Tickling briges with antennas....

Does anyone know the F30 bridge clearance? I can’t help out the F25
with the same question. Maybe somebody can help me. I think its
around 54’ but not really sure. I have never seen it in the specs.
(I suppose that some day I could try to measure up the component parts)

We are about to leave Maine to sail up to Bay of Fundy and St John New
Brunswick and then up the St John River which is a fine place to sail.
I am not truly worried; more like curious. I do know we tickled the
underbelly of the Jonesport (ME) bridge with out antenna at near low
tide (!) Not quite as bad as it sounds. Russell (dh) brilliantly
backed up to the bridge very gently under power so we could easily
pull away if we had to. Still pretty memorable…

I never actually used a tape to measure the total height of antenna above the waterline, but used 49 feet for clearance requirements on our F30.You can put the number together as follows: F30 Mainsail luff length (front edge) is 35 feet 3 inches. It would easy to measure from the tack, where the sail attached to the forward end of the boom, down to the water…and to eyeball the distance from the top of the headboard ring to the top of the highest masthead fittings (maybe an antenna). Total should add up to about 48 feet, plus or minus.Mauri Pro Sailing lists the sail dimensions of all Freedoms at:http://www.mauriprosailing.com/techinfo/boatspecs/Rig%20F.htmFreedom 25 luff length is 29.2 or 30 feet, depending on rig.One the other end of things, the draft spec from Freedom is often quoted as 4’
6". That number shows up in their lovely brochure for the shallow draft model. Our boat measured very close to 4’ 11" from the bottom of the keel to the bottom of the lower factory waterline stripe. Freedom cheated a bit on the numbers…(but otherwise built a great boat this is holding up very well…so I forgive them)Fargo ex F30 #12— On Sun, 7/27/08, Lola Jackson <lolaltd@…> wrote:From: Lola Jackson <lolaltd@…>Subject: Re: [FreedomOwnersGroup] Tickling briges with antennas…To: FreedomOwnersGroup@yahoogroups.comDate: Sunday, July 27, 2008, 11:19 AM

According to a 1987 letter from Freedom Customer Service,
height above water is 47’6”, not the 44” listed in the
original manual (wonder how they found that out?). Add the height of any
antennas, wind vanes, etc., to the 47’6”.

This one will make you say “Duh!!”

Unshackle the main halyard from the headboard and tie an adequate
length of braided 1/4" nylon line (or anything else of sufficient
strength) to the shackle.

Pull the halyard until the shackle is at the turning block at the
head of the mast, then secure the halyard.

Extend the remainder of the line in a straight line to the water at a
point even with the mast, then mark the line where the it touches the
water. Don’t pull hard enough to “tilt” the boat sideways during this
process. If the boat is already “listing” due to wind or weight
issues, go to the “high side” and tug hard enough to straighten the
mast to vertical.

Release the halyard, pull the block back down and re-attach it
wherever you normally keep it (you can mark the line where it enters
the “knot” on the shackle if you want).

Measure the length of the line after stretching it straight on the
dock or shore. Your line length will be the hypoteneuse of a right
triangle whose other two sides are equal to the turning block height
above the water line and the distance from the centerline of the boat
to the point at which the line entered the water…ignore it for
a “fudge factor” (it won’t be much) and add at least 1/2 the length
of your antenna to determine how much bridge clearance you need.

If you really want to be exact, the formula is:

The square of the hypoteneuse of a right triangle is equal to the sum
of the squares of the other two sides.

See my comment on the F-25 height above water. I believe the F-28
and F-30’s mast step is below the water line by a good bit. The
combined measurement should give you a safety factor with the bridges
Did you note the height of that Jonesport bridge when you approached?
Most bridges have scales on the bridge structure immersed in the
water that states the real-time clearance. If not, look at the local
chart for clearances Herm

The bridge in Jonesport, Maine has no markings and the tides vary from
9 to 12 feet there and we did not have a tide table for Joneport
itself (though we did for other ports not far away) so we had to
estimate the timing of low tide, though we knew the height of the
tide. I remember we were getting a little impatient waiting for low
tide and probably didn’t wait long enough. The chart shows the bridge
as 39’ which is mean high water, right? Lucky we only twanged the
antenna!

Wonderful to have an actual specification (47’6") for the F30. That I
will write in clear lettering in my photocopied F30 manual. To that I
will add something for the antenna and a generous fudge factor.

So true about not being able to tell by just eyeballing!

This whole discussion has been wonderful.
Thank you all. God willing, we are heading for St John River, NB on
Tuesday morning with adequate knowledge of necessary bridge clearances

I have been following the thread of this communication for some time. I can understand the uncertainty of knowing your vessel’s mast height and how to measure it. However, traveling away from home waters without a Coast Pilot and Charts, and without Tide and Current tables is not good seamanship. A short, uneventful trip can become a long, tension filled day.----- Original Message ----From: mbb05055 <mary.bigelow@…>To: FreedomOwnersGroup@yahoogroups.comSent: Friday, August 1, 2008 4:32:00 PMSubject:

We have essentially none. One does have to be aware of wind-driven
water-height differences, but these are not amenable to putting in a
nice chart. However, we have lots of thin water, and if you do get
stuck, you may have to wait for the wind to change direction.

Scott,
You really can’t call them tides then, can you?
There are places here in the northeast that get pretty
exciting during the ebbs and flows. Entering Woods Hole can be
pretty exciting. It’s the first place I ever saw a nun pulled
underwater by the current. I remember exiting York Harbor ME with
the tide. We asked for advice on how to get out safely and followed
instructions. We were told not to worry when the boat turned
sideways at the bend in the York River, “you’ll straighten out by and
by…” We did, but it certainly felt odd driving a sailboat sideways.
And then you’ve got the Bay of Fundy…
