Got to keep busy so why not build something with my grandson.
The Story
In the builder’s words
Semi-retired and as a hobby I like to work with wood, fiberglass, electronics and engines so the CANDU-EZ is perfect. I figure this project will take about 18 months and will bring years of fun with my grandson and granddaughter (who the boat is named after). The build is a WIP right now.
Builder Knowledge
Practical lessons from this build
- What I Would Do Differently
I would cut and position the hulls a bit differently in order to flare the top of the bow about 1-2 inches wider than the bottom shape.
- Most Difficult Part of the Build
I disliked cutting the longer thinner parts like the chine logs, rub rails and gunwales.
- Best Modification
I added a 12in deep box keel to mount the diesel engine low enough to have the shaft almost flat.
- Would I Build This Design Again?
I think one time will be enough

The Build Begins

JUNE 2026
The start of the build
Prior to the start i had been collecting miscellaneous parts and reviewing the plans on Berkley Engineering which i ultimately purchased (CANDU E-Z). I also purchased laminating epoxy, 6oz cloth, biaxial tape, cloth tape and ACX plywood for most of the build. All fasteners that I used were stainless steel.
Before the build I also purchased a used Yanmar 1GM diesel engine, transmission, shaft, stuffing box and prop. I needed this to properly dimension out the box keel and engine placement
-
JUNE 2026
The bottom & box keel
Bottom and Box keel sized to accept engine and shaft length I had. From the start I decided to stretch the plans of the boat length by 18 inches (I will also add 2 or 3 inches to the cabin height). The depth is 12 inches and the sides of the keel are canted inward 15 deg to make it more streamlined. The keel’s displacement is a bit greater than the almost 200 lbs the engine, transmission, shaft and prop are. There are 3 bulkheads to separate the compartments in the keel. At this point in the build i simply had a leveled 10’ x 6’ 2x4 frame on the floor of my garage to ensure flat build.

JULY 2026
Completed glassing of bottom and added stainless guard on bottom of keel.
Completed glassing of bottom and added stainless guard on bottom of keel. There are 4 layers of 6oz cloth minimum on the bottom with 6 to 8 layers on all inside and outside corners (including 1 layer of biaxial/mat).

AUGUST 2026
The hull takes shape
The bow stem was installed, hull sections measured, cut and butt joined. Then the hull sections were fitted. This was a major milestone for me because now visitors checking on what I was doing believed it was really a boat!
(Don’t mind the messy shop. Every week or so I do a cleanup…..most of the time).

Miscellaneous side projects
Along the way my attention gets drawn to some other related side projects. Here are a few;
Old truck air horn restoration
Shift / throttle controls
Name platesAfter restoring these air horns I come to find they work on vacuum , which a diesel engine does not have. I purchased an electric brake booster vacuum pump to run them.

Mike D
Founder MemberBuild ChroniclerRecently, semi retired IT professional. Downsized to a home 15 minutes from Sandy Hook Bay in NJ. When looking for this house first priority was to be close to the water and second was to ensure a 2 car garage…but no room for cars in this garage (you will see why in the build photos). I am water lover and sailing…
