There exist two versions of the GT-31, hardware V1.0 and V1.1. The V1.1 hardware uses a ultra-low power version of the Sirfstar III chipset and lasts for even 40 instead of 30 hrs on a single charge. Units with serial number from 832001650 are V1.1. Those before are V1.0. There is way other than the serial number to distinquish.
Note that the firmware version may be 1.1 while the hardware is 1.0, which probably confused my vendor, as he told me that mine was V1.1, which it wasn't.
The unit has a low power mode which lasts even longer, up to 40-60 hrs. Locosys doesn't recommend using this unless lower position accuracy is acceptable. I haven't tested this low power mode yet.
so the last paragraph states that you may lose out on position accuracy on low power mode. that suggests to me that it's no good for sailing, but i'll happily defer to anyone out there who's expertise goes beyond google...
