"The Keeper has become my favorite board to ride in small & medium waves, and I want to keep being able to surf it in plus-sized surf. Why should I have to switch to a shortboard or step-up?"
Well now, you don't have to!
There are many of us Keeper owners, myself included, who have a tendency to push the board to its limit & beyond, surfing the Keeper in head high plus surf. And it's an absolute weapon for medium to bordering-on-bigger days that seem shortboardable at first glance, but in reality are just too fast & racey to make most waves easily on a shortboard. Sometimes we make it work by easing off the gas a bit, other times the Keeper simply gets outgunned via too much speed/lift/width and not enough rail length to provide the control & stability needed for such waves. So from my own desires, and requests from my customers & team riders I've developed a new shape based off of the Keeper to optimize it for where the Keeper's ceiling leaves off: in plus-sized surf. Welcome to the family: the Keeper Plus.
The idea here was to keep as much of the coveted ride-feel & personality, speed & flow of the Keeper as possible while adapting the shape to its bigger ideal & functional wave range. In short: it's a longer, narrower Keeper wth a bit more rocker and more aggressive bottom contouring plus a quad fin setup selected as the best option for most surfers (though other fin setups may be chosen: upright twin, twinzer, twin keel, etc). The fin setup was probably the aspect I struggled most with as the twin keel is such a huge part of the Keeper's personality, but we cross a threshold into the upper and more critical end of the wave range with this board, and I feel a quad is simply the optimal choice for most surfers. My choice fin set is the FCS II Split Keel quad set, which puts the ride-feel in between a twin keel and a performance quad set - a perfect option for the purpose of the Keeper Plus.
A similar approach to the outline/plan shape, foil & rails are in place, again modified for bigger waves. Aside from the switch from twin keel to quad, the bottom contours are the starkest change to the shape design. Utilizing the bottom contours from the Keeper in the tail half of the board as an analog, they're deeper with the addition of single concave under the nose & front foot. The purpose of this is to harness more wave energy & power than the Keeper typically sees, reducing the looseness & ability to break free quicker and improving grip & control.
The Keeper Plus is designed to be surfed approximately 2 to 4 inches longer than your standard Keeper, depending on personal preference. My personal Keeper Plus currently is 3" longer (I'm 170 lbs and surf a 5'4 Skiff, 5'6 Keeper and 5'9 Keeper Plus).
Here's a graph depicting the wave coverages of the 3 true fishes: the Skiff, Keeper and Keeper Plus. The inner, darker bubble for each model represents their ideal wave range where they will surf the easiest, feel the most natural and perform optimally. The outer, lighter bubble represents their functional wave range where they will surf well & reliably for most surfers.
