Maine Cat 38

Torqeedo electric pods
2018 SAIL Best Boats Winner
"If you’re a sailor, if you like multihulls and if you like boats that are truly meant to sail, you owe it to yourself to take a look at the Maine Cat 38."Adam Cort, Sail Magazine


General Design Theory – lightweight – high performance – simple to sail and maintain

Open bridgedeck – better visibility, better looking and great air flow

High Fineness ratio – length to beam ratio close to 12:1 when kept light. 

Flared hulls with protective “shoulder” – drier ride and huge interior volume

Retractable daggerboards and engines – beachable, higher pointing angles and less drag off the wind.  Gunkholers delight – 29” draft

Very simple layout – lightweight interior wood furniture cabinetry, easily added and deleted components to fit requirements of our racers, day-sailors or live-aboards.

Modular build – ship components inexpensively anywhere in the world and do final assembly near home waters.

High speeds – Under sail or power our goal is averaging 10 knots

Auxiliary power – Twin 15 hp lightweight 4-stroke outboards, high thrust, 25" extra long shaft, power trim and tilt.  Easy deck accessibility under port and starboard bench seats for servicing. Added safety from having redundant twin engines. 

General Design Parameters:

Design to be single-handed.  Fun to sail and out-perform all current cruising catamarans on the market.  Comfortable, safe, easy to sail and affordable.

Build the lightest structural components possible by thermo-forming Core-Cell PH core and resin infusing 100% vinyl ester resin in female molds.  Finished boat is 2 hull and deck units, capped bridgedeck platform, rig and roof and you are ready to go sailing in an ocean capable, high performance cat.  We are offering a very simply equipped package to keep the price as affordable as possible.  We offer a host of options you can add yourself in time or we can install at the shop during the initial build.  Our goal is to get you out on the water sailing as economically as possible, before you start adding “stuff” you might be able to live more comfortably without.  Every piece of equipment you add requires maintenance and time taken away from sailing.

Hull Shapes are designed to maximize the interior volume, minimize the waterline beam and keep spray down and off the deck and windscreen.  The nicely radiused chine and “shoulders” we designed provides almost 6 feet at the maximum beam of each hull, yet the waterline maximum beam is only 38” when she is fully loaded to 12,400 lbs.  Our chine is over 12 inches above the DWL and will provide very little resistance or interference for our racer owners and huge additional buoyancy for our loaded-up live aboard cruisers in large seas.

Our approach to the rig design is also going to offer our owners a number of choices to fit their skill level and cruising area.  Our standard rig will be a Selden fixed fractional rig with furling self-tacking jib and fully batten main similar to our MC 41 setup.  Options available will include pole mounted free furling screacher, flat top mainsail, jib boom, and rotating aluminum mast.

Our solution for economical, lightweight and inexpensive auxiliary power which is easy to access, eliminate drag while sailing and avoid lower leg corrosion will be outboard engines.  Our design includes twin 15 hp 4-stroke fuel efficient outboard engines housed in nicely faired twin nacelles port and starboard.  The engines have power tilt and fully retract clear of the water.  

Maine Cat 30 owners have been using outboard auxiliary power since 1996 and it works.


Advantages of Thermoforming the Structural Core in NEW MC 38

 Thermoforming is a process of heating the Core-Cell coring to a point where the mechanical rigidity in the foam is temporarily broken down to a level which makes it flexible, allowing it to be shaped and “formed”. This temporary flexibility is reversed by the cooling of the foam where full mechanical properties are restored.  This method of construction can reduce the weight of the structure by removing any excess resin in the typical PVC core with saw-cuts and also allows a tighter and more accurate fit of the core. This leads to weight savings in core bonding and kerf filling during the build process. 

There are many reasons why thermoforming is a good idea in composite sandwich components. 

• Thermoforming core eliminates the need to have any core cuts or grooves to increase shaping capability, and as a direct result a thermoformed core will not have the additional weight of the resin or adhesive required to fill these grooves.  By eliminating resin in the saw cuts, the Maine Cat 38 has superior cosmetics and no “print” through. 

• Thermoforming allows a tighter fit tolerance to the skins (more time can be taken to ensure the fit is correct). This allows the core to fit with much less filling compound and adhesive – both of which can add significant weight to a component when fitting poorly shaped core. 

• Thermoformed core will demonstrate the exact mechanical properties indicated by the data sheet and product information. The addition of cuts and grooves to the core materials can have large impacts on the mechanical properties which should be accounted for during the design process when specifying core materials in sandwich construction.  The end result is we achieve stronger and lighter composite assemblies that are better engineered for a superior finish product. 

The major disadvantage of thermoforming is the time requirement. The process of thermoforming core is one that requires considerable care and time, making it difficult to integrate into a production build scenario unless additional tooling and operations are available. 

Maine Cat has made this investment in additional tooling and all our thermoforming is performed inside female production molds.  Maine Cat is the only production catamaran builder in the world utilizing Core-Cell thermoforming coupled with vinylester resin infusion. 

         The NEW Maine Cat 38 is stronger, lighter, and a blast to sail.
