Actually, Dooley works midnight to eight; you're on an overlap shift, noon to eight. Thus Brian is the one who is probably getting some food somewhere, and Dooley has managed to get three or four hours of sleep. It doesn't much matter, as Donald wants all hands--it's only a matter of who can get to the crow's nest first (and you can't, because you're afraid of heights). Brian is easily found and sent that direction (and the word "whirlpool" has him running).
When you get back to Donald, the deck is bustling.
Your telescopic vision comes in for an instant, and then you lose it; you close your eyes, refocus your mind, and try again, and you've got the vision.
You can see the spot where the water seems to fall away, and the current beyond that moving swiftly in the opposite direction; you can't actually see well enough to identify it as a whirlpool from here, because you're not high enough to see down into it. However, it is close enough that the ship is already in the pull of the current.
Donald is looking through the spyglass, and then looking up at Brian (whom you can see remarkably well when you glance that direction), and waving his arms for the pilot to see.
"The objective," he says, "is to plot a course that will get us past the whirlpool. We're already in its current, and if we turn too sharply away from it it will suck us in; but if we get too close, we'll wind up going down it. Thus we need to get full sail and take advantage of the current to drive us past it, and hope we have enough velocity on the other side to continue beyond it. The best choice is to go around it to the point that we have the wind directly behind us and let it drive us forward.
"Watch the angles; notice the force of the current and the direction of the wind. You can watch and learn for the moment--but if they yell for help on the lines, you'll have to get down there and pull."
The sails are all full open, the lateen sails catching the wind at a bit of an angle.
Your telescopc vision lasts five minutes and then returns to normal; you realize that you are a lot closer to the hole in the water than you were five minutes ago.
