ends and then has a 30kg weight hung at the centre.
How do you measure a boat mast?
Then the mast is measured at the 1/4 point (lower half) and at the 3/4 point (upper half). The mast will bend slightly differently in the lower half than in the upper half, mostly due to the smaller diameter towards the top.
