During the cross examination of one of the witnesses, he admitted that he based his estimate of the size of the wake solely on the fact that he felt his boat rock when the crewboat first passed the anchored boats but he did not personally observe the wake nor its size.

Have an estimate for how long this will be. Reposition boats to best advantage based on the expected wind after the eye has passed on. Any boat which is sinking, should be sunk to keep it from becoming a battering ram, during the next wind shift. Sink it in shallow water. Remove and put to use any line or fenders from such vessels.

If the owner will sell the vessel for an amount which covers these worst case estimates, I would consider buying the vessel, if I could afford the time for the blister job. But you must recognize one thing, every item on that vessel has been maintained or neglected by this damn captain for an absentee owner. Therefore, everything is suspect.

That aspect can be very hard to estimate accurately. Other owners can often supply this kind of info. (Note: Household appliances are much cheaper than marine stuff and you can buy several for the price of the cost of one marine unit. But, if the replacing is difficult you may wish you had marine stuff.

When Ken hauled my boat for some work he estimated its weight to be in the 70,000 lb range.They were a very labor intensive boat to build and in 1984 O/A discontinued the model and began the Mark-2, a much faster, lighter and simpler vessel to construct. Early boats came with 120 Lehmans. Later models have 671 Detroits, as does mine, and Cummins 555s.

With a helper, I would cut that estimate by 1/3. With two helpers - one half. Working from a homemade float caused some errors requiring extra coats of paint (see bulwarks comment below), but I was sort of happy to have more than the two required coats in those areas.

Be especially sensitive about how you estimate their weight..... ;-) Where to put the ballast? In the lowest part of the boat is generally best. Keep the center of gravity low to maintain boat stability. Virtually anything can be used. Sand bags, lead pigs, water, or anything else.

As I was standing here drinking my coffee and looking out one of our 7 inch picture windows, my thoughts went back to the last storm, where afterwards I was called to give an estimate on some "storm damage".

It gives me a rough estimate of the latency in µs, that I add to 1s (as the system was supposed to begin to stream at 1s).
