I own a Maramu (#354, 1984).
The boat is equipped with traditional musts and with the 63 hp Perkins. I have some questions regarding the performances by engine and under sails.
1- what is the typical Maramu dead angle in the up-wind going? (considering a wind speed of 12 kn and sails in good conditions)
2- what is the cruising speed that the 63 hp Perkins can provide continuously for a long trip?
3- what are the features of the original propeller?
Many thanks for your comments.
Greetings and fair wind to all.
