What size mast do I need?
As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.
Are Ezzy masts constant curve?
Ezzy masts have a traditional constant curve bend. Our bend curves have not changed since the early 90’s, so older sails will also work well with our masts.
What is the diameter of an RDM mast?
32-33 mm
RDMs have an internal diameter of 32-33 mm. at the base.

What is mast IMCS?
The IMCS formula translates the actual deflection of the mast to what the deflection would be if the mast were 460cm long. IMCS stiffness = (length x length x length) / (460 x 460 x mid-deflection) Top% is the relative deflection of the top (at 3/4 of the mast length).
What is an SDM mast?
SDM stands for Standard Diameter Mast. These windsurf masts are the standard thickness you expect from a windsurf mast.
What is the difference between RDM and SDM mast?
The answer: As their names suggest, the primary difference is that RDM (Reduced Diameter Masts) masts are narrower in diameter than SDM (Standard Diameter Mast) masts. So much so, their narrowness requires a skinny (RDM) base extension and – in some cases – a shim to ensure a tight boom connection.
Can you use RDM mast on SDM sail?
Many modern rotational sails are actually now designed for RDM. SDMs are still compatible, but ultimately the sails are progressing in the direction of RDM and if you want to future-proof your mast purchase it’s a fact worth considering.
How tall is the mast of a galleon?
Right behind is the Main mast, which reaches 120 ft. high and holds two sails. At least 18 people are needed to hoist them: the main yard weighs more than 4,400 pounds.
