Sailboat as powered cruiser?
 
Hi all....

This past summer I got to use a friends inflatable avon with a 4 hp
motor....and I really had a blast spending all day cruising around at about 4
knots in relative peace and quite and only using a few gallons of gas doing
it...of course that thing was about as hydrodynamic as cinder block....

It sure was the opposite of when I was a kid when and my Dad would take us on a
planing powered fishing boat, where we got beat to hell, went nearly deaf, got
soaked always, and burned gas/money like the Rockefellers.....

So, from my recent "cruising" experience, I've realized that slow and easy
could be pretty darn fun....and I could actually stand going so slow....so I
could cruise just for the sake of cruising on a nice day....or if I wanted to
dive or fish I could stand taking ALL day doing it (because of the slow
speed)...might as well since after a half day of fishing or diving Im so wiped
out anyway I spend the rest of day just vegging out.....so might as well vegg
out putting back to port in the boat....

Now, lets say I get the typical mostly enclosed small sailboat. Say 18 to 22
footer.

How many HP would I need to push such a vessel at hull speed? And say for
example that it calculates at 4HP, how much more power should I have in reserve
to fight wind, waves, bad weather, avoiding running the engine at max power etc
etc....

As an aside, around here...gulf of mexico, Pensacola Florida area...the ocean
weather is not often bad....when its bad for long periods of time you know its
coming and can avoid it....and generally if its something unexpected (ie pop up
thunderstorms) it only last a few hours at most...so its not like I'd want a
boat able to fight a New England type noreaster for days on end....and my uses
would most often be the bays, intercoastal water way, and the occasional ocean
jog 10 to 20 miles east/west of "the pass" and about 10 miles offshore max...

Would a sailboat (without any of the sailing thingamabobs on it) make a decent
day/long weekend powered cruiser when used in nice weather? And would it be
reasonably safe (if not comfortable) in bad weather (compared to a high powered
"normal" powerboat)?....

And would a sailboat in reasonably decent weather, say moderate swells, waves
or chop, be a fairly comfortable boat when at anchor? (I would think the keel
and its moment of inertia would help there)

And I certainly like the idea of economical boating being of a rather cheap
nature myself (and being poor at the moment makes for a really bad combination
:)....

Give the hurricane Ivan damage here, I could probably get a small sailboat hull
here for nearly nothing (hell, some are still in the trees in the
woods!).....amazing what a 40 foot storm surge will do!.....and a small
outboard is no big deal....but I imagine trying to rigg out a sailboat with all
the sailing "stuff" would probably make me faint cost wise.....

take care and dont get to upset with my blasphemous quest!

Any comments on the pros, cons, or possible gotcha's greatly appreciated!

take care

Hallelujah! You've seen the light!
Sounds like you'd be a very good candidate for a sailboat but I would
recommend taking sailing lessons. You'll have a bit more to think about
underway than a small powerboater.
I have a Sandpiper 565 which is 18' 6" long. It's a mini-cruiser with
accomodations for two adults (plus 2 small children)
and an MSD type of head with it's own holding tank and pump out outlet.
Most of these boats were sold with a 6hp Evinrude Yachtwin back in the
eighties and a trailer.
The beauty of this size sailboat is...
you can probably leave in your driveway on the trailer and avoid expensive
marinas
easy for two to rig, yet can be done singlehanded when setup properly
Since you only use the motor a fraction of the time, gas expense/noise level
minimal
If you need or want to, you can overnight....
good second hand models fairly plentiful at a rock bottom price (approx $
4K US for my model)
You get the 'right of way' while sailing..and the right to feel superior to
those gas/diesel guzzling environment destroying motorboaters. :-)

===================================

3 or 4 hp would push it to hull speed (around 5 kts) in flat water and
light wind. A total of 6 to 8 hp would be plenty for adverse
conditions.

Some things to consider:

Get the longest shaft that you can to minimize prop pull out on wave
tops.

Get a prop with at least 3 or 4 blades and a low pitch, so that the
engine can get up to speed and develop maximum thrust. They are
available for small OBs but it may take some shopping around.

While you are at it, get comfortable with sailing at the same time.
It's lots of fun and the ultimate in redundant backup systems.

Redundancy indeed...A friend of mine always said his ketch had 5
engines. One diesel and 4 sails.

anyway, a couple other things to think about - if you're talking about
a sailboat with no 'thingamabobs' as being one without the standing
rig itself....bad idea. if it's stability you're looking for, leave
the rig there, even if you don't intend to sail it. You'll be much
better off.

Also, learn to sail! If efficiency is a concern, you can't get much
more efficient than 'free fuel'! i.e. the wind! And it's fun,
rewarding, and frankly, will teach you a lot more about being on the
water than any power boat. Tides, current, wind, weather...right down
to the benefit of tying a decent knot etc...all become more apparent
under sail, and that knowledge does help you become a better overall
boater in my opinion.

Lastly, one thing to be said for the powerboat comparison you
mentioned r.e. bad weather...yes, a small sailboat will likely have a
'better' comparitive ride, but the small powerboat will probably be
tucked back into port while you're still enjoying that 'better' ride!

I don't know, having owned both - they each have their benefits, but
I'd have to say (keeping in mind I now own a 42' trawler) that I
enjoyed sailing that small Alberg 22' sloop as much or more than
running any of the other smaller powerboats I've owned.

Best of luck....

Presuming you really don't want to sail. You might want to look at small
trawlers. If you do not want to sail what you are really after is called a
displacement hull. And with a small engine they do cruise a long ways at a
modest speed and not using a whole lot of fuel. A sail boat is designed to
be efficient at sailing and if you're never going to sail you might as well
have some beam.

