Dennis: Many years ago, I used the blue poly tarps for winter storage.

Nobeltec support tells me that some of those are on the "wish list" but cannot give me any estimate of when, if ever, they may be back. Max Pro also seems slower to redraw screens using the C-Map vector charts to me then when I was using Passport vector charts, though I have not done a time comparison.

I would estimate that the uplift in this location is at least 10-15 feet. Most charts in this area carry warnings of such uncharted uplifting. Regards, Mike _____________________________________ Capt. Mike Maurice Tigard Oregon(Near Portland)

Thunder Bay, in Lake Huron, has over 200 wrecks with an estimated 100 more yet to be discovered. The ice cold fresh water keeps them in a remarkable state of preservation and they form a valuable archeological resource. Why so many wrecks? First, the Great Lakes are a weather cauldron with warm air from the plains states meeting cold fronts from Canada.

We can find the exact time and speed for any given station but ther still seem to be a gap when it comes to estimating values in between reference stations.

Carrabelle will have less surge than St Marks, and we are estimating the St Marks boat will have the top of his pilings at about the rub rail level on his boat by midnight when the center makes landfall. Last I heard, he was running long lines from his stern cleats to pilings in adjacent slips to center his boat in the event the surge gets higher.

I also had two boatyards estimates of $20K which involved removing sliding glass door, dinette, galley, AC, floor panels and then port engine to get to leaking tank. I bought a Makita 10-gauge nipper (like electric hole punch) and a Kobalt skilsaw and cut the tank into small enough pieces to remove. 

It is hard to get good time estimates with the OpenSCAD system but I got worst than linear time building trees by insertion of 2500-30000 elements. To minimize stack overflows I have used the tail recursive versions: function treeinsert(tree,value)= (0==len(tree))?

You didn't use a calibrated power reference, so I will estimate. The thermal noise floor is about -174 dBm/Hz. The N210+WBX has a noise figure around 4 dB, so the noise floor is -170 dBm/Hz. You have a 10 MHz bandwidth, but you didn't say how many bins are in your FFT.
