SAFETY TIPS

• Every time you sail, be alert to the power of nature and the elements.

• Know your own limits. The mxNext is a high performance boat and

• Plan for emergency conditions. The weather can change very rapidly

SAFETY FIRST

Any body of water, even a small pond, may be dangerous if you do not
treat it with respect.

requires a certain level of knowledge and skill to handle. Carefully read
this manual and get acquainted with all of the boat’s systems on shore
before taking her out on the water.

and even if it’s a nice sunny day when you start out, take appropriate
precautions. Carefully read the section “Emergency Procedures” of this

manual and nd time to practice these procedures so you’ll know what

to do and stay cool in case of a real emergency.

• Always wear your life jacket while sailing.

• Always carry a small paddle on the boat.

• The safest way to learn how to sail the mxNext is by going out on

the water with sailors from your local Yacht Club who can provide

assistance if necessary. If you go sailing alone, always inform someone
else where you will be sailing and what time you plan to come back to
shore.

• Get familiar with your mxNext gradually. Start in a light wind in a well­protected area and go through all the routine maneuvers: tacking,
jibing, spinnaker hoisting and dousing, etc. Try to capsize the boat few
times to develop the skill of righting her.

• Secure yourself properly to the boat. During hiking or rapid acceleration
keep your feet under the hiking strap. Wear non-slip dinghy boots. It
is also a good idea to wear kneepads.

SAFETY TIPS

• If you fall overboard, hold on to the mainsheet or other lines. Try to
avoid holding on to the tiller, especially if the boat is moving at a high
speed, as this may break the tiller or rudder or both.

• Make sure that the boat and all the systems are in working order and
do not show signs of excessive wear and tear. Periodically check all
hardware and running rigging and replace parts if necessary.

• Periodically open the inspection port and check for large amounts of
water that might indicate a leak. It is normal for a small amount of
water to accumulate inside the hull - just be sure you drain the boat

T

SAFETY FIRST

completely through the transom drain plug every time you go sailing.
If a serious hull leak develops, immediately stop using the boat and
contact your local dealer or International MX Composites.

• Check that the inspection port and drain plug are always closed tight
before leaving the shore.

• The hull is constructed with closed cell foam that provides 1,000lbs
(453kg) of buoyancy so there is no danger of your boat sinking.

• The mxNext hull, mast and boom are made of carbon ber, which is
an excellent conductor of electricity. Rigging or sailing your boat near
electrical lines or during a storm with lightening could be extremely
dangerous.

• Contact your local dealer or mxNext representative if you have any

questions about safe mxNext sailing. By putting safety rst, and always

knowing your limits, you will ensure that you have a great and trouble­free time sailing your mxNext

DESIGN FEATURES

The mxNext was developed as the latest generation of high-performance
single-handed skiffs sailed with a combination of mainsail and spinnaker,
an idea that was started two decades ago with the highly successful
mxRay. Both the mxRay and the mxNext were designed and developed by
Vlad Murnikov whose innovative approach to sailboat design continues to
change the way we view fast sailboats.

The design goal was to create a boat that would be challenging and
exhilarating for the most experienced sailors, yet relatively simple and safe
enough for less experienced sailors. The result is a boat that is approachable
for most levels of experience. As long as you know the basics of sailing and
never overestimate your abilities, the mxNext can provide you with one of

the most invigorating sailing experiences you will nd anywhere.

SAIL PLAN

While sailing upwind, the mxNext uses an efcient square-top mainsail

with full length that can be adjusted to a wide range of shapes by using

the vang, cunningham/downhaul and outhaul. The primary mainsail bers

are Technora and the sail is made of a clear membrane which you can see
through to see other boats and obstacles that might be in your way.

The asymmetrical spinnaker has a long luff for more power and a large

head area that keeps it stable even in a light breeze. It’s easily deployed using
a reverse 3:1 purchase which requires only a 5-foot pull to set the spinnaker.
The tack line is connected to the halyard so the same pull that raises the
spinnaker also pulls the tack out to the bow of the boat.

To lower the spinnaker you simply uncleat the halyard, pull the retrieval line
and the sail folds up for easy storage in the spinnaker sock. The retrieval line
is led through a lower patch on the sail and attached to the upper patch. When
the retrieval line is pulled the spinnaker folds up in three portions and stows
neatly inside the spinnaker sock. Only the three corners are left outside the

sock, ready for the next hoist.

HULL SHAPE

The hull shape is a development of the mxRay as well as SpeedDream,

a new innovative design concept that relies on efciency over power

for high performance. The mxNext hull is very sleek and narrow on
the waterline. This is part of the secret of the boat’s speed. A narrow
waterline reduces wetted surface which in turn reduces drag translating
into speed. The cross sections of the hull are fairly deep and rounded

forward, gradually shifting to an elliptical shape that gets flatter as you

move aft. This is a perfect planing hull.

The aft-swept wave piercing bow slices effortlessly through waves at
any point of sail. There is plenty of reserve buoyancy in the forward hull
sections so that if you surf down a wave and the bow starts to become
submerged, the buoyancy immediately kicks in and lifts the bow right
out of the water. There is almost zero chance of pitchpoling.

The elegant hiking wings are there to allow you to get your weight as
far outboard as possible. They are also ergonomically designed so that
you can hike comfortably for long periods of time. The principal control
lines; the mainsheet, vang and cunningham are all within easy reach of
a full-hiking position.