I think you missed some of BllFs6's equation. He's also looking for bang
for the buck, and as such I think he has a heck of a good idea.

There's a combination sailboat/powerboat called a McGregor (sp?) that
can be sailed or powered, usually with a 40 or 50 horse outboard. I've
seen one pulling a water skier. True blowboaters are apparently offended
when someone calls a McGregor a sailboat, but it has it's purpose, I guess.

I think BllFs6 has a great idea. A long range cruiser at a fraction of
the cost. Next he'll be adding a generator, another bank of house
batteries, new wiring, autopilot ... etc. etc.

Static stability, no. Righting moment, no. Moment of inertia, yes.

More weight higher up will reduce righting moment, as you cleverly
deduced, but it will also *greatly* increase the inertia in roll (and
pitch, for that matter, but the pitch axis is less important) and make
the boat more dynamically stable and a lot more comfortable.


I can't wait to hear this one.


Now you don't have to.

I sort of did this. Got a 25'er and since the wind only pushes it to about
3 mph I just use the 6 hp OB, which pushes it to about 5-6 mph.

2 strokes suck gas.

The ocean is NOT a pleasant place to be unless you're in a 60+ foot boat.
My boat bobs around like a cork on 3-6 foot swells, which are the norm in my
area. You can hardly go to the bathroom, you can't cook, you can't relax at
all. While trying to put the sail up/down I end up hanging onto the mast
for dear life while the boat flops around over the swells. There's no way
you'd get any sleep on the ocean until you've thoroughly acclimated yourself
to the constant throwing around. You will be hating life if you try to head
out on the ocean in a small sailboat and try any semblance of 'cruising.'
It'll take you weeks to get used to the noise and the bouncing at night, and
by that time you'll be sick of it.

That's a Really Good Idea. All other things considered (such as being able
to "run" to safe water) a small sailboat is MUCH safer and more
comfortable in rough seas. Even little 22-footers are capable of being
turned completely upside-down and they will right themselves.

As others have mentioned, start out with sails down as a powerboat. Then,
slowly, work your way into sailing: raise the main and get the advantage
of increased stability (and, if you trim it right, an auto-helm!) Pull out
the genny downwind and enjoy silent cruising.

Or, go completely power and remove the mast and have a swing-keel,
retracted.

7.5 should be enough, 9.9 plenty.

The McGreggor is an option, but for what they are, they're EXPENSIVE!
$30K CDN for a "bare-bones" 26-ft boat?? You can get a nice Catalina 22
for 1/2 that, and they sail better!

My Favourites in that size are the Cal/Crown line (as long as you're not
going to trailer them). Cal20, Crown 23, Cal 25. Not that great for room,
but they sail well, INCREDIBLY seaworthy, and you can pick up a used one
for $5K.

Or, you can try to find a Folkboat 25 with an inboard diesel, or a
Bayfield...

======================================

Righting moment is not improved of course, but roll resistance is
improved a lot. A sailboat with out its mast will roll gunnel to
gunnel in any kind of seaway. I once found that out the hard way on a
dark and stormy night off the New Jersey coast. Not a fun ride.

My experience has been that from the mid 40s on up is usually a decent
ride. I've sailed to Bermuda 4 times on sailboats 48 to 55 feet and
they were all fairly comfortable. My 2 trips on a light, fast 41 were
anything but.

A sailboat is not a very good platform for fishing and especially poor for
diving. Getting back in a sailboat with scuba gear could be quite a
challenge

That is pretty small! I would recommend a 25 foot boat as a minimum.

I would recommend getting as much as the boat can handle. You can always
throttle it back.


and generally if its something unexpected (ie pop up
thunderstorms) it only last a few hours at most.


If the boat can't handle the conditions you could be dead in a few
hours.....

jog 10 to 20 miles east/west of "the pass" and about 10 miles offshore
max...


Being close to the shore doesn't help you unless you can find shelter there.
Indeed, if the wind is coming from the ocean towards the shore being too
close can be a real problem. Being a mile from shore but twenty miles from
port still means you have twenty miles to go to get to shelter.



Would a sailboat (without any of the sailing thingamabobs on it) make a
decent
day/long weekend powered cruiser when used in nice weather?


A weekend on an 18 foot sailboat would be really cramped! At 25 feet two
people could be reasonably comfortable.

And would it be
reasonably safe (if not comfortable) in bad weather (compared to a high
powered
"normal" powerboat)?....


A sailboat tends to be very stable, and as long as you haven' t piled the
decks high with gear it could be quite sea-worthy.

Comfortable can be a different issue. In bad weather, you are going to get
tossed around. Some people can handle this fine, others get so sea-sick
they can't function. The boat can (probably will) leak and get everything
inside wet. Most small sailboats are tiller steered from the cockpit which
means you have to be out in the weather, which usually isn't too
comfortable. Compare this to a small powerboat that has an inside helm that
can keep you reasonably dry and warm.

And I certainly like the idea of economical boating being of a rather
cheap
nature myself (and being poor at the moment makes for a really bad
combination
:)....


Well, my first recommendation would be that if you are going to get a
sailboat, learn to sail! Think of how much more pleasant the cruise would
be if you weren't listening to the whine of that outboard and smelling its
fumes! Furthermore, in a decent wind you might actually make better time
with the sails then you could with the outboard. If the wind isn't
cooperating or blowing the wrong direction then you can fire up the motor
and cruise on in. It would also be safer, as you could always sail if the
motor died on you.

If you really didn't want to sail then I would recommend getting a power
boat that was built to go slow. A trawler or tug style boat would be just
your ticket, something with a displacement hull that could cruise along at 8
knots and not burn too much fuel doing it. The power boat will give you a
lot more useable space for a given length of boat and if you get a platform
off the transom it would be a lot better platform for diving.
