Downflooding

[C08]

Jazzcat is more stable upside down than the right way up, but short of that, downflooding isn't an issue. Yes, if we did heel to 90 deg, it's likely the forehatch would fail, allowing water in, but we wouldn't stay that way for long, so that would be the least of my worries. Fortunately, I am unaware of anyone who'd succeeded in flying a hull, let alone capsized a Catalac, and I believe it's never been done.

8M Catalacs are prone to downflooding in certain circumstances. I anchored up a steep beach and dried out. When the tide returned with some wave action the rear port locker filled through the locker drains and before the boat floated off filled the port cockpit locker and thence the port cabin bilge through the steering cable holes so the wooden cabin bilge covers were floating when I returned to the boat the next day. I suspect another tide with the locker and bilge filled may have sunk the boat but fortunately I returned before that happened.

The 'confessional' above by CO8 is valuable, reflecting the good intentions of the MAIB's Safety Digest and the 'CHIRP' ( Confidential Hazardous Incident Reporting Programme ) protocol. These allow owners/operators to 'flag up' incidents so that others ( us ) might learn summat and avoid a costly repetition.

Perhaps there might be space made in here for such an activity, if the mods and admins thought it appropriate.

It must have been a really steep beach, but thanks for the warning. I'd be in deep doo-doo if that happened to Jazzcat, because my engines are on those cockpit lockers, but perhaps that might be an advantage, as the weight is further forward than with an outboard or single engine

My simple fix for this situation ( and strong following seas) is boarding over the corner with the steering cable using sealant and having a sloping small "roof" over the corner at the top. It all pulls away to oil the cables and gives me peace of mind.
