Transom Dagger Boards

 I made my transom dagger boards last week. Seeing they are not a compulsory part of the build & they are open to builders interpretation, I decided to make them out of materials I had at hand. That being two layers of 15mm Divinycell foam with 2 laminations of 450 gsm double bias fibreglass cloth & epoxy resin. This has made for very light & very stiff dagger boards. I'm yet to make the cases but will make them as light weight as I can as well.     

                        

Shaping a foil to the foam blanks. I made a jig to support the foam when shaping the second side of the boards 

--------------------------------------------

     

Resin coated the finish shaped boards then wet out 2 layers of 450 gsm double bias on a sheet of plastic

  

                

Lay the board onto the wetted out fibreglass & wrap around the board 

------------------------------------------------

            

Previously prepared peel ply, bleed cloth, & perforated plastic for wrapping laminated board. Remove wetting out plastic & lay board onto peel ply, etc 

                       

Wrap the board in the peel ply, etc then put some shade cloth over the top. The shade cloth helps the vacuum to be pulled through the entire job 

---------------------------------------------- 

     

Put everything into the vacuum bag, fit the hose & seal up the bag

Open the valve on the vacuum pump. Vacuum bagging makes it very easy when it comes to fibreglassing odd shapes like the rudder & dagger boards 

------------------------------------------------------------

After curing the dagger boards & rudder were sanded & 5 coats on International Interprotect High Build Epoxy Primer applied. Ready for sanding & hopefully not a lot of filling.
