    Need a good idea

    Bonding epoxy to aluminum can be problematic due to how fast the alu oxidises. One way around this is to paint the alu with epoxy, then sand the alu while the epoxy is still wet. Keeps the oxygen off of the active surface and makes a good bond.

    Georgia asked me about that, it was full of beer. Fell off the back of a Magic 25, not the one that lost its rig though, they kept their priorities straight and salvaged the rum.

     

    I saw the bag float away, but seeing as how we were rigging up with coastguard at the time to pull the boat back upright it wasn't high on our priority list either

    Nope, only one bluetooth connection allowed. And their app doesn't know which way the boat is pointing, there is a calibration mark on the sensor for pointing of towards the bow.

    Hence why I want the NMEA sentences so my daylight viewable chart plotter can actually use the information properly

    This is a bit of the thought experiment, as I probablly have better things to spend a load of cash on, than try to get a reliable VMG to windward on my insruments, but we can all dream

     

    Current setup - 8.5 Multihull, with rotating mast.

    No mast head gear, no paddle wheel, just raymarine A60 charplotter on NEMA 2000

     

    What I am thinking is using something like calypso cups (or the vavuud) as masthead gear, then their bluetooth to NEMA0183 gateway, then a 0183 to 2000 converter.

    I like the look of these as they incorporate a compass into the mast gear, so the rotation of the mast is irelevent. (sailtimer did something similar, but I've not heard great things about them)

    However, bluetooth to 0183 to 200 seems like a lot of interfaces and sounds like a recipe for multiple places for problems to hide.

     

    The alternative is to go with a more traditional masthead gear, then add something onto the mast to measure rotation, but even the cheap gear out there for this seems madly expensive, and is going to need some very careful calibration.

     

    Any other suggestions on how to get decent wind information on a rotating mast?

    Looks like Epsom salts has just had a price drop. The whole dry berth sailing idea is intriguing........

    I don't think the price includes the dock

    No, but we are basically saying that what's in the cat 3 regulations is generally considered appropriate today for a responsible skipper doing coastal sailing in the gulf.

     

    Sure there are a few minor oddities, but nothing significant that you can point to as an active barrier to racing.
