Thanks for this very informative thread.
We have purchased a Birchwood 25 Interceptor this past summer and are having some issues. Would be great if anyone could tell me more about the hull structure, especially if there is a foam core in between the outer hull and inner hull or if its hollow / solid.
Backgroud: We just found out, that the pre-owner just recolored a fracture in the grp (starboad/bowside). If it´s solid or hollow it won´t be a big deal to repair. In case it´s filled with foam, it might be we have some work for the junk press. :-(
Best regards
Phil
