Deer Isle Tammie Norrie Build

[Bill Wiegmann]

My latest build is a Tammie Norrie designed by Iain Oughtred:



I was looking for something that I could use as a reasonably burdensome tender for my big boat, but also a boat that I could use to teach the little kids in the family how to row and sail. I contacted Iain Oughtred by e-mail and he concurred that the 13' 6" Tammie Norrie would fit the bill. I bought the plans from Iain directly; payment by PayPal was a snap and in two weeks I had Iain's beautifully drawn plans.

I've always liked that design. Best of luck.

To expedite the build, I decided to buy the planking kit from Hewes and Company. The kit includes 6mm okoume planking, a transom, building molds and full-size patterns for the stem and transom. I had Hewes do the transom and sheerstrake in sapele, which I plan to finish bright. Hewes's instructions made it clear that the stem and transom are slightly differently shaped from those in Iain's plans, to facilitate the pre-cut planking shapes.

Here are the molds being set up on my building jig:



Here is the transom laid over the Oughtred plans:

The planks come in two pieces with a pre-cut scarf to join them. The alignment process is pretty simple: a series of holes is pre-drilled in the edge of each piece, along with one hole in the middle of the scarf joint; you tack one end of the plank down to your work surface with small nails through the holes and then add the second end joining the two with a nail through the scarf joint hole; you then pivot the second half around the scarf nail until a string strung around marked points on each half just touches the scarf nail; sight along the plank lines to make sure they are in alignment; and then tack down the second half of the plank. You then snip off the heads of the nails so that you can slip the second pair of halves for that plank over the top to double check its alignment; take everything apart for glue up; and put it back together for final assembly. Here is a plank being glued up on my workbench:


The transom came as 6mm ply. I was thinking of building a frame for it to give it more substance, but, having decided that I wanted to build the lug yawl rig, I realized that there would be a lot of transom penetrations for tiller and mizzen strut and attachments for the mizzen mast. Rather than build a frame that tried to beef up each of these areas separately, I just decided to glue up a complete back up for the transom out of Honduras mahogany:


The sapele ply transom was then glued to this blank and I used a router to cut it to shape.

Re: Deer Isle Tammie Norrie Build

I used the pattern provided with the kit to make the inner stem. First, I glued up Honduras mahogany planks to fit the curve of the inner stem:


I then cut out the stem according to the pattern and roughly shaped it on the workbench:


Here is the inner stem attached to the building jig:


After fitting and beveling the keelson, came fitting the garboards. These were a little tricky. After beveling the forefoot as best I could, the garboard plank edges did not match the lines taken off the Hewes inner stem pattern. To double-check the setup, I remeasured everything and then tried out the forward halves of each of the other planks in turn to see where they would land. It looked as though everything would eventually mostly catch up to the drawn lines, so I went for it. Here is the garboard being fitted:

The kit enables planking to proceed pretty expeditiously. Here is the hanging of the fifth plank:


The kit comes with those convenient OSB plank clamps.

Here is another photo of where things stand now:

Looking really good! Love that design too.

Re: Deer Isle Tammie Norrie Build

Pretty boat! I look forward to seeing her on the water someday!

Re: Deer Isle Tammie Norrie Build

Today I hung the whisky plank on my Tammie Norrie. Final plank on port side:



Here is the starboard showing all the planks:



The sheerstrakes are sapele, hence the darker look. Next steps: stem and keel.

Re: Deer Isle Tammie Norrie Build

I built my stem out of laminations of white oak, glued together with West G-Flex epoxy.

Re: Deer Isle Tammie Norrie Build

Watching with interest Bill, another set of plans I have tucked away! Looks to be a great job youre doing. Nice even planking at bow

Have you decided on a rig?

[Bill Wiegmann]

Re: Deer Isle Tammie Norrie Build

Thanks, Andrew. I am planning on the lug yawl rig.

Re: Deer Isle Tammie Norrie Build

Looks very nice, Bill. You'll be turning the hull soon? I'm building a TN from plans (no kit), but my progress is best described as glacial.

Re: Deer Isle Tammie Norrie Build

Thanks, Al. I am currently attaching the rubbing strakes. After that I plan to epoxy coat the hull, taking care of any dings and gaps. Then paint and varnish and I will be ready to turn over. Perhaps 2-3 weeks.

How far along in your build are you?
