Very nice! I like what you did with the chines. I'll have to search for the Devlin's book. Thanks for sharing.

At end of May and first of June I had a chance to take several short runs onto Lake Superior. On a breezy day with whitecaps I got kind of wet at the tiller. The future will involve a center console or other remote steer arrangement with a bit of shelter forward. Passengers mostly remained dry. Except my son and UP Tolman that one day? I think my hull weighs in at about 800 pounds. Largest loads were about 1200 pounds.Son advises our speed was about 22 to 23 mph according to the bicycle speed app on his phone, when he was willing to get it out. There were some bumpy times involving spray. Performance was adequate for me. I have more to learn and reflexes to acquire regarding boat handling. In the first photo the bow is pointed toward Isle Royale.

Back in Indiana last week we established that water skiing can happen with this set up. Had to consult with bumble bees on the physics of the situation, and meditate at length but it worked. Yes it was tough getting up with low power four stroke torque.  Once up it went all right. If budget allows I'd go for a little more horsepower.

AND thanks to the group for inspiration and advice.

Yooper,
Thanks for the ride! That's a great boat, I'm pretty sure I know what boat I will build next. Really goes to show how light these boats are, but I was even more amazed at the stability.

My jumbo is moving along, will be 90% painted by months end!

I like the toe grip on the stringer in the water ski photo, bin there.

Some fun developments. Found a 9.8 tiller lightly used. Checked on remote control upgrade of Merc 30 but a new Tohatsu 50 was just a "few" dollars more. Still doing break in.

Nice, is your main motor offset or centered.  I've been daydreaming about adding a kicker to mine in the off season, but can't figure out when that is down here.

Yooper,
Any performance numbers with this new setup? I am guessing its a huge upgrade since i rode along with you last.

Fishing has been unbelievable on the north side so far this summer. Too bad I am stuck south for now.

So far: it gets up to about 28 mph per gps at 6200 rpm, then will over-rev with more throttle.. Idles at about 2.7 mph  Will try changing from 11 pitch prop to 13 or 14.

Gets me up water skiing no problem. My friend's 29 year old son made it up on one ski on his second try.

The main is offset 9 inches to starboard. Snug fit with both motors in the 48 inch cutout, but not Nolan Notch snug.

My June time on Lake Superior was limited to motor break in, giving rides. I fiddled around a bit with a new downrigger and rod but got no serious fishing done.

Someone had a question about my reverse chines. This photo is intended to show the finished condition of the bow at what Devlin calls the transition joint. Hard to see detail being all black. This is shown in the second photo posted May 15, 2016 during assembly.

One other update, I ended up with a 13 pitch prop, it's just right.

This boat is good fun. Dogs love the water. We ski more than we fish, but when we fish it has been capable. inland lakes and Lake Superior. The main motor is now a 50. The boarding ladder fits where the 9.8 goes when we fish on bigger water.

Nice boat Yooper. Did you have to add width to the side panel layout as drawn in the book to accommodate the reverse chine? Would hate to cut out the side panels and have them not reach the sheer. I also like the concept. Several commercial hulls, like Intruder Boats in N.C. use that same section.

Yes I did cut the side panels generously wide, them trimmed them after the hull was assembled.
