Re: Mini hydroplane?

In competion hulls, a hydro class is faster than runabouts but most of these other boats who knows, alot would depend on how modern the design is (most are not) and the type of engine. I think Scott like all runabout people was just slamming the hydro drivers8)Bob

Re: Mini hydroplane?

Hi BAH,
Although runabout drivers may tease the hydro drivers, and vice-versa, there is a deeper respect that goes both ways. We like to josh each other a bit, usually after the final checkered has dropped and the coolers open up, and occasionally over a bonfire consisting of whatever boat(s) were wrecked beyond repair that day.
Anyway, what it comes down to is that hydroplanes take less work to drive.

A typical lap in a hydro consists of: Straightaway: hunching back and getting low, buttcheeks agains the clamp screws, throttle wide open. Into the turn: crack the throttle, burp the air from under the boat, shift your weight forward and the the left over the inside sponson, turn left, hook the turn fin and squeeze the throttle open again. Exit the turn: Straighten wheel, resume buttcheeks against transom posture and repeat.
A typical lap in a roll-up runabout consists of: Straightway: hunching back and getting low, right arm locked straight against the steering wheel. The bow starts to pop a bit, lurch forward, pushing down on the wheel. Repeat as needed until you get ready for the turn. Enter the turn: Throttle still wide open, hook right foot in starboard coaming, lurch body forward and to the left. Hope the inside chine hooks up and holds the boat from skidding as you grab a handful of steering wheel and turn. Throttle is now jabbing you in the ribs with every bounce of the hull. My God this is fun!! Exiting the turn: Slowly shift weight back against the transom, slowly let the boat roll flat again as you straighten the wheel and it accelerates out of the turn. Repeat.

As an analogy, driving a hydro is a bit like driving a sports car - fast with smooth handling. Driving a runabout is like driving an off-road Jeep. Not as fast, but a whole lot of fun in its own right.

I've driven both styles of hulls. It is a really neat sensation in a hydro when you're packing air under the hull and it starts to fly - literally. Your stomach kinda sags in your gut and the boat starts to hang out - you're really screaming! The sensation of pure speed is really quite thrilling! I have an "old school" Hedlund style hydroplane with a Mercury 25SS racing motor. It's no longer competitive, but it is fun to take out on a calm morning. 60+ mph in a 9'6" boat will get you going better than any cup of coffee... I've also driven a D-Stock Hydro with a Mercury Mark 55H racing motor - close to 80mph. I never knew a 4-mile long lake could get so small in such a hurry! But I really prefer the challenge of taking control of a runabout hull, feeling out the nuances of what makes it work, whether it be hooking it up in the turn like a water skier, or making it air out in a straight, bow high and loose, running on the ragged edge.

You'll have fun with either style of hull. And if you enjoy the process of building one, who's to say you can't try a couple of different styles. Try one this year, and build another next year. It's always more fun running with someone else...

Re: Mini hydroplane?

So what would one have to do to a hydroplane to make it turn both left and right?

Re: Mini hydroplane?

Thats the problem with a modern hydroplane as it rides the cushion of air under it you must hang the hull on a skid fin on the inside sponson to turn it if it had a fin on both sides it would turn both ways unfortunely with fins on both sire would cause the hull to tip on the outside fin causing it ot turn over, that is not very user freindly to say the lest and would hurt the hull and driver at sooner or later. That is why in ever day use a runabout is better

My dad used to make canvas kayaks. (still have the plans. gonna build another couple in the next few years) The canvas was coated in some sort of laquer and held up real well and looked dang good too.

Re: Mini hydroplane?

That's what is now considered to be a "round nose" hydro. I have an old Sid-Craft hydro of that style, although a bit bigger (Class C, running a Mercury Mark 30H). They aren't quite as aero-minded in their design as compared to a more modern picklefork style. They can still be plenty fast, though. Also, keep in mind that every hydro and runabout has their own little handling quirks. My Dad had a hydro that he simply could not get to plant and turn without hooking and spinning. He sold it to a guy who weighed about 40 lbs. more than him and he could get it to turn on a dime and return nine cents change. The boat just liked a bit more weight in the back to get it to plant and turn nicely. There will be a learning curve with any boat you decide to go with, so keep that in mind your first few times out.

The boat in the auction appears to be fairly well built, but in need of some TLC. Strip it down, seal it with epoxy (I would not fiberglass it as he suggests) and rig it up. Should be fun! If you wanted to get rid of the canvas deck, you might be able to use some door-skin type wood over the forward area. The canvas was a common way to reduce weight back then, before the advent of thinner plywoods and epoxy construction... Many boats these days use no fasteners at all - all epoxy. They'll use some staples to hold stuff in place 'til the epoxy kicks, then pull the staples. Back in those days they used a lot of WeldWood glue and bronze ring nails. Made for a heftier boat, which is not necessarily a bad thing for a weekend pond skimmer. I say go for it!

Re: Mini hydroplane?

How much would you pay for a hydro like that, basicly how much do you think i should bid before saying forget bout it

Hi BAH,
No more than $200-$250. There's no throttle, steering wheel or hardware to speak of. It needs work...
