Nice looking Adventure.

So tempting…

I'll take it!

Hilarious progression -- and can't blame ya, I wonder if I'da been able to hold out for as long as you did. I already have two adventure hulls.... but that's only enough for myself and one friend!

Hilarious indeed.
I know a guy who had three motorcycles parked in his garage. His wife said, Why do you need three? You only have one ass! I think he sold one and still has two...

This is why I reference my current motorcycle count as "only three for now."  It immediately makes it clear that I'm low on motorcycles and foresee more in the future.

CA Regulations / Re: Fishing on a SUP question
« on: July 12, 2024, 09:10:15 AM »
I don't think I would have ever thought "does this thing need to be reg'd" if I had somehow come into contact with a motorized SUP.  I can't imagine any of my former colleagues would have either.  I certainly wouldn't be registering it, either.

This isn't marketing, it's Ohm's Law.  The current is directly proportional to the voltage.  If voltage goes up, current goes down.  If the device is rated for the current, then all is good. 

I = V / R where I is current, V is voltage, and R is resistance.  The resistance (load) is constant for the device, so as you increase V, I decreases.  Different battery chemistries offer different voltages.

Some of the 16V batteries are lead acid (usually AGM), some are LiFePo4.  AGM cells are ~2 VDC nominal, so they connect 8 in series to attain 16 VDC (your normal 12V battery is simply 6 cells in series).  LiFePo4 cells are ~3.2 VDC nominal, so they connect 5 of them in series to attain 16 VDC.

It comes down to the input voltage ratings of the device(s) you're powering, as you already noted.  Hope that helps!

Since resistance is constant, if voltage goes up, amps go down, but watts stay the same. So, 2 batteries that are rated the same in watt hours will last the same amount of time. But given 2 batteries that have the same Ah (amp hour) rating, the higher voltage one is going to last longer. Does that sound right?

That is correct.

Way to go, dude!!  You're on the home stretch!  Fair winds and following seas, skipper!  Hopefully the perfect winds so you can rest and not have to pedal much.

I solved this problem by getting a newer phone. …

I’ve got an iPhone 12, and it is “water resistant”, but it won’t charge if it detects any moisture in the charging port, which always happens whenever mine gets splashed. Have newer iPhones solved this issue?

That's a feature not an issue.  The phone itself is water resistant meaning the water won't cause damage if it gets inside.  The moisture detection prevents shorts across the connector contacts.  Connectors aren't designed to work in wet environments, so the detection is the best it gets.

For Sale / FREE - compact truck cover
« on: June 20, 2024, 07:37:01 AM »
I recently acquired a 3rd gen Ranger and it came with a cover that I'll never use.  It seems like a good quality cover.  The Ranger is a supercab, so I assume it will fit any compact truck of similar size.

Mr. X is up at 'em early... underway and making way.  He's got a nice group of 4 folks around him keeping him company, too.  Go Mr. X!!

Looks like Forget Me Knot might be out... yesterday was her 2nd day on land.

General Fishing Tips / Re: Elite 5x chirp transducer replacement
« on: June 18, 2024, 02:54:37 PM »
Is this what you need?

Appreciate it and the link (I've looked at before) but I'm a little lost as to what exactly I would need, if that makes sense. For instance, is this Amazon one much worse?

https://www.amazon.com/Lowrance-000-0106-72-Transom-Mount-Skimmer-Transducer/dp/B000KKB5YK/

That one has the wrong connector for your Elite 5x.  You need the 9-pin connector for your fish finder.

What has you lost on what you need?  Is it deciding between the different transducer frequencies?  Something else?

I just checked and it's an Elite 5 chirp (no x) and is 7 pin. I'm mostly lost on the frequencies and their importance as well as whether a given transducer will work with chirp (or is it so commonplace nowadays that they all will)?

My last question was transducer type (skimmer vs bullet vs the super long ones). This will all help in deciding if it's worth buying a new transducer vs buying a whole new unit like the Striker.

I really appreciate everyone's help and input on this! Makes me miss leaving norcal for the sunny south.

