I pushed my boat pretty hard down on the Rogue Wild & Scenic in September. The water was low and so was my ability to spot new trouble in old places which resulted in a couple of holes in the bottom of my boat. It took a couple of Class II's to "remind" me that a familiar line can change with the water level... so "HEADS UP". DOH!!
My river-side repair with Duct tape stopped the bleeding from both wounds well-enough to finish the float - but I did a lot of bailing along the way. Back home in the garage I assessed the damage: one broken rib, a big "push-up" hole directly below the passenger seat, and a "push-up" hole at my feet.
Here's what I did to fix the "holes". Sanded the area down on both sides. Light coat of epoxy (used a blow dryer to "blow" it in all the cracks). Another coat of epoxy after a light sanding. Glassed the damaged area, more expoxy, more sanding. Final coat of epoxy and sanded smooth as glass.
For the broken rib... I sandwiched it with some scraps of mahogany... clamped, epoxied, screwed and varnished... very sturdy.
The last thing I did was re-apply the UHM plastic to the bottom and THEN... I put three coats of Black Durabak 18 Poly on the "inside" of my boat for extra protection and to cover up my "patch-work". This is GREAT stuff... kinda like an "Arma-coat" for boats. Got it from Randy Dersham and love the way water "beads up" on it!!!
That's it... ready to roll. By the way - the "Bar I put in my boat" got a great work-out this year... it makes the boat much more responsive but it only works if you spot boulders early enough to avoid them!!
Thanks for taking a look.
In case you want to check out the pictures Scott Volstedt took of my boat going through Slim Pickens... here you go.
