Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities.

All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://webapps.mlca.uscg.mil/vdiv/specifications/feedback/defaul t.cfm

If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:

2. Arrangement will allow ship's force to perform maintenance on the small boat, without modification of the cradle.

3. Structure is manufactured using the most economical methods and materials available, and is capable of supporting the full weight of the small boat under normal conditions experienced during routine maintenance.

4. Contact surfaces are no harder or rougher than the contact surfaces for existing cradle onboard the vessel.

3.5.2 Boat accessibility. Ensure the storage is located in the vicinity of the vessel, and is unrestricted, to allow for ship's force to complete maintenance during normal working hours for the entire performance period.

Page 3 (REV 0)

3.5.3 Boat protection. Provide full protection that can be

safely and completely secured when the small boat is left unattended (e.g. watertight cover, storage in a warehouse or shop, etc.), in addition to isolating the boat from the elements.

3.5.4 Boat transportation. Transport each small boat to its

storage area within one week of docking the vessel and back to the vessel prior to the end of the performance period.

4. NOTES

4.1 Drydock terms. As used in these specifications, all

references to drydock facilities include graving drydocks, floating drydocks, marine railways, building ways or vertical lifts.

4.2 Arrival conditions. The Engineering Petty Officer (EPO)

will advise the Contractor of the actual tank and draft readings when the vessel arrives, and will discuss with the Contractor any ballast requirements necessary to accommodate the vessel draft and trim.

4.3 Paragraph number relationships. The paragraph number for

each subsection listed herein relates directly to identical sub-paragraph numbers in Std Spec 8634_STD.

4.4 Cutter Characteristics. The data shown does not represent the arrival displacement or docking displacement of the cutter.
