So why do people buy cruising catamarans if monohulls in
the same price range are just as spacious and can go just
as fast ?

1. Shallower draft
2. They can be parked on the beach
3. They don't sink as easily
4. They don't roll like monohulls
5. ???

We raced our Schock 35 for many years and often there

tend to agree that in general a large monohull will be as
fast if not faster than a cruising cat.

There are a number of errors in logic in the above post.

People buy cruising catamarans because they are better than cruising monos,
albeit generally more expensive.

Firstly let me make a comment about speed. In this perennial argument there
always seems to be the anecdotal statement that someone in a mono somewhere
beat a multi around a course and that means that multis aren't faster.

Let me point out the reality. Cruising multis (of similar size) are slower
than racing monos. Racing multis are faster than cruising monos. Racing
multis are faster than racing monos (clearly evident from all the long
distant records and also from the America's cup farce in NZ between the huge
mono and the multi half its size where the cat annihilated the mono to
windward and held back off the the breeze so as not to jeopardize the
subsequent court case). Cruising multis are faster than cruising monos- but
not by much as both tend to be overloaded and the evidence that I have seen
suggests about a 10% difference.

Shallow draft is great.

Movement under sail is arguable as multis have a sharper motion but the lack
of heel is a big plus. On my cruising cat we never had a glass spill even in
40- 50 knots ( though I admit we weren't beating into it!).

Non-sinkability is a huge safety plus and forgotten by the mono brigade.
Here in Oz in the last 25-30 years there have been no deaths from multi
capsizes but well over 200 deaths from mono sinkings. Multis here are
popular and account for 25-30% of boats cruising, so it's not a statistical
error. Clearly capsize is not nearly as dangerous as sinking. Better
upside-down on the surface than right way up on the bottom.

Beaching is not that common.

At anchor they can behave poorly, especially in wind against tide
situations.

In cold climates they are harder to heat and all the deck space is not much
use- the converse is true in the tropics.

The spaciousness is great if a cat is large enough so that the bridgedeck is
a lounge area. This means that the staterooms are separate, the shower/heads
are separate, and the whole setup is more like a house. Monos are more like
a dormitory.

If, given the choice, I would certainly choose a large multi over a large
mono for cruising.
