I was doing some EFT'ing before I purchased some new Exhumers and had a couple questions about the best Ice mining ship.

Assume I have a dedicated hauler and cargo size is not an issue. I was looking at effective ice units per hour.

Yes, i know the hulk gives you 3 units of ice per cycle but its cycle is proportionally the same as a mackinaw and skiff.

Here's what I came up with (including Orca bonuses).
Hulk - 3 units per cycle
207.54 secs per cycle
69.18 secs per unit

Mackinaw - 2 units per cycle
128.9 secs per cycle
64.45 secs per unit

Skiff - 1 unit per cycle
70.83 seconds per cycle and per unit.

How is it that the Mackinaw is coming out faster than the Hulk? Am I doing something wrong in EFT? I thought the Hulk was supposed to be the end all and be all of fleet miners?

its really simple. Using eft , All level 5 both ships ice harversters upgrades low and ice harvesters II plus rig . You will have equal amount od ice on both ships when you gather 6 blocks of ice

Mackinaw gather 2 blocks at 157.5 secs x 3 = 6 blocks at 472.5 sec
Hulk gather 3 blocks at 218.6 x 2 = 6 blocks at 437.2 sec

So hulk is faster. Any other improvement to time you will make from implants or booster will still affect the same ships equal so hulk will be faster as well. The only way for mackinaw to be faster is if you dock the ships to unload the ice.

My Hulk cycles in 121.7 seconds. 5% Yeti Implant involved.

The Mackinaw has a small margin over the Retriever:
* Ore: 1% more yield per level of Exhumers
* Ice: 1% reduction in Ice Harvester duration per level of Exhumers

Exhumers 1: 1 / (1 - 1 * 0.01) yields 1.01% more ice, which takes about 100 cycles to realize
Exhumers 2: 1 / (1 - 2 * 0.01) yields 2.04% more ice, which takes about 50 cycles to realize
Exhumers 3: 1 / (1 - 3 * 0.01) yields 3.09% more ice, which takes about 33 cycles to realize
Exhumers 4: 1 / (1 - 4 * 0.01) yields 4.16% more ice, which takes about 25 cycles to realize
Exhumers 5: 1 / (1 - 5 * 0.01) yields 5.26% more ice, which takes about 20 cycles to realize

Note that you can't harvest less than a full piece of ice, and ice cycles are very long, so the only way to get the bonus yield is to harvest ice for quite a long session of time.

i.e. At Exhumers 3, after 33 Retriever cycles the Mackinaw has saved enough time for an extra cycle = 2 more ice.

please tell me where these Ice harvesting rigs are ???

It is listed under Medium Electronics rigs.
