Mast Extensions size

[pepevo_mx]

Does anyone know why the mast extensions come in multiple sizes ?

They are 10, 25 and 48 cm in length.

Which one is best and why?

Thanks

Look at the luff length requirement for your sails, and subtract the length of your mast, and thats how much extension you will need.

i.e. with a 48cm you could extend a 490 mast to around 535cm for say an 8.0, but if you had a 510 you would only need 25cm of extension. That would be more ideal but theres nothing wrong with using a lot of extension.

What you want to avoid is using a long extension when you dont need it, like sticking a 48cm extension all the way into a 460cm mast to only add 4cm will add way too much stiffness and will make proper downhauling difficult if not impossible. So buy the shortest one you need.
