[[File:MK-I-Runners.jpg|thumb|MK-I with supported mast tip, double spreaders, and possible running backstays]]
The Impulse 26 was produced with several different rig configurations according to multiple owners that have compared different builds in person. The most common configuration produced was a ⅞ fractional rig with a single set of spreaders and a permanent backstay connected to the unsupported mast tip. A handful of the earlier builds were produced with the ⅞ fractional rig, double spreaders, a supported mast tip, and running backstays. This configuration was reportedly overly complicated and weak, to the point that mast breakage was common.<ref>[http://forums.sailinganarchy.com/index.php?/profile/16743-jangles13/ Jangles13], [http://forums.sailinganarchy.com/index.php?/topic/39355-impulse-26/&do=findComment&comment=3065253 Sailing Anarchy Forums], November 16, 2010</ref>
=== Mainsail ===
The Over-sized ⅞ fractional rig on an Impulse 26 equates to a rather large mainsail and boom. The Impulse 26 mainsail is generally loose footed with two full length battens at the top and 3 partial battens on the bottom ⅔ of the sail. Thus the boat was designed with many controls to handle the large amount of power it can produce in a fresh breeze.
<br />
Those controls are as follows
*6:1 mainsheet
*Recessed main sheet traveler
*16:1 boomvang
*4:1 outhaul
*32:1 magicbox permanent backstay
=== Headsails ===
Generally the Impulse26 is commonly sailed in light air conditions with a 145-150 genoa. Although some owners have opted for a 125-135 number two, with a flatly cut main, it can still be sailed in an overpowered configuration fairly easily. Once the conditions permit, a 100 jib will keep the boat pointing and manageable.
=== Spinnaker ===
The spinnaker on a ⅞ fractional rig can leave the boat underwhelming downwind in mild conditions. The helmsmen must be diligent of keeping the main sail trimmed correctly as it is still a substantial source of power. Having a smaller spinnaker and a large main is beneficial in fresh conditions as the spinnaker can be buried easily and the boat rapidly de-powers.
