I think Carl may be right. My wife's F15 requires regular tightening
of every nut and bolt so if this has not been done there is a chance
the forestay bolt may have loosened and allow water from the stay to
pass onto the deck and make its inevitable way sternwards.
However I wonder if the hatches might be an issue. If they cannot be
budged then it implies the enclosed volumes are airtight and so
changes in ambient temperature will create pressure in the stern space
and this might have resulted in a leak around the skeg. Take the skeg
out of the equation by sealing round it with easily removed silicone
sealant and it the problem stops, hey presto! If it still happens then
the silicone can be pulled off. I would they hard to get those hatch
covers off: I try to make sure both my and my wife's Filippis have the
hatches left slightly loose when storing to avoid pressure build up as
they are in a container that gets rather warm.
Also I suggest contacting your Filippi dealer: I have always found
them helpful.
All the best,
Richard
Oh, yeah... keep the screwdriver fairly near the hatch so you're
putting more of the force on the hatch rather than up near the joint
of the pliers where you'll be torquing the joint of the pliers... if
you try this method - if you haven't already figgered out a way to do
it..

Would some sort of penetrating oil--in the USA, WD-40 is the most
common--help free up those covers? Not sure if you want this kind of
stuff around shells, but gotta get those covers open.
Steven M-M
WD40 is widely available in many countries & is not great problem near a
boat, Steven. The only question is whether it will get into thread of
the hatch - if there's an O-ring seal, that'll probably keep the WD40 out.
Walter has the right idea for the hatch cover - superior leverage. And
I doubt the screwdriver's a necessary part of the kit. The pump pliers
(UK name), which are grips with the slip joint in which the pivot can be
moved to new positions when you open the grips right up, should be all
you need. Useful tool, anyway. Set the pivot position for widest grip,
hold the handles together so that position is held, engage the 2 jaw
tips one on either side of the hatch cover's central hand-grip & rotate
the grip handles anti-clockwise with modest force (don't want to rip the
thing out of the boat!). If that doesn't do it, then remove the fixing
screws, take out the hatch + surround & go to work on it on the bench.
When you get it free, apply Vaseline to the threads & the seal before
refitting the hatch cover into its surround.
A cause for the problem could be a combination of dry threads with
'stiction' of the rubber O-ring against the hatch surround being enough
to prevent unscrewing. One rather meaty operator fitting the hatches at
the factory & what goes in will not come out. Anything which has an
O-ring seal only needs gently closing to seal perfectly.
However, as I see it you probably have 2 completely separate problems.
I doubt there's water getting into the foot-well from the sealed
compartments or via bolt holes. I think it's splash over the saxboards
& drips running in off the wing rigger.
Maybe Filippi don't know the hatch can be a problem & would welcome a
heads up from the frustrated owner? We all need feedback.
Regarding the hatch covers: we have this problem with most Filippis,
the solution as discussed above is a set of pliers or similar device.
Tried and tested on every newer filippi my club owns.
I know people who have had to deal with a lot of these hatches have made
their own tools by making wooden levers with an appropriate shapes at
the end to fit the depressions in the hatch cover. Otherwise they are a
perpetual problem.
I would try wooden handscrew clamps if you have enough clearance. Tighten
the clamps and then turn them with large pump pliers. A custom tool cut to
fit would be even better, as you suggest.
Back to one of my earlier suggestions, starting with a question:
Are these hatches fitted with O-ring seals? The rubber has a high
coefficient of friction against moulded plastics that, once the hatch
has been closed, the frictional resistance acting along a seal perimeter
of ~300mm/1ft may completely defeat the unaided efforts of normal rowers.
In this case, a film of grease would probably reduce the friction enough
to allow easy unscrewing of the lid - at least for the first few times
after which you'd need to re-apply. If there's some other sort of seal,
or none, grease may still do the job as sometimes you get the greatest
friction in contacts between similar materials.
Wrenching off hatch covers as a matter of standard practice will not be
good for any boat.
You need a waterproof canoe sack - as per my suggestion above...
Sarah
Cheers for all your suggestions.
I'll first of all try and contact the UK dealer, again , I have
tried for the last 2 days, No answer so far, perhaps they are on
holiday.
I will swap boats with her for a while, so I can actually see this
water for myself.
It doesn't have a wing riiger, sorry I forgot to mention it has the 3
stay metal rigger.
Interesting about the water entering from splashes. This is possible
although she is very technically very good, one of these scullers who
can do mile after mile of square blades, makes yeah sick. I can't do
anymore than about 3 squareblade strokes in a row.
I will look at some sort of pliers(with a bit of protection) to see if
I can open the hatches and I will make sure she keeps them open after
each outing.
I'll get her a watertight bag for her clothes.
as above a word with the manufacture first, is the right way to go.
I'll let you know if we find anything over the next week or so.
Many Thanks Paul
This AM, I took a close look at the hatches in my 2001 Filippi 1x. The
unit is glued to the carbon bulkhead, so no unscrewing to take the
entire unit out. There are no gaskets in my older shell, so spraying
with a little WD40 might loosen things up. I wonder if the threads are
crossed; easy to do if you're not careful. I've never had a problem
with my hatches, but then again I'm the only one who uses this shell.
