Re: Boom position on a close reach

 

Greg and Caleb:

I really appreciate your comments.

I have done most of the things I could think of as you
are are correctly suggesting to flatten the and
de-power the main. This are the things I will like to
try next after given some thought to this issue and
taking into account your feedback.

1) In an attempt to flatten the main I had the vang
tight which as you pointed out is preventing the main
from twisting and spilling some air.

2) I should have also tried a first reef.

3) According to some of my readings our boat should be
able to carry the 176% Genoa up to 20 MPH so I had the
big head sail on. I was talking to a friend and he
pointed out that if I was not able to reduce the boat
heel I perhaps should have changed to the working jib.

He points out and I think he is correct that when the
boat is heeling it naturally has a tendency to point
higher because of the change in hull shape.

My thinking at the time was that the bigger head sail
would compensate and bring the bow down

3) As far as the rig tuning I will like to be able to
measure the stays tension. I do have some sag on the
head stay but I am not sure how much is acceptable.
any thoughts here.


thanks again for your comments

Re: Boom position on a close reach

 

Armando,
I have hull #328 and we experience some weather helm when close hauled as well.? One thing that can help is playing with the centerboard so it is better than half way up (eg., pointing astern) which brings the center of effort (CE) aft a bit.? We have been racing and close hauled and even use the traveler to center the boom on the boat.? There still will be some weather helm which will slow you down; each push on the tiller acts like a brake to the smooth water flow across the keel.?
I prefer to use the tiller incrementally, that is to only pull a little in the direction you want her to go and then let off the pressure on the tiller, and continue through a tack, than throwing the tiller hard to lee
Our boat will sail itself on a course a bit higher than a beam reach and we can actually modify the course by adjusting the centerboard.? Try this sometime in winds less than 15 as it is pretty cool when your boat will easily sail itself.? Also, as the wind increases you want flatter sails, rather than baggy, so using tightening the outhaul on the main is a good idea as is getting new a new main sail.
In terms of rigging and checking the pressure there is a device called a Loos gauge that somehow reads the tension in the wire.? A fairly tight fore stay and back stay will help the leading edge of the jib from sagging and will also add speed and better upwind performance from the sails.? Also to consider is that if it is blowing 18+ when you leave the dock you should put a reef in the main sail, the second reef point if it is really dangerous.? With one reef and a balanced furled jib we have been out in some stinky conditions (< 40) and stayed a lot flatter (with less weather helm) and still had full hull speed more comfortably.
Frankly though, a boat with lee helm is a much bigger problem than a boat with a bit of weather helm.? You always need to let out the main in big gusts and you can even adjust the jib accordingly when you see them coming.? But the T27 at roughly 3 1/2 tons can take a good bit of wind before the rail gets in the water.
I too have been grappling with the same issues as you and I still think the T27 is a great boat.
Odalisque came out of the Hudson River yesterday. Boo hoo.

People:

I got a few questions regarding balance of Hull 555.
I am experiencing a lot of weather helm when it gets
above 15 mph. I am thinking the shape of my main is
blown out but I am not sure.

1) Is there a procedure out there for checking
standing rigging setup that I could follow? By this I
mean stays tension and how to measure it, mast rake
etc.

I can hardly put the boom close to the boat center
line when close hauled and I am wondering if this is
normal?

In summary, on a blow this boat wants to round up and
I am fighting it all the time.

Re: backing plates

Greg Van Pelt
 

True that, Peter.

But Jamestown wants $280 for a 2x3 sheet of 1/2", which is the smallest
size they carry, and requires shipment by common carrier.

McMaster-Carr sells a 2x2 sheet of 1/2" for $108, and also has 12"x12"
sheets as well as 4" widths of 8' in1/8" increments from 1/8" to 1/2".
And no need for premium shipping.

In my experience, it's much better - read cost effective - to buy a
comparable product than anything that's labeled "marine" . . .

If there is a metal fabricator in your area that might be your best bet.

I had 12 backing plates made last year along with two replacement
centerboard pivot pins for $30.00

Oh and they also made me a new stainless centerboard at a cost of $800.

Re: deck paint and trailers

 

Hey Brian,

I just had my boat trucked in we launched on the ramp at my club. It
was a steeper ramp and the guy who hauled my boat had a Hydraulic
trailer and that was effortless. I know people who have put Pearson
30's on trailers from the same ramp but they had substantial vehicle
to pull it.

The mast can be a bear by hand and I really wouldn't do it unless you
have a rig that can lift it out by crank and several hands on deck.
You could do it with two boats parked on either side of you and use
their main halyards around your mast just below the spreaders with
lines led to winches but then you endanger other people, boats and a
whole host of issues. I've seen it done and I looked the other way.

Go to a yard and pay the money to have them at least unstep the mast
then you can deal with trailering on another day.

As for the paint? I used Interlux Brightsides on my last boat, last
August and I prepped, primed and took great care at applying it...
this past winter, where water or ice accumulated in the corners, It
peeled. Wasn't happy at all. My Tartan was painted with Toplac, an
interlux product, by the PO and it seems to have held up a little
better. I'm looking for someone who's also painted with something
and had a good response.

good luck.

So many posts about maintenance...

 

...a necessity with our older beloved pocket yachts.

However, ponder for a moment the pleasures our t27's bring. Here is
an anecdote and a reference.

Anecdote -

I was winterizing my T27, hull 47 (I think). Hatch closed and
mainsail off the boom. She looked deserted, but I was below. One of
the boat owners from the "fancy" dock (million dollar yachts) paused
by her and I overheard: "Sure is a pretty boat." It warmed my heart.

Reference -

If you haven't read: The Coast of Summer: Sailing New England Waters
from Shelter Island to Cape Cod (Paperback), consider picking up a
copy. It's a good and easy read about a man and his wife who sail in
their T27 along the New England coast. Many passages will ring
familiar. A good off-season read (but a poor substitute for actual
sailing).

Just taking a poll here.

It's painting time for my boat. I'm wondering what others have used
on the deck? My deck was repainted by the PO and it's coming off in
pieces now which is rather unsightly. A sure sign it needs
repainting is that I went to move the boat to a new marina and was
told the boat had to be repainted first. LOL. I guess that means
mother nature has done what she's gonna do.

I've also considered bringing my boat home as the antifouline and
topsides also could use new paint. It would be *much* easier for me
to do it at home where I have space and tools. What type and
capacity of trailer are others using? I hate to say it, but I'm a
tad intimidated by trying to figure out what sort of trailer is right
and getting the boat out of the water. That said, I used to have a C-
22, so Its not the trailer, just the hassle of finding one that will
work.

Can a flatbed with cradle be used? I am almost certain that I'll
need to have the marina lift her out and unstep the mast. It seems
like it would be a monster to unstep by hand or to try to recover her
on a boat ramp. Any thoughts? We do have one or two "deep" ramps
that were suitable for the c-22 (which draws 1.5ft). I doubt that
they would fly for a T-27. And it's not like I can power her on the
trailer. lol.

Free Tartan 27

Richard, you are fast, I just posted it on Craigslist Boston.

I am posting this for a friend as I already own a T27 and don't need another.
The boat is sound, I checked it out before, but it is a project boat for sure. If you have the
time and skills to restore it, it would make a great project. Or if you have a way to dispose of
it, you can bring it home and strip it for parts including the Atomic 4.

Anyway, don't shoot the messager. May be this is exactly what someone is looking for. Ever
read the book "Fix It and Sail"? It is free for the taken, just not free to restore it to sailing
condition : )


Free Tartan 27

 

This just popped up on Craigs List...

Of course There is no such thing as a free boat...
