He will know how to adjust the volume for decreased planing area (ie wider boards) or increased rocker. Again the best way to dial in what works for you is working with one shaper on that. Rocker, bottom contours, planing surface area and foam distribution can play a HUGE part in determining the paddle-ability of a board. However, they will give the best idea of volume you can at home, and they are free.īut, keep in mind paddling is NOT proportional to volume. If they make a super big tub like that, I want one, cause it will make bath time action with the lady a lot more manageable.Įven AkuShaper or BoardCAD will not guaranty a proper measure of float unless you know the density of the foam used and take A LOT of measurements. One shaper can shape two 6'2" x 18 3/4" x 2 1/4" shortboards and the volume and float can be wildly different.īrian (Greenlight) is a good friend of mine, but sorry man, I don't know any bath tubs that will fit a surfboard. There is no other technique that will assure you that your numbers are proportional. They can add or subtract volume to change the float and use the same foam as they did on the last board. The same technique applies to shapers who use a CNC machine. Next time you order you can then tell them to go up or down in volume and you know 100% that is what you are getting because they know what density foam they used on the last board. But in reality the value they are calculating for you is FLOAT or BUOYANCY not volume because the same volume can be occupied by two different density foams and the float or buoyancy will be completely different. They can calculate the volume based on the known density of the foam used and the weight. You can order a Coil and Mike and or Kirk will shape it for you. The Coil guys were really the ones who perfected this process and quite honestly their boards are by far one of the best options available so that is two reasons to order from them. Mook, easiest way to dial in your volume is to stick with the same shaper who calculates volume from the start. 75 cubic feet/100 lbs, eggs and mid-lengths 1.00/100 lbs, hp long 1.25/100 lbs, and classic long 1.5+/100 lbs.Įdit to add that 1 cubic foot = 28.32 liters, I like using cubic feet more because it's easier to see percentage changes. 50 cubic feet per 100 lbs of rider weight, fishes and hybrids about. On one of those 2007 threads I laid out my general guidelines for different types of boards. You young rippers use less, old bastds like me, like more
75 Cu Ft per 100 lbs for hybrids/Fish (adjust for age/fitness/personal pref) 5 Cu Ft per 100 lbs for shortboards (adjust for age/fitness/personal pref) There is also some interesting estimates by guys like Mike Daniels at Coil and an Aussie named Dave - (Diverse surfboards) which talk to appropriate vol for weights and styles of boards.
