Designer Comments
The MAT 1220 is our latest design for a new generation of IRC racers for MAT, emphasising
versatility both in performance profile and configurations.
The premise for the boat is to produce a modern light design that is equally at home offshore
as inshore, taking the rating-friendly features of the successful ?French‘ IRC design type and
combine with slightly lighter displacement. This French style of IRC design combines features
such as medium displacement, greater emphasis on bow overhang, fin keel of moderate
draft, and a number of sail plan tweaks to arrive at a very competitive corrected time
solution inshore over 12knots true, and offshore in most conditions. Because of this
combination of these features it is inherently competitive reaching, and we have been
working on improving the inshore character of the boat in sub-12 for better light airs
windward leeward performance without giving up the ability to get on the step downwind at
a reasonable wind speed. The base rating for the fin keel version with pinhead main is
around 1.155, while with the fin keel and a squaretop it could go up to 1.190.
Building on the deck and styling of the MAT 1070, the large cockpit offer an optimal platform
for high level racing as open space for fun family sailing. The interior can be completed to a
range of fitouts from stripped racing to offshore racing to family racer/cruiser. Working with
engineer Steve Koopman of SDK Structures we have configured the boat to be as versatile as
possible, with the socketed fin attachment allowing easy changes between the standard fin
keel and a deeper bulb keel. The sail plan is built around the lower rated pinhead main, but
for lighter air venues the squaretop main offers a useful increase in sail area. A twin rudder
option is available for more offshore oriented campaigns, and multiple winch choices range
from the base layout to a pedestal driven solution and a powered winch option. Because it is
not an extreme typeform with a medium sized sail plan and reasonable displacement,
stability and draft, we are also working on an ORC optimised configuration.
