A much bigger boat for us... for the last 14 years, since I built and launched her, we've been cruising on our 12' Welsford Scamp LUNA. This is going to be fun!

Rounding mast

While waiting for the paint on the lofting plywood to dry, we spent about a hour rounding the mast. The area in the photo is where it will transition from the 8 sided base to round. Just starting that job, there will be more to do on it, later. But now, lunch, then to get on with the lofting (if the paint is dry).

Lofting

Laid plywood on shop floor, painted it flat white, laid out a baseline, waterlines, stations, and started to draw the lines at full size.

Lofting, continued

Lofted the halfbreadths, and checked the bodyplan against them. We forgot that the halfbreadths gave valuable information to the bodyplan, so had to make some adjustments to virtually every station. Obviously need more practice lofting!

Lifting patterns

More lofting, and then lifting patterns from the lines. We placed nails, sideways, with their heads on on the line we wanted to lift. Then we put doorskin ply over top of those nails, and stomped on them. Lifted the doorskin, put finishing nails into the impressions the nailheads created, put battens around them, drew the lines, and cut the doorskins out on the bandsaw.

Nobody else here is logging a Spartan II yet. See the boat.
