Around 400-450. I take a 5' 2 X 4 put the fulcrum. For me the ratio is
2.5. So if I just lift the tongue a bit when it is level on the jacks it is
pretty close to 400-450#. You can use longer or shorter 2 X 4's just keep
the ratio the same. Your ratio is of course based on your weight and the
tongue weight of around 400 to 450. You can use a log or a couple or
cinderblocks and a little triangle shaped strip of wood or I use a 2" X 6
inch piece of angle iron just to make the teeter totter, teeter.

Hey Graham,
Any Idea what the tongue weight was. If it is too light you will
get that motion even with breaks. I do several thousand mile trips on a
single axel with no problem. I do have breaks, electric are best for me.

I have an older RC trailer that does not have brakes and on one occasion the
trailer broke into a fantastic sway motion so powerful that it almost took
me off the road. I was going too fast but ever since I have been very
worried about towing the boat when the trailer does not have brakes.
Looking through the archive I see that one person added a second axel with
brakes and got good results both towing and stopping. Does anyone have more
details about how this might be done? Was the existing axel moved? Would
braking really be acceptable if the brakes were only on one axel?

Graham,
As far as the hull distortion while on the trailer; do you have the Triad
trailer designed for the Rhodes 22?. I believe Stan designed and had the
trailers made so the vertical bunk supports with the bulkheads. If not,
there are dimensioned drawings in the archives which can be used as a guide
to modify your trailer.

We have discussed the hull bulging while sitting on the trailer many times
previously. As you mentioned, it goes away once launched. Adding additional
support also adds weight and changes the characteristics of the boat from
the original design. I know of a hull where a previous owner attempted to
add additional layers of fiberglass to the hull. It didn't work very well
and during a bottom restoration every bit of it had to be removed. The new
owner had no idea his hull had been done that way.That being said, Stan has
made quite a few changes (most for the good) over the 40+ years that the
Rhodes has been his baby. When changes are made, thought as to total
structural integrity, weight and balance of the hull are always considered.
Simple fact, there ain't much wrong with a Rhodes. My hull is 25+ years old
and I still love to sail her It sounds to me that you purchased a project
boat and hopefully you knew that when you got her. Good luck and keep
posting.

Thanks Rummy.
Actually the hull is only a 74 and I know the earlier work by third party
contractors could be pretty bad. I don't know when Stan brought the work in
house and what he did to change the construction over the years but would
love to hear from anyone who might know.
I try to remember to mention the age of my boat and the fact that my
construction might well be inferior to latter model boats in my posts. So
thanks for making that important point. I don't want to alarm those with
newer boats. At the same time, those with older boats, if there are any
besides me, or those considering the purchase of an older boat might need to
be cautioned.
At the same time, being so old, there may be problems that take a longer
time to become apparent. It is not unreasonable to expect that any boat will
need some substantial reinvigoration after 40 years. It has held its age
better than I have. The boat has its problems but I still think that it is
worth the work to repair especially when you consider the cost of a new
Rhodes.
It seems like the chainplate construction hasn't changed over the years.
Does anyone know if the hull thickness has changed? When I removed the
kitchen and bulkhead I could see that the hull bulged in quite significantly
where the forward strut of the trailer bunk pressed on the hull. I raised
the boat on the trailer to take the weight off the hull and it seems that
the bulge is disappearing. I was considering reinforcing the hull with
additional layers of cloth since it is all exposed at the moment and would
be more inclined to do so if I knew that the newer hulls were thicker.
Does anyone know whether the deck construction and core material has
changed? Better quality plywood that was sealed with resin or epoxy and
bonded strongly to the deck would make a huge difference I would think.
It seems from reading other posts that the hull-deck join in some years was
dependant on screws alone. That would not be an improvement I would think.
The ballast arrangements and fill for the keel have changed a number of
times with some boats having cement poured on the cabin bilge in front of
the mast post and also in the keel. I can't say that I like that idea much
and am thankful that mine appears to be bricks of steel that are bonded to
the hull as well as a mix of what looks like lead flakes and a very soft
resin mix in the keel. At the same time the bottom of the keel appears to be
very weak and has developed a huge crack all around the slot for the
centreboard - something that no one else seems to have experienced. Mine was
not caused by grounding - not over the last 20 years that I have owned it at
least - so I tend to think that the fibreglass in that area was too thin.
Anyway, I agree with Rummy's caution that one should not assume that
construction problems of a boat of my vintage are present in other boats
without careful confirmation.. Nor should we assume that all changes
necessarily turned out to be improvements - especially over the test of
time.

