Hey Ben,

Are you using the same mast brand as the sail brand you use??
If so i had terrible experiences with thier rdm mast in waves snapped top and bottom half in the same incident in a two foot wipe out. i then PURCHASED (as not covered by warranty) a new one and it split up the length of the mast where the extension goes in on the first sail.
will not mention the brand but was highly unimpressed.

i recommend using ANY other brand. Hot sails australia have very reasonably priced mast that look to have a similar bend curve to your sails. your free to give mine a go next time.
