has the foam held up so far adhering to the HDPE? or have you not had it on the water yet? also, are you going to build a surfgate of some sort for this rig? i know you probably don't want to drill into the hull on that thing like you did the supra, but a malibu-style gate is easy to make and attach without drilling.