The frequencies determine how the transducer performs at various depths and boat speeds.  Here's a snippet from West Marine:

Quote
Fishfinders operate using a single frequency transducer, dual frequencies, multiple frequencies or a broadband CHIRP system. In general, higher frequencies give the finest detail resolution, the least background noise on your screen and the best view from a fast-moving boat, but don’t penetrate as deeply as lower frequencies. Shallow-water inland anglers generally choose higher frequencies of 200kHz, 400kHz or 800kHz. For maximum depth, use lower frequencies. We recommend 200kHz or higher (up to 800kHz) for water depths up to 200' and 80kHz or 50kHz for deeper waters.

CHIRP expands on this a bit...

Quote
The newest style of broadband fishfinders, commonly called by the acronym CHIRP (Compressed High Intensity Radar Pulse) don’t transmit on just one or two frequencies. Instead of transmitting only 200 or 50kHz, for example, CHIRPing devices transmit a signal that sweeps linearly upward (from 40 to 75kHz, 130 to 210kHz, or other frequency ranges).

CHIRP fishfinders transmit less peak power than a conventional fishfinder, but their wide-band, frequency modulated pulses (130-210kHz, for example) can be very long in duration and put 10-50 times more energy into the water. Using digital pattern matching and signal processing, CHIRP devices achieve unprecedented resolution and target detection. Your ability to resolve individual fish, or separate fish from bottom structure, is now a matter of inches, instead of several feet with traditional fishfinders. See individual fish in groups, instead of a single mass.

Depth ranges of 10,000 feet are standard with these broadband devices, which include sounders from all of the major brands. Some of these sounders feature dual-transceivers that allow for simultaneous and independent dual transducer operation, which allows complete customization, as you can CHIRP or dial each transducer into specific frequencies.

CHIRP devices can transmit simultaneously on high and low frequencies. The lower frequency gives greater depth penetration, and it requires less power than a higher frequency signal so it generates less noise. The result is a “whisper into the water” that locates the fish without disturbing them. The higher frequency signal gives even finer detail at shallow to mid-water depths.

So, if CHIRP is important to you, then you want to ensure you get a CHIRP transducer.

As for mount... you will likely want a transom mount.  Those are the ones that are easiest to mount to kayak-specific mounting kits or to glue inside the hull so it will sound through the hull.

7-pin is the legacy connector for Lowrance, so you could buy a 9-pin transducer and then buy a converter cable.  However, 7-pin transducers are still available.  Here's one I found that seems to meet your requirements: https://www.thegpsstore.com/Marine-Electronics/Transducers/Lowrance-HST-WSU-200khz-Transom-Mount-Transducer

Can confirm: scam.  track718.com is commonly used by scammers to provide fake tracking info for scam victims.  There is no actual package being shipped, it just buys the scammer time before the compromised card is reported and shut down.  The provided tracking number doesn't even fit DHL's tracking number format.

Barring a major mishap, it looks like the leading boat will easily finish today. Assuming that is the case, if I read the R2AK website correctly, the sweeper boat (the "Grim Sweeper") will launch on the 21st, and cover 75 miles/day, and once it passes a boat, that boat is required to exit the race.

So far, it looks like Mr. X is averaging about 40NM per day, which is very impressive. If he can continue to average 40NM per day, and all of that is made good towards the finish line (as opposed to, say, tacking back and forth for 40NM, which would result in less than 40NM of actual progress), by my calculation, he'll finish the race about 1 day ahead of the Grim Sweeper...

40 mpd is achievable without problem if weather is ok, if current and wind be favorable to us, we can do even 60 mpd, i waste this whole day on a bay to avoid a strong wind, how about other racers, I cannot check because weak signal

You weren't alone in chasing a lee: most of the other racers in your section of the narrows also took a detour to find a lee.  A few found a marina a little southwest of your location.

Mr. X continues to show his perseverance by ending the day late and starting it early.  The early bird is definitely getting the worm today as he makes good progress past sleepy contenders.  Go Mr. X!

Mr. X has a nice tail wind for the morning.  He's making good 2.4 knots at the moment and he's closed the gap to the back of the pack. 

The one that I find the most amazing is Team Boogie Barge

That one caught my eye, too!  The huge gap the leader, Malolo, had yesterday got me looking into them, too.  That's a fast multi-hull with a team of downright racers.  It's fun to see the contrast between the racers who are keeping time and the casual folks like Mr. X looking only to avoid a DNF.
