Upgrading lifeboats

I am replacing the kit lifeboats as they are too large and not very well detailed.  Other people have used the lifeboats from the Airfix 1/600 Queen Elizabeth but I didn't want to waste the kit so I am just making resin copies of those lifeboats.

The original QE sprue is on the left and the beige resin copies are on the right.

Here is my two part mold for the lifeboats.

This is the resin casting kit I used. Actually I think this is only the mold making kit. It contains material to make the silicon molds.
