There seems to be significant discussion on "un-charted" obstacles and how best to avoid them. It seems to me that if this is of paramount importance for the safety of boat, crew, and guests, then the 3-D Forward Looking Sonar product from FarSounder would be the best product available today to prevent "contacts-of-the-wrong-kind". (http://www.farsounder.com <http://www.farsounder.com/> ) The product is expensive but, so is the boat and what price does one put on the lives of crew and guests. They are also working with the military/governments to identify underwater security issues. The demo on their web site runs on MS Vista but I found that when done using the demo I had to do a system restore to get the computer working correctly again. Maybe this was just me but it was not a major problem, just an inconvenience. I believe they mention that the demo is supposed to work on Windows XP. Comments welcome, Thanks John

I couldn't find any description of pricing... any idea? Also, it claims to use a kilowatt of power and operates at the same frequency as dolphins. I suppose that means you'll temporarily deafen them, at least when passing closely. I rather doubt that dolphins radiate a kilowatt of power in their clicks.

Prices I've seen on the FS ranges from $70,000 - $90,000 installed. Ken W has a blog post that talks about his basic research into the feasibility of installing it: http://www.kensblog.com/aspx/blob2/blobpage.aspx?msgid=463430&beid=18146 For those of you on the Nordhavn Dreamers list, there are photos of a FS installation in a N68 (I think) in the Photos section. /afb On Thu, Jun 11, 2009 at 5:55 PM, John Marshall <johnamar1101@gmail.com>wrote: > I couldn't find any description of pricing... any idea? > > Also, it claims to use a kilowatt of power and operates at the same > frequency as dolphins.
