Below is a link to download a PDF format document of a summary of marine-related theft stats from the Florida Fish and Wildlife Comission. This is public info. I do not think this is 100% accurate as not necessarly every LE agency might be actively reporting to the FWC. The bulk likely are however. It gives a pretty good indication of trends - and they are not good....

FWC Stats

A few summary tidbits from the PDF file you can download at the link above:

Reported thefts - 2nd quarter (April, May, June) comparison year-to-year:

2005 = 472
2006 = 614
2007 = 784*

* 22% increase in 2007 compared to 2nd quarter 2006 Vessels account for 492 of these reports.

Estimated projected thefts to be reported in 3rd quarter 2007 = 823

Make sure to read the footnotes in the actual document. This includes marine-related theft reports - including parts not necessarily the total vessel. NOT included is electronics external to the propulsion system such as GPS units, radar, radios, depth finders.

Jet-ski thefts are down 6% for the year - so far
Thefts of vessels 26-39' in length up 6% for the year so far

Thefts of boats 26-39' in length:
2007 (so far) = 13% of total thefts
2006 = 7% of total thefts
2005 = 6% of total thefts
Due to the $$ value of boats in this size range be sure these repesent a far larger % of the total $$ value of marine-related thefts - the above is just the number of theft reports.

Problem areas from January 1, 2007 through July 31, 2007:
County and # of thefts:
St. Lucie = 2
Martin = 2
Palm Beach = 6
Broward = 7
Monroe = 8
Collier = 3
Lee = 5
Charlotte = 0
Pinellas = 8
Miami-Dade = 68


Top 5 most stolen boat makes 26-39' range:
#5 = Avanti
#4 = Pro-Line (Express Series)
#3 = Hydra-Sports (Vector Series)
#2 = Contender
#1 = Wellcraft (Scarab)

MY own personal opinion is that Renegade brand will make this list soon - there are about 7 reports of this make stolen in So. Florida (Miami) in the last month or so alone.
