Depth of centrecase bulkhead

[yimim]

I’m having a bit of trouble getting the tops of the centrecase bulkhead to line up with the top of the side panels, as they are protruding above it unless the bulkhead is modified in overall height. the construction guide talks about trimming the B/H to get a good fit, but this seems a bit beyond trimming, and I am having to keep rule 2.6b in mind

2.6 b. The depth of the centrecase bulkhead shall be within the specified limits when measured from the top of the keel to the top of the foredeck.

On this measurement, is the “top of the keel”, actually the top of the keel (line) at the bulkhead (since the keel timber doesn’t extend to the bulkhead), or does it actually mean from some point along the actual keel timber?

Sorry. I should have responded earlier. The measurement you refer to is taken from the keel. That is the outside of the hull. Just measure inside and add the thickness of the ply. It only refers to the centre so you can trim the bulkhead at the sides to come flush with the decks at the gunwale.

Hi csim,

I agree with your interpretation of rule 2.6b. It clearly states that it is measured from the top of the keel. I have asked the National MEasurer to check official templates to confirm the correct interpretation.

Ok, so rather than from “keel”, its from the keel.

Hi Harold – on another post you mentioned using Cedar on everything except the gunwale caps. Can you suggest the right cedar section for the side tank tops (rather than hardwood)?

Cheers
