Quick question folks. Does anyone know the retrieval rate of a full 113h and a full 114h in inches per revolution!

Thanks
Bob

Depends on the gear ratio and I don't know without just measuring the line take up.

BMITCH

Gear ratios are both BP SS gears.

Measure the diameter of your spool, lets use 100mm as an example x Pi x rpm. This will give you your retrieve rate. eg 0.1m x 3.146 x 30rpm = 9.43m/min. 9.43 x 3.28 = 30.93 feet per minute divide by 12 to get inches per minute (2.57). This is just an example you need to know your spool diameter & rpm to get the right answer.

According to Penn's website and using the new Chinese reels as a guideline, the Special Senators have the following inches per crank retrieval:

113H 3.3:1 RATIO= 26" PER TURN
114H 2.9:1 RATIO=28" PER TURN

using a simple ratio formula I came up with this:

113H 4.0:1 RATIO=32"(31.5) PER TURN
114H 3.25:1 RATIO= 31" PER TURN

Note that these are approximate and assuming the Chinese Senators are similar in size to the originals.

Hope that helps.

Black Pearl's gears:
114h gear ratio 3.25:1 = 33 1/8" per crank at full spool
113H gear ratio 4:1 = 34.5" per crank
Penn gears:
114H gear ratio 2.8:1 = 28.5" per crank
113H gear ratio 3.25:1 =29" per crank

Similar to Mark, I measure the diameter of the spool and multiply it to the gear ratio, the total gets multiplied again with 3.14. This will give you the amount of line per crank.

This is only a formula to give us an idea and to let manufacturers sell their reels.
If you get technical about it, this formula is worthless on fishing reels, the line never stays at full spool when fishing, but it does give us a rough idea when comparing reels.
Forget about all the reasons why something may not work. You only need to find one good reason why it will.

We were typing at the same time conchydong ;D

Bob, keep in mind my numbers are at full spool, line should be 1/4" down from the spool edge. Removing 1/4" from the calculations you will loose approximately 2" of line per crank.

Thanks guys. Going over the numbers trying to decide on a 114hn or not. Hmmmmmm maybe. Always room for one more ;)   ;D

So the fact is that the 114hn has more drag/stopping power over the 113hn with the BP gears. I think that additional weight of the 6/0 is negligible, right?

That's interesting that the 113h has a greater retrieval rate then the 114h, though not by much, despite the smaller spool diameter.  I guess gear ratio plays a relatively larger role then spool diameters?  I always thought a greater spool diameter would allow for marketly greater retrieval rates at lower relative gear ratios.  Maybe that's still the case here.  Any idea why it was decided to produce the 114h Black Pearl Gear set at the relatively low 3.25:1...to maintain strength under high torque/load I assume?

Everything needs a balance, for big game you want low ratio and large spool, in my opinion.
One of my observations of the Senator series is that most reels retrieve the same amount of line per one full revolution of the handle. I believe they knew what they were doing those days.
You might not be able to turn the handle if you increase the ratio considerably more than the 3.25 to 1 on a 114h, unless you use a longer handle, but even then, it would need to be tested. It would be like starting to accelerate a manual-transmission car while in 4th or 5th gear.

Sal, you are exactly right.  Several times I hooked into a Marlin with my Penn International 50VXW when the reel was in high gear.  I could hardly turn the handle in high gear.  I had to shift to low gear until the fish tires.  Then it is into high gear and pumping to gain as much line as possible on the down stroke of the rod.  Dominick 
Leave the gun.  Take the cannolis.

There are two things I don't like about fishing.  Getting up early in the morning and boats.  The rest of it is fun.

A lot of guys here like the heavy duty old Triton series of reels with their large spool capacity, large drag surface area, and very low (like 1:1) gear ratios.  They are often used for fishing heavy 250lb+line, heavy drag, and still able to winch em in with the rod remaining in the rod holder throughout the 'fight'.  Many of the smaller reels (some of the Avets come to mind), have smaller spool diameters and much higher gear ratios (even low gear ratios) are typically greater than in most reels with larger spool diameters.  Makes me wonder about 'effective' or 'productive' achievable torque differences.  I mean smaller reels w/high effective drags, and higher gear ratios, loaded with appropriate spectra, might be comfortable, and fun, to fish with...but The effective torque one can apply (even with a longer handle arm) must be somewhat limited (comparably speaking off course.  Guess it'd be better to make direct comparisons between specific models rather then generalize in this case.

Basically I agree that larger reels w/greater line capacity, greater spool diameters, larger drag surface area, and relatively lower gear ratios (while still maintaining acceptable retrieval rates) are best for truly large game.  Kinda depends on how you fight the fish too I guess.

Keep in mind, that the more line you get back on the reel (regardless of ratio) is going to increase your retrieval rate as the spool diameter increases. Rpm is constant but the surface speed is not due to increasing diameter of line. So having a bigger diameter spool to begin with can help your chance of landing a fish faster than a reel with a smaller diameter spool providing they are similar ratio's. The flip side is the smaller diameter reel will give better mechanical advantage (or torque). If I had to choose between the two I would go for the reel with the bigger spool myself.

The weight of the 9/0 with Black pearl ss Hex Gears, double ss dogs with ss springs, stainless sleeve and Handle with Aluminum frame and a lot more spool capacity is more than negligible for me Bob! ;)
