Lines, inboard plan & profile, construction and bottom planking plan, details, scantlings.
I began by scaling Messenger's plans 50% and taking those measurements for the offsets. The
offset table for Louise Marion reflects those dimensions to an eighth of an inch.
I drew up the lines from measurements taken from the offset table.
The keel, skeg, centerboard case, transom, stem and sternpost.
Perpendiculars were taken from the offset table as well.
I generated several sail plans. I finally settled on a sprit rig for simplicity and ease of handling.
The next step was lofting. This is the process whereby plans are drawn up full scale. Patterns can be made from the loft plans. I found this to be especially helpful for measuring angles, bevels, and curves.
