Which one are you planning on building first?

Question.
Is the extra draft added to her bum or deck level?
I've printed 13 copies of the sections one for each bulkhead ready to increase the bulkhead shape height or depth wise.

Thanks Damien.

The Etona that I saw modified had the bottom of the hull cut off and a new deeper section grafted on. It had already been built and finished when the stability issues were found out.
I'd suggest on a new build that you alter the hull sections before starting building.
What I've done in the past is to scan the hull sections into the computer as a JPEG. Then import them into Word
and use the "size" function to stretch the hull lines by the dimension and direction required. I hope that makes sense. 

Thanks Barry, I imagined making the the hull then gluing 25mm sq balsa in place  and then carving to shape.

Decided on PS Enterprise first as she's flat bottomed and easier to add 25mm to draft.
The top section shows the original lines the lower section added to give the original hull bottom shape is this satisfactory?

Upon noticing the altered frames drawing Jo (missus) says whats this after explaining it she asks why bother you've 3 other paddlers that haven't seen water yet what's the chance this one will. my only answer was UUUUUUUUUUUUUUUUUUUUUUUUMMMMMMMMMMMM.

Very astute Mrs!!!!

A man after my own heart...I rarely finish any project, boat or plane etc. The latter never fly and the boats get one outing if that.

The pleasure is in the making.

Simple fact is i'm not up to launching them these days age and polio affected right foot now at 80deg to right of fwd and getting worse by the year. I've denied it for ages, so i'll just build and admire.

Sorry to hear that Damien.

I cant get down to ground level these days so would need to build a launcher like yours.

Isn't old age wonderful!

Can't complain much I've lived 24yrs longer than expected, after pituitary tumor removal in '94 the hospital doing the radiation treatment told me to go home in November '94 as I'd be more be more comfortable but wouldn't live to christmas.
