When I got my first look at Manta, a custom built Tim Mumby designed 47′ Power Catmaran, I could hardly believe my eyes. Well known for his sailing catamarans, this is the first and so far only Mumby power cat in existence. She is the ultimate expression of a world class cruising yacht, with a range over 3,000 nautical miles on 1300 liters of fuel. Add to that the sloop rig on a short 6 meter aluminum tabernacle mast and that range goes closer to 3500 miles.
Constructed from the ground up over a 2 year period in the Philippines by the current owner, with over 40 years and 3 circumnavigations of sailing experience himself. She was launched in 2020 then motorsailed up to Dutch Harbor, then down the west coast to her current location here in La Paz, Mexico. Over 2,800 watts of solar power, she is completely set up for off grid long distance voyaging. Every detail was designed and built with an eye toward ease of maintenance and courageous practicality. She comes with every spare part you can think of and is ready to take you on your own circumnavigation. We have tons of photos demonstrating how this work of art came into existence. Just drop us an email and we’ll send you a link. You have to check this one out.
Currently located right here in the heart of paradise and home to some of the world’s most renowned cruising grounds, La Paz, Mexico, the gateway to the Sea of Cortez. Dozens of beautiful anchorages, many with white sand beaches and all with crystal clear warm waters teaming with exotic sea life. Let the experts in yacht ownership here in the Mexico, show you how easy it is to begin your cruising dreams today.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
