I just emailed the author yesterday about the procedure for creating the offsets/forms for the Guillemot "L" version described on the website for us larger folk (6'-1", 230 lbs, size 12 shoe). I would like to know if anyone has done this and/or built the Guillemot "L".

As for the extra reference line, it could be the 4" line at the top of the strongback hole but, I haven't cut wood yet so what do I know. Been lurking since a visit to Pt. Townsend, WA this summer. I got bit by a wood strip kayak bug while there.

: I am making the forms for a Guillemot from the offset tables in "The
: Strip-Built Sea Kayak" book. (Great book) My question is about
: reference lines. The suggested lines are CL, DWL, Diagonal line, and
: sheerline. All my lines are perfect except the sheerline. In photos in the
: book there is another line that seems to be a reference line above the
: DWL. (pg 71 fig 5-19, pg 72 fig 5-20, pg 75 fig5-27.) Isn't the DWL the
: common line on all the offsets? Should I just create a second line, maybe
: three inches above the DWL as a second reference line used to keep the
: forms straight.

: Also I am a larger person. 6foot one inch 250 lb. I am thinking of enlarging
: the forms to "fit me a little better" maybe 21 inch beam to 23
: inch beam. Has anyone tried this? Thank you for any information you can
: give.
