    PFD advice

    I have two Deckvests. The first one I bought was for racing/cruising on the Chesapeake and has the Pro Sensor. Never had an unexpected activation despite being in some very wet races. When I started to race offshore (bow) I bought the second Deckvest with the Hammar because I wanted the extra peace of mind that it wouldn't go off if/when I get creamed by a wave from behind as I'm on all fours at the bow dealing with a sail change in big seas...

    That's correct, the Ocean Signal MOB1 is AIS and DSC only. I carry the MOB1 in my Deckvest along with a hand-held VHF with GPS & DSC and the PLB1. For the MOB1 to work properly, the antenna would need to be out of the water long enough to get a signal out. Given the sea state, it's possilbe its range was significantly reduced. If it is properly integrated onto the bladder, it will automatically start once the bladder inflates. The Deckvest also has an integrated pylon strobe but it's rather small. The Deckvest bladder is a very bright yellow-green.

    PLB with AIS

    Spinlock has a partnership with the Ocean Signal guys where you can buy a Deckvest with the RescueMe MOB1 installed on the manual inflation tube such that it automatically starts transmitting after inflation. First ping goes out to all AIS receivers within 15 seconds and then automatically for minimum 24 hours. It also broadcasts over DSC. If your chart plotter doesn't alarm on an AIS MOB signal, your ship's VHF/DSC will alarm on the DSC distress call. You can also buy the MOB1 separately and install it on the Deckvest inflation tube yourself. I plan on getting the MOB1 this Spring for use in this year's A2B.

    iRegatta - anyone use it, recommendations?

    Thanks for the info, Allen, sounds promising. I'll download StartLine and give it a go. Best of luck on your new project.

    iRegatta - anyone use it, recommendations?

    The guy I race with is really into iRegatta but it tends to be more of a distraction to him, he spends a lot of time with his head in the iPad instead of steering the proper course. I have yet to see any performance benefit in our race results. StartLine sounds intriguing...I'm using the Sony Xperia Z3 Tablet Compact as my nav plotter/tactician processor (cobbled together a nice articulated RAM mount for it), is it worth learning to use it if the only offboard data I can provide is a bluetooth GPS signal?

    The resin and the core burn. Rather easily in fact. When I was building composite airplanes years ago, we did some preliminary firewall suitability testing using Kevlar/Graphite facesheets and different weight honeycomb cores coated with various heat protection measures. If I remember correctly, the firewall had to survive a 1 inch spot flame at 2000 deg for 15 minutes (or something like that) so we calibrated a cutting torch to the temperature and fired away. We never made the time limit because the resins and honeycomb cores would smolder then ignite resulting in total loss of structural integrity.
