I Ifeel like i've created a monster here.

Hello Everyone, Originally my intent was to enlarge the prospector, without going to a photo copy place. Yes.

news flash!! It worked like a charm!!!

I photocopied the ruler increasing it by 10%. The photocopy was then laminated in plastic and then the straight edge was cut using a paper cutter. This made a pretty usable ruler. If i put the photocopied ruler next to the real ruler the 5" lines up with th 5-1/2" mark. Exactly 10% I lofte...

check out the link.

i used different color markers so it would come out well in the picture. little black dots is the original lofting unchanged by any percentage. Big orange dots are points that look good. The red ones are all screwy... I made notes with arrows to them. http://farm3.static.flickr.com/2590/4158304701_8...

Hello Everyone, I have decided on building an enlarged version of the "Ranger". The reasons in case your wondering... 1. When increased proportionately in all directions to the same length as a "Prospector" It has way more capacity, a higher free board and much higher stems. (I a...

Hi everyone, I am struggling trying to decide between 2 of the designs in the Canoe Craft book. For me this is a serious investment of time and money and I really want the boat I choose to fit my needs in the end. The two boats in question are the “Ranger” and the “Prospector”.