Graham,
Just a caution here. Your hull if I remember correctly is a 77 model. Back
in those days Stan had other firms doing his fiberglass work. That's part of
the reason he won't recycle a hull that old. Many of the problems you
encountered are no longer problems with the newer hulls.

The picks might work fine. This is really a trial and error process. What
works partly depends on what the sealant is like. Silicone might come out in
longer pieces but other types are more tenacious and will probably have to
be cut or scraped out as it tends to crumble. The concave shape of the hull
makes it easier to get the tool in the slot. You might try protecting the
any visible surface with tape. If you try the hacksaw blade you can get a
plastic handle for a few bucks that will make life easier for you. I would
be reluctant to put anything in the slot that does not completely compress.
As that might simply hold the gap open. I think the trick is to get the
sealant way up inside and then compress the join before the sealant cures.
You will not get as good a seal if you wait for it to cure even though some
like Don Casey suggest a two-stage process of tightening it down moderately
until the sealant sets and then more firmly afterwards. Mind you, he is
talking about deck hardware where you have big bolts with backing plates
that allow you to apply heavy compressive forces. Others are very critical
of that approach and I happen to agree with them. I want the sealant to
spread out and fill all voids and I can't see that happening once it has
set. Neither can I see how the sealant will adhere to the surfaces once it
has set even if you could apply enough compressive force to make it spread.
When I removes the foredeck of my boat I was able to expose the hull deck
join and found that the sealant has been applied sparsely and with
significant gaps. If your boat is like mine, careful installation of the
sealant will produce much better results than the original. The hard part,
but most critical, is getting the old stuff out.
By the way, if you look at a cross section of the hill-deck join (see
attached photos) you will see that the plywood core at the edge of the deck
is exposed to anything that gets up the slot - whether water of bugs - I had
both. So the problem is not just a matter of a few splashes of water inside
the boat, it is also a matter of possible core rot and bug infestation. So a
good seal is important. Using a sealant with good adhesive qualities will
also strengthen the whole boat. The strongest is
5200 but that stuff is impossible to remove if that ever becomes necessary.
If it is done well, removal should not be necessary so it might be the most
permanent solution but the stuff worries me. It is another one of those
double-edged swords.
As an aside, you will also see from the photos that the plywood core
literally hangs on the outer skin with some kind of caulking and the inner
liner then hangs onto the plywood core. There is no structural support that
I could find. So, all of the downward force is pulling the sandwich
construction apart. Even the adhesive between the layers of the plywood had
given way. I hope that later model boats use better plywood. With flexing
over the years it can all come apart. When I removed the foredeck on my boat
I found that the caulking holding the plywood to the outer skin and liner
was very sparse and in places not even touching both surfaces. I could pull
the liner off and remove the plywood with my hands. Hence the spongy deck.
You can see the delamination in the close up photo. Of course this kind of
"fix" was extreme and ultimately was unnecessary once I knew what was
happening inside the core but at least it provides some photos of what is
under the skin of the deck for those who might have a spongy deck and are
wondering about the options to fix it. As you might guess, putting it all
back together was a major pain. I wish I had know then what I know now. It
would have saved me a ton of work. On the other hand I now have a foredeck
that is as solid as concrete and probably able to pierce a steel hull -
which is nice for a change.
BTW, I have a vent in the cabin top that once removed gave me a view of the
core at least in that area. It appears to me that the top is made much
better with a core that is over one inch thick. I saw no indication of
delamination, thank goodness.

Graham - thanks for the idea of wedging the joint open a bit wider to get
the sealant further in! Muireann definitely has screws that were behind the
rub rail mounting strip and, so far at least, no rivets that I've found.
Starting to clean things up. I'll try the hack saw blade, though I confess
some trepidation about damaging her paint. Also, our friends at Harbor
Freight have a four piece hook and pick set
(http://www.harborfreight.com/4-piece-pick-and-hook-set-66836.html) on sale
this month if your get their coupon book mailing. For $1.49 it may be worth
a try. The depth of the gap has me tempted to try to get something else way
up in the gap before trying to force sealant in. On Muireann it looks as if
the sealant was in general only intruded about halfway up the gap. I could
probably push something up higher to help serve as a further water intrusion
deterrent, maybe rope caulk, if that's still around, or teflon valve stem
rope. Heck, even 1/8" inch nylon or PP cording would slow down any water
intrusion that got by the sealant and maybe turn what would have been a
"squirt" from burying the bow into a trickle. Oh well, plenty of time to
think about that while I clean out as much of the old sealant as I can.
