![]() That means +/- 3 meters for todays recreational GPS. The early Zeus protoypes had Mil-spec GPS Antenna's providing an accuracy of +/- 1 meter, but they were pricey $$$$. No one would recommend Station Keeping in the immediate proximity of fixed obstructions but it would be great while waiting in a channel for a bridge/fuel dock or over a reef/wreck, etc. |

even 15meters over a wreck jigging short handed is a boon
how much extra for the mil spec? Is it available in our troubled times? |

The high accuracy Mil-spec GPS antenna's were never meant to be an option, just a just a way to showcase the Station Keeping abilities on the protoype models. The main benefits where the accuracy and the refresh rates. Since there are two onboard, it would never be a cost effective option. I can't recall the exact cost of the units, but they were in the ten's of thousands of dollar range.
Some electronics guru could give more detailed info on the cost and availibility to the general public? |

So bottom line do these motors work on length or weight? So EG I have a boat that weighs 65000lb's and is 60ft and I have a boat that weighs 70000lbs thats 45ft, how to chose motor size?, or a 75ft that weighs 110000, and I would like 40kn wot, do you keep adding motors ie 2, 3, 4, just to keep the thrust going, or are they the same as any other motor, 100hp 1kn above normal wot??/ |
