Re: Stus-List C and C 25 water in lockers under settees, Now Stability

The stability graph has three C 25s listed.
A 25, a mk1 and a mk2

When was the 25 built (as opposed to the mk 1) ?

Re: Stus-List C and C 25 water in lockers under settees, Now Stability

That stability graph definitely shows the 29-2 as tender. 

However I could wash the windows on the 25-2 if I had a mind to. I also
owned a 33-1 which, when we were racing, would have the person responsible
for helping the genoa around when tacking, ankle deep in water if the wind
was up and they were slow in getting off the low side. I don't see the 33-1
on the chart.

I'm reluctant to argue with a proven methodology, but I find the 29-2 to be
both stiff and forgiving compared to the other 2. To me the 29-2  heels to a
certain point where the rail is still not buried  and then says you really
should do something with the main and if you don't  it will start to round
up rather than continue to heel.  Is it possible that this behaviour is due
to the hull shape and this is not captured in the stability test which is
static. If so that could explain why the boat is rated as tender, but will
only heel to a certain point in real world conditions.

I experienced this occasionally when I had a C 25-2. It would only happen
when the sailing hard to weather with the rail buried. If I were going to
tighten the hull/deck joint screws I'd start with those closest to the
chainplates.

 

This is not an issue with the 29-2 as it is a very stiff boat and doesn't
appear possible to bury the rail.

That graph confirms my experience on our 30-2. We flatten and reef early.

Stus-List C and C 25 water in lockers under settees

[Bmue via CnC-List]

Hi Mark 
Did you figure out where the water is coming from?
We seem to be having exactly the same problem. During the deck restore the 
seeps we used to experience occasionally during rainstorms were fixed. Now we 
sometimes find water in the settee lockers during/after sailing. it stays there 
as there is no connection to the bilge (which has occasionally some water in it 
but nothing to worry about.)
I crawled around inside the boat trying to find any seeps while underway and 
found nothing along rails. 

Any ideas?
 Is there a schematic available that shows how the settee lockers are connected 
to the rest of the boat?
 Did you drill drainage holes so the water can drain into the bilge?

have water in each of the aft storage bins under the settees. When it rains no 
water accumulates, but when we go for a sail there will be a small amount of 
water in each bin. After I dry it out, it stays dry until we go for a sail. 
What I'm thinking is there is a leak in the seal in between the topsides and 
the hull seam, and sea spray forces its way into the hull on the down wind 
side. I was thinking that I need to tighten the bolts along the toe rail that 
hold the topsides to the hull. I've read online that you hold the screw steady 
on top and turn the bolt underneath. I believe there is butyl tape in between 
the hull and the topsides. I was thinking of giving each bolt a 1/4 turn. Is my 
thinking on this correct? Thanks a lot for your help.
