This brings back some incredible memories. I ordered these plans from a boat magazine in the 1960’s. I was in 7th grade and my stepdad helped me build it professionally. Fiberglassed marine grade 1/4” plywood ($400 per sheet and two were required), painted it white with red racing stripes. We had a cabin at Donner Lake, so every weekend, my two brothers and I were on the lake racing ski boats. We could go about 45 mph and rarely lost a race. The swimming beach on the West end of Donner would constantly yell on the loudspeaker to “keep that damned hydro out of the area!” Back in the 69’s, $1,500 was a fortune for a school kid working. One of the great memories in my life with my dad.

Cool! I took over a plywood project boat as a kid, very similar, 9' 9" overall, 2-seater. I gave it fiberglass buckets, controls instead of the tiller, and a stock 18 HP Evinrude. Stern light with a jolly roger flag... Even had a speedo with a pitot, Learned that I had to lean over the bow to get it on step, but after that, remarkably stable. Took it on the Illinois River -- pretty close to suicide, with barges and 30' cabin cruisers, felt like a bathtub toy, but it could manage around 30 with two occupants. I've seen hundreds of kit boats on the internet, but never one like mine. Hard to believe it was a one-off design, though. I regret not photographing it more than once or twice.

So glad to finally see a video of a mini hydro with a seat. All the ones that I have seen have shown the driver kneeling on a PFD buoyant cushion. I'd prefer to sit down. But, from the video, I can tell that you would need to add some ballast in the bow and/or adjust the trim to keep it from porpoising.

Great boat. Runs really well. Bounce not bad at all. Hope you have been having fun all these years. 32 is real fast on that boat! zoom!!

My first boat was an 8 Ft hydroplane my brother talked me into buying. Bad decision by listening to him...ever! Then bought a ten ft racing roam with a new Evinrude 7.5 ((1957)). Then bought another new 7.5 Evinrude. I had a 10 footer with twins. A really cool boat for a ten year old living in Coconut Grove. GlennFHoward

It really should use a short shaft motor on it, and then trim the lower unit angle a bit. I had a 3 point hydro as a kid, and kneeled in it. Lots of fun.

If you move the seat forward about 3 or 4 inches you will greatly reduce the "hop" that the boat has. The center of gravity is a bit to far back. Do it! The ride will be far less rough and faster!

@@isaacbates8620 I like hearing the motor, the slap of the hull on the waves and other sounds of boating, not a music video. Creative elements can be other than music, such as composition and techniques that minimize wind noise or background music that doesn't cover up the sounds that make a boat video a boat video. Most "gearheads" want to hear the raw sounds; watching a boat, car, motorcycle, etc. and not hearing it is boring. Can you imagine watching Jay Leno and just hearing music instead of the car he is driving, wind or no wind?

@@isaacbates8620 i don't own, will never own nor do I ride a Harley, although I have done done work on them. I have an opinion and i know from other "music videos", where dozens of comments mirrored the opinion that the sound of the machine is what should be heard, that there are many that feel the same way. If no-one expresses their opinion, also known as "constructive criticism", then the author will never improve. I am not putting him down, just voicing an opinion on what I think would be better. if the boat was ugly, that i wouldn't comment on because how you make your vehicle look is personal. But, if I thought there was a way to do something in the build a better way, then I would mention it. I didn't put the person down, make snide comments or throw insults at him, just gave an opinion that I prefer to hear the "music" of the machine. If you like the music aspect, then make that comment as a rebuttal and part of a discussion. As a minor contributor myself, I get compliments and criticisms in the comments. I read them all and ignore some while using some to improve. That's how it works, ignore it if you don't want to change or change if you think a majority would kike the change.

Should do better than that I had an almost identical boat with an 18 HP Scott Attwater motor and it was much faster than that. Your boat is set up a bit wrong, and it is porpoising. Take the prop leg out a we bit more so it stops porpoising and you'll get more forward thrust.

absolutely no way. the engine new was rated to 4500, running a 2:1 lower, and figuring a 10% slip, you would need a 30" pitch screw to move water at 54mph. Ever see a 30" screw for a fastwin? Nope, neither has anyone else. Stock would have been a 9.25 or 10"

"A hydroplane (or hydro, or thunderboat) is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. A key aspect of hydroplanes is that they use the water they are on for lift rather than buoyancy, as well as for propulsion and steering: when travelling at high speed water is forced downwards by the bottom of the boat's hull. The water therefore exerts an equal and opposite force upwards, lifting the vast majority of the hull out of the water. This process, happening at the surface of the water, is known as ‘planing’." said wikipedia...
