Taking of lines; MARIANNE of Bayfield





                        

Boat lines; Boat Building Notes by Garry Couch

MARIANNE of Bayfield, part 1

 

                       

October 12, 2012 was a beautiful autum day in the orchard country overlooking the Aposltle Islands of Lake Superior.  Taking advantage, I rolled into Jim Erickson’s back 40 on the hill and got to work documenting lines off one more old boat from a day gone by.  And very happy to be doing so, especially drinking Jim's fresh cider.


Jim's grandfather Martin Erickson had Evan Christensen build MARIANNE when he (Jim) was just a young lad in 1940.

Jim recalls the keel coming from up Whitting Road and the boat was built near Bayfield's southern waterfront.

 Work notes;

 - She's leaning a little and compensations were taken. 
 - Measurements were taken to the out side of the steel sheathing.  The covering was well done, with the hull rather fair and true.  Exact thickness unknown.
 - This is the second Even Christensen boat I've documented, the other being the Bobbie.
 - Don swung by and caught some of the ups and downs of the trade.  Thanks for the photos.

Real action;

 

measuring a half-breadth point from the base up.

 

Generally speaking a base line (usually parallel to the keel),  and a center line (or line  parallel to the CL) are established - and perpendicular measurements are taken from them - along a station line which is represented by the big square.
