==== MK-II ====
[[File:MK-II-cockpit.png|thumb|MK-II Cockpit Example]]The MK-II deck layout features a sliding companionway hatch. The deck itself is balsa cored. The winches in the cockpit are centered between the main traveler and cabin making for more centered leverage for trimming. The edges are also rounded off making crew work more ergonomic. The tortured transom has a wider step. The MK-II also features a beefier structural build with noticably noticeably larger stringers and hull thickness.

[[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.
