Dry Strip Planking

Thank you very much, redreuben, for your detailed post. Do you happen to know if the builders are still around? It would be interesting to hear how they felt the dry build went compared to the wet build and of course to see if they compared the final weights of the three boats...

Okay, so an epoxy putty was used to glue the strips together. I agree, Fall guy, that important to get the hardness similar to the wood for easier fairing.

Does anyone have any rough ratios of epoxy to micro balloons and silica that they'd be happy to recommend I start off experimenting with?

Hmmm, interesting that double bias for the exterior was chosen, effectively doubling the fabric weight of the designer's original spec...

Ooh, and finally, was a male or female mold used?

 

And just to be thorough, this phenomenon is magnified when planking in foam.

 

The cedar hulls were built male, the FRP hulls female, the early FRP hulls were foam sandwich with a vinylester skin, a one off (racing) special was built in 100% VE and post cured.
After my departure I believe hulls went to coremat.
The FRP hulls also had all glass keel grid and frp interior mould.

 

Hi Rob. I am the current owner of the former Riverside Oaks (now Dux Nutts). I am doing a repair on the rear beams and any information you might have on the construction details would be welcome.

 

Lucky you, it's a great little boat. I have no memory of how the beams were made. Sorry.

The correct repair is to replace the beam, or at least the damaged section near the pin. Before doing that, carefully grind back the damaged area and see how deep the damage goes. Maybe the unis along the beam have not been too damaged and the solution is to wrap it with a couple of layers of +/-45.

Is the damage from sailing loads? Where is the boat?

 

Hi Rob,

Thanks for getting back to me. Yes, the damage is from sailing loads - no collisions. The boat is in Adelaide - I sail out of the RSAYS. There is a small group of enthusiastic multi sailors here - half a dozen tris plus one 8.5m box boat cat and a few cruising cats. Our major regatta is the annual King of the Gulf in Port Vincent.

Once I have the boat sorted, the plan is to do some campaigns on the East Coast. Fingers crossed for Airlie 2026.

cheers
