I like to build it to sell, I was hoping it attracts international (ebay) buyers , honestly I don't think I can use it here either, just a test run that's it, but after visiting lake Ontario I can imagine a boat like this can be a blast in this area?
I used to live by the lake.... It would be a "toy" for anyone up there. You can't really boat but 5 months a year unless you are really into being cold. And the weather is very unpredictable. The lake can get quite rough with 2-3' swells not uncommon. There is a lot of $$ spent on sillier things up there though.

I could see that as a fast "commuter" for island or shore living. Hop in that and scoot down a river to the office. I don't think it would get me over to Savannah but it sure would make Hilton Head a short trip. And if it looks that good... who needs a Porsche?

Yes, it's a little bit like our RB18 or JA18:

It's fun as a picnic boat, to go to a waterfront restaurant on the week-end but that's all. Still, it is a pleasure to look at the boat, to build her.

Both boats have lots of potential for wow. The RB looks more stable though, but I don't know exactly what the hull looks like below on the Flyer. One of the joys of building your own boat (non-professionally) is making it very close if not exactly like what you envision. :) Within reason.... :lol:

Profiles can be seen better in the PDF (in post 1), pages labeled 31 and 32. Looks to be the equivalent of Jaguar race car. Say a 1955 D-Type Le Mans. May not be the most practical, but man o man that would turns some heads ....

Not wanna be pushy but I think my question got lost in the comments, so here's a bump 8)

Can you explain that a little more? I think it's more or less the same what the guys who are building tunnels in their hulls try to achieve or not? :doh: Should I put 2 holes (port and star) in the step under need the waterline and feed it air with hoses above the waterline? I tried to illustrate it in the pic at frame 9

The way I look at it: it's just a big piggy bank, loads of fun to fill, and hopefully I get out as much as I put in filling it :wink:

So this boat is a step hydro, popular before 3pt hydroplanes and tunnel hulls came about. A bunch of the water speed record boats from the 20s and 30s were built this way. Maybe you can find some videos on Youtube of how they run. With enough power I think it would run up on the step and not need ventilation, as it will skip along and can pull in air from the sides.

Some might think its sacrilege but a modern aluminum automotive 4cyl would perform great. Or even one of the new small 3cyl: http://jalopnik.com/why-fords-tiny-1-li ... 1543662936

There is a following for these types of hulls, and there is a big show in Mt. Dora & Tavares, FL every year where they are shown and sold: http://www.acbs-sunnyland.org/index.php ... 8-22-32-30 . I would think an original or restored historic boat would go for more than a modern reproduction, but it is just about finding the right guy with money who loves what you built.

Peter, I'll look at the lines tomorrow early.
My new drafter is out of the office today.
(It's my son, he surprised me with taking a drafting course and getting a diploma last year, he is really good with Rhino).

He has the Flyer in his files but did not work much on it: he is finishing the lofting of Atkin's Shoreliner for one of our builders.

Hi Matt thx for that suggestion found a clip of the boat (pic) I posted earlier which also is the same boat as the free flyer plans I belive.
https://www.youtube.com/watch?v=-FskmJM935Y, this clip really make me rethinking of building this boat.

Quote in the comment section
Engine in the video is a V.P AQ175 3,8L V-6. It only gave about 50% power, and managed 3000rpm. this due to a faulty carb.
Is it me, am I missing something or is this just a crappy unbalanced running boat? :doh:

That video makes the boat look bad. It may be a weight distribution problem or something wrong with the bottom.
Also, those small stepped hulls prefer to run in flat water.
peter, do a search on youtube and see this:

Much better but flat water and an enlarged version of that boat.
