Cost of New Mast and Rigging?

[Sand crab]

Many mono masts are keel stepped so they go all the way through the boat to the keel but just about all cat masts are deck stepped. That mono mast might have quite a bit of it's length buried.

For instance Lagoon states that their 450S has 73' 3" "mast height clearance". A 70' mast on the Leopard would make it almost 80' above the water!!!!
You need to contact Leopard.

You would be closer to estimate by the pound vs foot.

Look at boat displacement and judge that way?

Here are some prices for similar boats including a Lagoon 450.
