How do you handle the boat single handed with no dock at the ramp?

What - you can't launch without a dock? What a wimp... :)

Simple, boat comes off the trailer, bow line attached to trailer, pull
boat to the side, beach same. The boat has a keel guard.

I guess I'm guilty of being a wimp then. I can't get on my boat
without having access to the stern, so beaching it at this time of the
year is not the best way to stay warm and dry.

I also don't have a keel guard and I have an aversion to scratching up
the nice shiny gelcoat.


I'm not used to seeing the tach so high and the speedo so low. At 5000
RPM, I'm touching 70 MPH, so if I saw that, I'd think my prop was
slipping or severely ventilating.....

It's not.

I know. It's just a radical departure from the "norm" that I'm used to
seeing.


Your boat was planing between 2000 and 3000 RPM judging from the shape
of the wake. My experience has shown me that the wake develops a white
frothy churn as it starts to rise up out of the water (about 2000 RPM
on my boat). The froth eventually retreats to a large "hump" almost
resembling a rooster tail just before fully on plane. As the wake
finally flattens, that is the point that you are officially
"on-plane". At that point your MPH will jump up sharply with a slight
rise in RPM (due to the load lessening).

Mine is pretty much the opposite. At 3k, the boat leaps up to 4k and
the speed goes from 20/23 to 30/35 and we're off to the races. It's
quite interesting to watch and experience.

See my post to DSK about the prop thing.

Your prop experiences are somewhat odd. Every inch of pitch should
change engine speed about 200 RPM. But more importantly, if the engine
is propped at the point where the sum of torque and H.P. are the
highest (Usually near the top of the rated RPM range), you should see
a greater speed than the same style prop with a lower or higher pitch.
It's strange that your speed remains constant while RPM is all over
the place. I would think you should see SOME difference in speed.

Also, higher rake props will add bow lift and allow you to trim
farther up, which should result in less wetted hull surface(drag) ,
and a corresponding increase in speed and RPM.

Setback engine brackets allow the engine to be placed in an area of
less turbulent water, which then allows you to raise the engine
height, and thereby reducing gearcase drag, which also translates to
higher speed.

I can slowly push my boat up to 3000 RPM and not be going more than 15
MPH initially. Once it goes "over the hump", the speed will quickly
rise to about 40 MPH, and the tach will jump to about 3400 RPM. When I
back it back to 3000, the speed will hold at 38 MPH. I can drop it
back to about 2300 RPM, and about 22 MPH with the tabs down before it
falls back off plane.

I can't hold plane much below 20.


I can't either. If not for the trim tabs, I wouldn't be able to go
much lower than 25. Then again, my boat isn't designed for slow
speeds.

Your boat is considerably different than mine - your wimpyness is
hereby excused.

For the nonce. :)

Tom, anticipating that you were about to post pictures of your stern
wave, I took a few of my own last Sunday. The one below was taken
about a mile west of Sanibel Island while traveling about 2 knots over
theoretical hull speed in a 60,000 pound boat. If you look closely
you can see two dolphins swimming in the wake which I estimate to be
about 3 feet in height at the stern of the boat.

These are the kinds of wakes I just LOVE to run into on Narragansett
Bay in my Ranger.

LOOOOOOVE them.... :)
=========================================

Yeah, you could get some serious air on that wake. Given what it
costs me to produce it, I should charge admission :-)

As it is I give everyone one free jump. If they annoy me in some way
and make a turn for a second pass, I just slow down a couple of knots
and take the fun away.

Later,


Inland lake sailors with the same boat as me..keep the boat a bit off shore
on the anchor while stowing vehicle/trailer. Then then wade/swim out to the
boat and use a boarding ladder.
The North Atlantic tends to be a bit cooler than inland lakes...so this is a
bit more uncomfortable.

And I should charge for the back and ankle pain caused from landing
after one of these sneak attacks. :)

I bet those lunatic PWC riders really enjoy it too.

Glad you asked...


I should mention ..it's a 1986 Sandpiper 565.

Neat little boat.

Thanks Tom. For two people...a snap.
I set it up for single handed rigging because my crew (wife) isn't 100%
reliable.
I installed a couple of small padeyes forward of the large shroud padeyes in
order to rig a loup. From these loups (starboard & port) I attach lines up
as far as I can reach on the mast. All for lateral stability during
raising.
I made up a 'gin pole' and a mast support pole to help also. Launching by
myself is tricky but doable.

Where there is a will, there is a way.
