huh? ever heard of minimum bare steerage speed?
wala cguro ka kasakay ug mga barko nga kun mag 8 knots below dili na ma-steady ang heading.
Ang maneuvering speed sa akong mga barko nga mga nasakyan is 14 knots man at 40RPM
So 15 knots kusug na kaayo on a narrow channel?
parehas man gyud ta wala nkasakay ug inter-island then perhaps nakabiyahe
naka sa mga inland waters sa America say Savannah River on a container ship perhaps?
Wala ka kasab-i sa Pilot ug nangayo nalang siya ug additional RPM if your vessel can't provide the 14 knots he requested sa maneuvering full.
15 knots kusug ra kaayo on narrow channel?
nakabiyahe ka sa Ningbo where currents can go as strong as 9 knots?
15 knots kusug ra kaayo on a narrow channel?
Nakabiyahi ka sa Ho Chi Minh?
The approach is narrow as narrow can get.
If wala paka naka biyahe sa Ho Chi Minh or kita sa charts diha,
I'll be happy to provide you a screenshot from my Transas Chart Collection.
(dili na nimo makita sa OPenCpn CM 93v2 charts).
Wala ka kuyapi pag-ingon sa Pilot to go full sea speed - full sea speed on a very narrow river (edit: and parang bituka ng manok as an AB described it) on a container ship at that?
I can go on but anyway ang akong punto is nganong naka-ingon man ka nga 15 knots is kusug ra kaayo on a narrow channel?
Pilot ka? If you are, then i must relent and crawl back under my rock.
Pero i doubt nga Pilot ka or an officer-of-the watch at the very least.
Kay if you have stand watch maski 4 hours lang samtang ang imong barko is navigating on a "narrow channel"
you should have known nga "safe speed" on a narrow channel is relative.
Daghan factors involved, some of which i've already mentioned - minimum bare steerage speed, current and Pilot's discretion.
Needless to say there are vessels that must maintain an ideal safe speed of 15 knots in a narrow channel
ang mo slow down lang where there are very shallow areas to reduce the squat.
I can go on discussing squat if you like
