Bennet Norman Launches His New Albion Power Dory

Bennet Norman just sent me these pictures of his Albion Power Dory. He stretched it to 21 feet and widened a bit also from the plans. It looks like it flies with 115 hp jet drive, and he says it runs just great.

Wye River Garvey with Jet Drive Launched in New York

Jason Thompson has been working on a Wye River with a jet pump and tunnel. He's building it in New York. He tested it over the 4th of July weekend, and sent me this note and pictures.

Good morning Jeff,
First water test results are fantastic. With 4 people in the boat handling was excellent, and top speed was 34mph. With 2 people in the boat top speed was 37mph, and handing was very good.

Those tests were on a lake, so I took it to the Chemung river, where I intend to run the boat most. Beautiful. At speed, 4 inches of water is no problem. I definitely need to be moving forward at good speed for that depth, if I'm not, the jet pump sucks the rocks up from the bottom of the river. At speed, this is not a problem.

I'm moving forward with the glassing, and the interior of the boat now that I know the concept is working.

Thanks again for the plans,
Jason Thompson

Homebuilt Grander Whitewater Dory in the Grand Canyon

I received this email and pictures just yesterday.

Dear Jeff,
Several years ago I wrote to you asking for a double ender whitewater dory design. Within a year a design was out for the Grander. Two years I finally had the time to undertake the building of the dory and the space to build it. Wow! What a year it has been. It was a daily learning experience. I stopped working on the dory at least twice simply because it was more than I could do. With encouragement from friends and a friend who put in many hours, I finally finished the dory two weeks before my Grand Canyon launch date: March 22, 2017.

Take a look at her and realize she (Zenah) was the best dory a person could use to run the Colorado River through the Grand Canyon. Zenah took on the biggest holes and grandest wave with ease. I never thought during the entire 235 mile trip with a hundred plus rapids that she would fail me. What an incredible design and awesome dory. Lava Falls is one of the biggest rapids on the Grand, the pictures will give you an idea of the wave size.

Thanks,

Dale Holt Houghtaling

235 miles and 100 rapids? Wow, what a trip that must have been. So happy you enjoyed it and the dory!

Seneca Pacific Dory Completed in Washington

Just got this note from a builder in Washington.

Hey Jeff,
I just completed the construction of a 14 foot Seneca pacific power dory. I started the boat in October and finished up on Easter. Since then, I have used the boat three times in Lake Washington near Seattle. The construction was definitely more work than I thought but I ended up with a great boat. We placed a 15 horsepower motor on the boat which pushes it along well. With one person you are flying across the water but once you get up to three people it slows down a lot. With two people, I could get the boat going about 16 mph. I would like to potentially get a bigger motor. The Seneca cuts through larger waves well and is quite stable. The boat building experience was great and I would like to continue it in the future.

Thanks for all of your help!

-Will.

Boatbuilding Pictures

Boat Building Photos

Please don't be embarrassed to send in photos of your projects. I get a lot of emails from people who tell me about their build but never send any pictures. I'd love to see them, as would all of the other people who are either building a boat or thinking about it. They need all the encouragement they can get.

I believe in offering you all the information you need to learn more about how to build a boat. That's why I offer free videos, free ebooks, and free reports. There's even some free plans available to isiders and some seminars I've delivered. To join, just click below:
