Was I ever wrong

My calculations were way out to lunch. Steve and Larisa have completed a second half hull and here are the times in Steve's own words.

Let's see. Two people 
   Two easy days to cut and prepare
      Cut and prepare foam
      Rough cut glass
       Prepare tubing
       Gel coat the night before infusion
       14 hrs
   One day to infuse
       7 hrs
   Remove bag, peel ply, etc
       2 hrs
   One day to groove and put on frames -3 hrs
   One day to bend and glass -5 hrs
   Remove from forms and take outside about 3 hrs
    Extra help 5 hrs ;-)))
    Computer planning 2 hrs - used the Turbo-cad program to calculate the fiberglass cuts and resin line lengths.

14+7+2+3+3+5+5+2= 41 = 40-50 hrs

When working we do not waste much time. 

The bending is real fast and easy. 

Larisa and I raised the panel onto the forms by ourselves. A couple 2x4s and concrete blocks helped.

Larisa and I removed all but the last 4 forms but had help for 30 minutes to lower to table and haul to back yard. 6 people can easily carry a half hull. With a good two wheeled wheel barrel I think two people could move it, definitely 4.

2nd panel easier than first.




So.....we are looking at 40 - 50 hours for two dedicated people to build half a hull or 100 hours for two people or 200 hours for one person to build two half hulls. Of course even two people need a bit of extra help once in a while and the two have to be joined together. But really........the small amount of time spent to this stage is ridiculous to anyone who has built a hull the conventional way.

I guess the best thing to do now is start at the beginning and go through all the steps to get to this point.
