Have I got the trim correct on my open aluminum boat?

I wonder if it is safe to boat without being able to see in front of
you?

It does conflict with the responsibility to keep a proper lookout. I
looked at some pix of the Emma Mxxxxx the worlds largest boxboat.
Two hundred fifty feet from the water to the deck. Hide another ship,
not just a boat, under those bows.

Ok, I'll plead ignorance.

What is a box boat? I'm familiar with the J series "box" boat (I
think they call them cracker box) racers, but I have no clue what a
box boat is.

Especially one that is 250 feet high from water line to deck. :)

Container ship?

250 feet high?

That doesn't sound like much, but trust me - that's high.

Here's one 207 feet. Not sure if that's from the bottom on the keel or
the
waterline. Probably from the keel.

Depth is deck-to-keel which in this case is 30 metres or 98 ft
according to the specs. There are 8 stories to the super structure
including the bridge which, if normal corridor height is followed is
just shy of 60 feet which make it in total, 162 feet in height.

That's a little short of 250 feet or 207 feet for that matter.



Where does the 207 foot spec come from?


The Emma Maersk is over 1300 feet long and displaces 170 000 tons.
Draft is 30 M. I can't find the web site that had the height water to
deck. I am not sure what they mean by depth at some of these websites.
Draft is waterline to keel, The depth of the hole in the water it
makes. The waterline to deck dimension is commonly called freeboard.
For completeness there is maximum height, the lowest bridge it can get
under. Sometimes they call that airdraft. From the waterline, not the
keel.

My boat is 22 foot and if it was in proportion to a ship 1300 by 250,
would have a freeboard of somewhat over 4 feet, and that is in the
ball park. I saw a picture, and the 250 figure didn't trip the BS
detector. What perhaps should have, is how do you unload it? Of
course, if it only uses two ports that's only 4 or 6 cranes that would
have to have that high.
