Downflooding angle

[TeddyDiver]

Allthough I don't have to, with my self engineered boatplans to get CE plates on the boat, I still like to do things properly. I've been now calculating STIX and got a question concerning DownFlooding Factor. What kinds of hatch/opening/companionway/door is considered secure or nonsecure in this regard???

I would also preciate the formulas for Roll Period and Roll Acceleration

You will find the down flooding in:
International Standard ISO 12217-2 reference number ISO 12217-2:2002(E) Small Craft- Stability and Buoyancy Assessment and Categorization
AnnexB (Page 29) Methode for Calculating Downflooding Angle.
The ISO booklet is not cheep, the 60 pages booklet cost $180.00 if I remember correctly. must be higher now.
Good luck

Going to other thread Sailing boats' Stability, STIX and Old Ratios
It's allready about the subject..

[dskira]

So you just have just to buy the booklet and I will have the real thing since the CE regulation is ISO standard.
Good luck

I'm trying to find out, if references like mentioned here, are included in the booklet or not, and do they contain any information about watertight doors. Nothing against buying books but in this respect I'm trying to find out which standard includes, if any, the information I'm looking for. So far it looks (by the names anyway) like the last one (ISO 11812) could be the one?

"2 Normative references

However, parties to agreements based on this part of ISO 12217 are encouraged to investigate the possibility of applying
the most recent editions of the normative documents indicated below. For undated references, the latest edition of the
normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.
ISO 2896:2001, Rigid cellular plastics – Determination of water absorption
ISO 8666:–1), Small craft – Principal data
ISO 9093-1:1994, Small craft – Seacocks and through-hull fittings – Part 1: Metallic
ISO 9093-2: –1), Small craft – Seacocks and through-hull fittings – Part 2: Non-metallic

ISO 10240:19952), Small craft – Owner’s manual
ISO 11812:2001, Small craft – Watertight cockpits and quick-draining cockpits"

So are these in the same book?

Teddy,
ISO norms are sold one by one, not in a book. You just have to buy whatever ones you need, but only those. Regarding cockpits and doors you need:

ISO 11812:2001, Small craft – Watertight cockpits and quick-draining cockpits
ISO 12216:2002 Small craft - Windows, portlights, hatches, deadlights and doors - Strength and watertightness requirements

Please find attached the last available version of the RSG Guidelines, which are of interest to apply the RCD.

Cheers.
