This is the bushing for the Forte Carbon Tube 150 (FTC 150). Forte applies 4-axis continuous fiber braiding over an aluminum mandrel to produce extremely durable and tough carbon fiber tubes. The interlocking fiber braid is wet-out with epoxy resin. The end result is a seamless braided tube with very precise compression or bending characteristics.
Forte builds its parts to specific lengths and weights, and may be straight gauge or tapered. The FCT (Forte Carbon Tube) 150 requires a BU150-150 bushing and has an inside diameter of 1 1/2 in. (28mm), an outer diameter of 1 3/4 in (44mm), and a maximum length of 10.0'.
E-Scow, Etchells, and Soling sailors create spinnaker poles and prods out of these tubes by using Forespar UXP-150 FP304054 end fittings.
