Webs can be made from solid fibreglass which has been laid up flat on a laminating table.   An alternate method is to fit plywood or hardboard webs and then install the laminate on either side including the bonding on to the hull.   The webs are generally set on ribs or stringers so as not to create a “hard spot” where they meet the hull.   The tops of the webs should be fitted with a 1” x 2” [25mm x 50mm] timber or foam rib.   Cover this rib with the web laminate, excluding the very top, and it will add strength to the arrangement and provide a landing for the plywood sole.   Before proceeding, study the section of your plans covering the installation of the ribs, stringers, web floors and bulkheads.   Often the bulkhead positions will govern all the spacing of the transverse webs, so marking out the bulkhead locations is an important step in your building programme.   We generally recommend spacing the webs and ribs, if required, equally between the bulkheads, but there may be exceptions to this rule so the best idea is to follow the designer’s recommendations.
