And so the Back Cove 30 begins

Over the next few months I am going to follow each step in the development of a new boat design. I hope you'll enjoy learning more about how designs are taken from computer screen to water.

"Tools" for the purpose of this blog are molds and molds for the uninitiated are the tools from which fiberglass parts are made. Before a mold can be built a full size plug of the part, one that looks just like the actual boat, has to be constructed. BTW that is not always true there are methods of going directly to female molds but that is generally only used for one-off designs.

Today, plugs are carved from large billets of foam using the naval architect's drawings to guide the multi-axis router over the surface and create the form. Step one is to make the plywood forms that you see here. 

 
  
Those forms are erected and covered with wire screening. Then, foam is sprayed on the exterior to give a very (very) rough "buck" of foam that the router will carve.

Next time we'll show you the router in action.

I've been waiting for the Sabre 40 sedan information on the Sabre website to be compeleted for what seems like ages, currently only 3 photos and not much else, come on guys!! this boats been around for a while now surely you can load a little more info, coming from Australia I can't just go and look at one easily without a trip to the states. Unless you guys "give" Jed at Emarine a demo model of course!!!

I'm a Back Cove 33 owner (hull No 076) and use my new boat to travel to and from the Australian mainland to our vacation home on Kangaroo Island off South Australia, recenly visited Sydney and drove the new BC37 through the harbour, great boat, not sure about the mid level galley though, can you look at the windscreen washers design, currently you need to rely on having the fresh water pump turned on and individual wipers can become blocked easily and did so in the 37, yes you guessed it the drivers window. The water at best just dribbles out and only wets a portion of the window, could I suggest a high level (above the window) nozzle that sprays over the entire window surface and a dedicated pump activated by the washer button.
