Declaration of Conformity ISO 6185 for Coding

[offshore sea school]

I have a 2007 Humber Destroyer which I want to get coded. I need a declaration of conformity specific to the boat to show the surveyor. The manufacturer has given me a copy of a generic certificate for that type of rib but doesn't want to issue a specific one due to its age.

Is there any other option open to me here?

Speak to the surveyor. They generally aren't in the business of entirely scuppering plans and you may find the surveyor has come across a similar situation.

Many thanks will do

It will help your cause if you are aware of what you need to do for the coding. Surveyor's tend to be more willing to help if you can say to them "I've read the ISO and I've got x, y and z in place but I'm struggling a bit with a, b and c." It shows you are taking the coding 'seriously'.

This comes with a health warning as not all surveyors are the same and you may meet them on a bad day but I've always found if you make them confident that you know what you are doing, they are more willing to give you a favourable interpretation.

If Humber can't/won't provide an individual certificate, I'm not sure what your other options are.
At the beginning of the last coding of my boat (a 2005 6m Destroyer) the stability cert was questioned as the sister vessel used as the benchmark had twin engines (as opposed to my single). Humber supplied a stability cert that covered all sizes of the Destroyer for both single and twin engines, and this was accepted by the coding authority.
Speak to your surveyor and/or the coding authority, they're usually very pragmatic IME. There are many coded Destroyers out there so it shouldn't be a show stopper.

Also worth being aware that one coding authority and surveyor may not take the same stance as another( although following the same guidelines they of course should). May be worth shopping around if you can’t find what you need yourself.

Many thanks. my main concern is the transom height from the water where it curves down to hold the outboard. I'll find out more this week

I think if you look through the previous posts on the Commercial part of the forum, there is a bit on this. It seems to be solved by fitting an internal 'baffle'.

What engine(s) have you got? If it's set up for XL shaft you should be ok. You need minimum 250mm freeboard but if you can't achieve this, then a bund is the way to go (as has been suggested).
