I have a 73 Tri-Hull. I know this boat has three stringers running front to back (typical?). Are there any braces running side to side? is that common? I am asking because I am trying to setup proper drainage to the bilge. Of course VIPs repsonse was..<br /><br />"Keith,<br /><br />There is no longer information available on this year model boat.<br /><br />Sorry!<br /><br />Best Regards,"
