My boat before the Engine upgrade (now two suzies 250Hp, total 500hp).
Imported it from the USA 3 years ago, a used 1998 boat, with the new motors it will run between 50/60Mph top speed and cruising speed will be 40Mph.
Our regular fishing ground are around 40 miles away from Luanda and if fish is not bitting on south you must go north to save the day (another 40 miles..)
Sometimes blue water is beyond 30/40 miles West of Luanda.
The last season Angolan Billfish champion team "Tubaroes" have a 35 foot CC, 900 HP (3x300HP Suzies) Triton boat.
Faster, here, means more time fishing and in the end of the day can make the difference.
