Ventura Deck Supports


I just purchased a Ventura II, 1984 with the nice silver fade-to-blue paint job. Has a 140hp Johnson.  $3000!!!!  We never see Hydrostreams here in Wash state.   

The center deck support up under the dash has lamination only on one side of the vertical plywood support.  Should I laminate this plywood support fully and get it to solidly support the deck?  Would I have to grind the old 'glass to get a good bond with the new lamination?  Additionally the horizontal dash supports under the dash sides, left and right, are also cracked.  Should I wrap them with mat and relaminate them as well? 

Lastly, the last owner drove a wood screw right through the hull near the bow while installing the battery box (the screw is still dangling there) and just plugged around it with silicone, I will pull the screw, should I try a fancier fix than just silicone? 

More to come.  Thanks for your time Randy.



Congratulations on finding a Ventura. Sounds like somebody (previous owner) put the center support under the deck after it was built. I do not remember Ventura's with a vertical support under the deck. No worries though, since it is already there, you might as well repair this support and your dash supports also. Grind the old glass to remove dirt and grime and then apply some mat virtually anywhere you can get a good bond. The nice thing about fiberglass is that you really can't screw it up. At the same time, you could fix the screw hole using a product called Formula 27 from Evercoat. You do not want to use products such as Bondo or Duraglass because they absorb water. Reinforcing your deck brace and sealing it is a good idea for longevity and in case some big dude sits on the front of your boat. So I am all for the project. Have fun with your new rig.
