The biggest difference I noticed between the Touring and the Glide was stability in rough water, and how the nose of the Glide reacts when it goes under the water in downwind conditions. I had the 12'6" Touring but the nose is identical to the 14'. The nose on the Glide and SB Touring are very different. The Touring has a very defined, high, and sharp ridge on top, whereas the Glide only has a slight ridge that doesn't extend as far back. The Touring has some of that yawing effect, or side to side movement when the nose goes under the water, and the Glide just charges straight ahead and comes back up smoothly. The defined peak of the Touring is for shedding water and piercing waves upwind, but it makes the board a bit harder to control in downwind conditions. The Glide is easier to paddle in cross chop and quartering swell in bigger conditions, and the Touring definitely gets pushed more by cross chop and quartering swell, and I believe this is largely due to the nose of the Touring that catches the swell. There is more rocker on the Glide, which helps in downwind conditions, and probably in side chop as well.
One area where the Touring is better, is upwind performance as the design pierces incoming waves and chop a little better than the Glide, which has more rocker and more board slap in smaller conditions. When it gets bigger, the gap closes between the two upwind, but I preferred the upwind performance of the Touring over the Glide. The Touring gets the nod in flat water performance too with less rocker and the pintail out the back. I had my Touring in the ocean in trying conditions, and it did fine considering the primary design intentions were for inland paddling, and not ocean performance, but there is a noticeable difference between the two in downwind conditions and paddling into cross chop and quartering swell. The Glide has more stability in rough water hands down. The Touring will be fine in calmer to moderate conditions on the ocean and it does just fine in knee high chop and backwash you typically experience when paddling close to cliffs, etc, and with practice you would be able to go in bigger conditions for sure. The Touring just isn't as stable and doesn't perform as well as the Glide when the going gets rough. The wood Touring is a beautiful board, and with the tie downs fore and aft, makes for a versatile distance board. I added NSI tie downs to my Glide and they work really well and the Glide also makes for a great overall touring board as well.
I'm going to try and add some pictures for the Glide and Touring side by side to show the difference in rocker and the high ridge on the nose of the Touring. There is no difference in nose design or rocker from the 12'6" Touring to the 14' that I can tell.
