Various parts of this site use design terminology that might confuse the average surfer or be interpreted differently by other shapers, so we thought we'd briefly describe our meaning for these terms.

Hopefully, this will help the reader better understand what is being presented.

Some of this falls into a brief discussion of our design philosophies to help readers understand where we are coming from with our designs!

Tucked Edge


A tucked edge is an edge shaped into the bottom of the board where the rail curvature intersects with the bottom plane. This edge can vary in hardness along the length of the rail or might not be present in some parts of the rail.

Typically, all our boards feature a full-length tucked edge from nose to tail. This edge is very hard and close to vertical in the nose and tail. Through most of the rail, the amount of tuck will increase from the nose to the board's wide point and then decrease again towards the tail. The amount of tuck is the distance that the apex of the edge is located from the apex of the rail.

The tucked edge aims to provide release at the transition from the bottom to the rail. If this edge did not exist, the water would tend to wrap up off the bottom and around the rail, creating additional drag. Adding an edge, the water can release cleanly off the bottom, improving performance!

Chined Rail

CHINED RAIL - Bottom Outline

In addition to a tucked edge on the rail, we often employ a chine around the perimeter of the outline on the bottom. The chines help the board release and make the transitions into turns faster and more fluid.

The chines are flat and beveled up from the bottom of the board. They feature a hard edge on the inboard edge to facilitate water release.

Chines are an integral part of our VCTR bottom design.

Bowled Double Concave


Double concaves in the tail of modern surfboards are a common performance feature. They enhance speed and looseness in a board. Our high-performance boards have this feature, but ours is shaped differently than the regular version. Ours features a rounded bowl at the center, slightly higher than the rails. This bowling effect pushes the bottom of the concaves out closer to the rails, focusing them more toward the fins.

The fins sit within the concaves on the face closest to the rail. The depth of the concaves varies based on the type of board and is most prominent in our quad designs, where the goal is to push the water flow toward the fins to enhance their performance!

The motive for the bowl is that it enhances the board's ability to transition from one rail to another by rolling on the bowl! Additionally, the bowl limits the tracking that could occur if the concaves had a sharper apex by eliminating the ridge running down the center of the board.

Parabolic Nose


Sharp noses on a surfboard can cause serious injuries to a surfer should the nose strike them. To provide a safety nose on our boards, we developed a parabolic nose, where the tip of the nose is shaped into a parabola at the tip.

It results in a nose that is entirely rounded and hence blunt, thus making it much safer. We incorporate this into the rail shape in the nose by adding a very slight beak to the nose that increases the thickness to add more safety!


This is our name for the veneering technique on some of our boards. It is very similar to the Timberflex® construction technique but differs significantly.

This construction technique has a layer of veneer vacuum bagged to the top and bottom of the board. Because our designs employ a tucked edge on the rail, we have developed our unique approach to applying the veneers to our boards. This technique allows us to preserve and enhance the tucked edge by having the veneer run right to the edge.

Our technique is more time-consuming than T-flex, but it guarantees us we will get the quality edges we care about. In most cases, the decks have a layer of either 2 oz or 4 oz underneath the veneer with a single 4 oz over. The bottoms have the veneer applied directly to the foam and then covered with a single layer of 4 oz. Everything is laminated with Resin Research® Epoxy Systems resins.

Recently we have switched to primarily using this technique to apply deck patches to our boards. Using the method for deck patches, we can better control the board's flex characteristics when using a polyurethane blank.

We have also started using PVC foam instead of a veneer in this application. The foam allows us to make a deck patch that is very dent resistant, and the foam absorbs less resin than the veneer, making it a little lighter.

Typically, the foam is only 1/8" thick, but we have also been experimenting with thicker foams allowing us to add floatation to thinner, more performance-oriented boards.
