Allen McClung has a picture of a Shoreland’r trailer being used to
trailer an F-21. Allen, what is the trailer model/specs? Can you
literally put your boat in the water and retrieve her with that trailer?

It is expensive having the marina put in and take out my boat, and I
think a trailer where I could do it my self on a decent ramp would be
great. Any info is appreciated.

Hi Peter,

I have a Freedom 21 sitting on a Shoreland trailer in my driveway with
about two feet of snow on it. Yet, you can just back the trailer into
the water and float the boat off it. However, I discovered that my ex-
Mercury Sable was not up to the effort. It needed a truck or SUV with
all wheel drive to pull it up a ramp. I have the shoal draft Freedom
21, so I can’t speak for what a fin keel boat on a trailer would
require.

Sincerely,

Thanks Max. I have a fin keel F-21, and an all wheel drive Chevy
Venture with the “trailer package”. As far as the van goes, I have
no trouble pulling around a camper. I plan on putting my boat in the
water at a dedicated dock space and leaving her there (except for
constant outings)all summer. However, $800 to have the marina splash
her bugs me a bit. I would probably use the trailer twice per year.
I’ve seen a few photos of F-21s on trailers, but the Shorland’r in
Allen McClung’s photo(with a fin keel) looks really elegant/simple.

Peter, Go to www.triadtrailers.com they made a lot of the original trailers for Freedom 21’s.I have a full keel and the trailer has 2 tongues.The one extends to put the boat deeper in the water.It is made from stuctural steel. The new models come with adjustable bunks.Warning, a new one can’t be cheap.

I have not rebuld my own trailer as I have a slip in a marina with a
decent ramp, but I have a bow roller ready to install to bring the nose
out of the water and I have two 12" heavy duty power boat rollers ready
for centering the keel. The bow roller will be placed faily far back
towards the keel because if the front edge of the keel hits the bunk
board at a faily sharp angle you will need a winch grinder from a race
boat to pull it up. The rollers will be angled in a V that is narrow at
the bunkboard so the keel will be centered automatically as you pull out

w/o something like that the boat will roll & yaw very easily as you try
to get on the trailer and if the wind blows the mast will do its best
to foil your efforts.

On a shallow ramp you will have to drown your van or get an extender
with wheels. On a steep ramp the boat will be floating so high off the
trailer that you will have great difficulty getting it placed correctly.

Early on I moved the bow hook down to get some lift - there’s lot of
glass there so that was easy and safe.

You really don’t need rollers instead of bunks - but make sure the bunk
boards do not touch the boat at the posts - The bunks are only for
keeping the boat upright. The keel can easily handle the load on the
shoal draft boat.

Note my bunkboards were “carpeted” which lead to rotting - I thought I
had punctured my boat, but I got lucky - the one and a half inch
bunkboard collapsed like a slice of wonderbread as we pulled out one
fall. Of couse that was the time my friend was driving clumsily - and
got uncivilized - not his fault many apololies and many beers later we
are still friends.

Biff,

I’ll check out the link. Thanks a lot. I’m new to the marina scene,
and I certainly like the personnel and respect the job they do but
wow, they sure want a lot of money for everything. Again, thanks.

Peter

Peter,

I had a fin keel (36") O’Day that I was able to launch and recover
off a trailer set up much less elegant/simple than Allen’s (I had 6
droppable side support stands with 8x8" carpet covered 2x8’s on top
of them). I just needed to find a steep enough ramp (more than 10
degrees, but less than 15 – to make sure that my boat and trailer
didn’t pull my van into the water) that went far enough into the
water to float me off the trailer. I had an extendable tongue on
that trailer, but I’ve seen people use a separate tow-bar type set up
to get their boat far enough into the water to work.

And, using a strong rig is a must:

Using the F21 fin keel as an example the boat and trailer weigh about
2200 pounds (1900 for the boat and 300 for the trailer). At rest on
level ground, the rig can be easily moved by hand. But on the ramp
the load increases according to this relationship:

Let w be weight rig on level ground, and
let x be the angle of ramp descent

hitch pull = w * Sin

For the case of a 2200# trailer on a 10-degree ramp:

hitch pull = 2200 * Sin[10]

= 2200 * 0.1736

= 365 pounds

That doesn’t sound like much, but if your Venture weighs (on average
as per Consumer Auto Guide) 3800 pounds, then it generates it’s own
down ramp pull of 660 pounds. So, you’ll need to pull an addition
1025 pounds (for a total of 7025#) just to move up the ramp.
Obviously those numbers go up as the ramp gets steeper.

So, if you can fine a moderately steep grooved concrete ramp that
extends far enough into the water and have the reach to put your
trailer deep enough at high tide, I see no reason to pay the marina
$800, but I’m cheap and stubborn.

Doug,

“Cheap and stubborn” are my middle names. Your math calculations
are terrifically helpful. My marina does have a steep, grooved ramp
right next to the lift. Without having checked for sure I suspect
the ramp is about as good as it gets if I have the trailer and the
vehicle to handle it. Let the money go to some trailer manufacturer
(once). What was the story with your trailer? Did it come with the
boat? Homemade? Custom made etc.? Thanks for the reply.

I have a Triad which has a about 6ft pullout extension to make it
easier, but I have not tried it . I pay about $50 twice a year but I
also pay storage all year round. I had always thought Triad was the
most common. I have been told that a trailer from a J 22 will work
well. Clyde