Steven M-M
Paul wasn't away this weekend just gone- was showing a new boat to a
prospective purchaser. (He keeps boats at our club). However, I am not
sure what the best way to contact him is I'm afraid
Just to confirm what you are saying, I seem to remember having been
told of an incident where a shell exploded. I think it was Ellen
Braithwaite who told me.
In any event, someone had forgotten to unscrew the hatch before tying
his shell to a rack on the roof of his car. I don't recall who it was,
or whether he heard the shell pop apart while driving, or if he only
discovered the shell in a disassembled state after he arrived at his
destination. But whatever happened, it must have been damned
unpleasant.
It also made a big impression. To this day if you are ever in
Sausalito and engaged in tying a shell to the rack on top of your car,
you are almost sure to be reminded to unscrew the port.
Until this evening I have always enjoyed the popping sound when I
unplug one of the triangular bungs on the beautiful Mary Elizabeth
Stone. But your post has made me wonder. Is all that "airtightness"
really so desirable?
Cordially,
Charles
It is oft remarked that the devil is in the details. But it is the
details that bring the story to life.
I thought that it was you who had told me the story and that the shell
was yours and that it had happened at the Tahoe Regatta. But I couldn’t
remember whether one shell or two were involved and if they had come
apart on the highway and you had heard them, or if you found them when
you were untying them from the rack.
In any event, the story is yours and I am glad you told it.
I wonder if it is really necessary to unscrew the hatch. Why not just
loosen it and remove the drain plugs at either end? Shouldn’t that be
enough to release any excess pressure?
I also wonder how important it is to have airtight shells in our
water. If we were sculling on fresh water, I don’t see how a tiny
amount of water inside the bulkhead would make much difference.
But we scull in salt water. And I cannot imagine that having a residue
of salt inside the bulkhead would be acceptable. One of the things
Carl told me when we were discussing buying the shell was that I must
be sure to rinse if off carefully.
At the time I seem to remember Carl’s saying, “The shell was made to
be rowed in water. A little fresh water won’t matter at all. But salt
water is another thing. Salt over time can cause a lot of damage.”
I cannot imagine any good coming from building up a residue of salt
inside the bulkhead.
Hope things are going well in Boston. Someone said you are out on the
water every day and training hard.
Good luck. I’ll look forward to more stories when you get back.
Warmest regards,
Charles

Nice one! But some rowers try very hard to do this without external
assistance. Again they do this becasue they fail to grasp that,
although a bit tight is good, extremely tight can be less good or plain
ruinous.
I understand that in Germany webbing straps with metal buckles are
mandatory, but I consider this unwise:
1. If the strap is not properly tightened, e.g. because a poorly
aligned loop can slide along a bar, then it can work slack.
2. Not all die-cast buckles are nearly as strong or reliable as they
may seem.
3. If a buckle has been trodden on or driven over (& both happen very
easily) it may be weakened or cracked.
4. Not all buckles hold as securely as they should, so again teh strap
can loosen
5. The overtightening problem
6. The wear that the hard webbing can induce in a paint, lacquer or
gel-coat finish
7. The lack of redundancy - if a strap goes, unless you had 2 in that
place you now have none.
For all those reasons I much prefer bungee cords, always used in pairs.
Any fool can buy a length of bungee cord and tie it into handy loops
of the right length to give good tension without causing damage. And
these will not go slack.
Carl,
Most of the bungees I see here in the USA are far too flimsy to
securely tie down a shell. Is there some weight or standard of bungee
that you would recommend for securing a shell.
Steven M-M
Good question, Steven -
It is not so much the weight of the bungee as their condition and the
number of them used at each point. I would not particularly advocate
the types already fitted with wire hooks. Although I do also use these,
I do so with a great deal of experience behind me and a lot of care at
the time of each using.
As I indicated, you can buy bungee cord (AKA shock cord) by the reel, &
you can get it in a range of diameters. It is available in a range of
diameters from ~3mm/0.125" to 14mm/0.55" and beyond.
For a single I'd recommend a complete loop of 6 or 8mm cord (tie the
ends with a thumb knot & slide one of those moulded nylon balls which
resemble pitted olives down over that knot). Ensure that you can get a
reasonable load (a reasonable load is not more than you can comfortably
pull over the boat) after you've looped it over from one side of the
car-top rack to the other, or looped it through itself on the trailer
rack & then over the boat to the other side. But you can always take
extra turns around the accessible end of the rack to be sure. And
always use 2 at each position - belt & braces makes perfect sense when
lives & valuable equipment are at stake if a boat breaks loose.
For bigger shells, go up a size or 2 on the cord diameter. Still use
pairs of doubled cords, at every racking position. And again adjust
tension by winding the accessible end around the rack to reduce slack.
But the vital rule is: _never_ use a significantly frayed or damaged
bungee. That said, a bungee cord has hundreds of individual rubber
strands in it so, unless you're using one with a lousy end hook, it has
a lot of redundancy & the first sign of fraying gives you time to get a
replacement.
One last point: singles are often tied down on a trailer at a point
where the only contact is with the deck ridge. It is easy to make a
simple V-block from wood, a bit wider than the boat at that point, & to
pad it with carpet. Then the tie-down load goes only on the deck edges
(sheer-line), not the centre or unsupported parts of the deck. It's
worth a few minutes of thought to preserve the health of a few thousands
worth of boat.
Cheers -
Carl
