Action: We concur with this recommendation. The current stability booklet standard only<br />
provides a “pass/fail” approach and displays its information in a complex numeric format. The<br />
superior color-coded graphic display accounts for sea and wind state and shows the vessel’s risk<br />
of capsizing in stoplight-type colors. We will include a color-coded matrix for stability guidance<br />
in an update to Navigation and Vessel Inspection Circular 5-86, Voluntary Standards for U.S.<br />
Uninspected Commercial Fishing Vessels.<br />
Recommendation 11: The Coast Guard should review NVIC 5-86 to modernize the policy to<br />
reflect the changes in technology. Furthermore, the document should incorporate the MSC<br />
technical note 04-95 titled Lightship Change Determination; Weight-Moment Calculation vs.<br />
Deadweight Survey vs. Full Stability Test, which addresses weight changes triggering a new<br />
stability test for the vessel.<br />
Action: We concur with this recommendation. We will review Navigation and Vessel<br />
Inspection Circular 5-86, Voluntary Standards for U.S. Uninspected Commercial Fishing<br />
Vessels, and revise it to include, among other things, guidance from the Coast Guard Marine<br />
Safety Center’s Marine Technical Note 04-95.<br />
Recommendation 12: The Coast Guard should promulgate guidance addressing fishing vessel<br />
construction standards that minimize the free flow of water through a vessel.<br />
Action: We concur with this recommendation. Guidance regarding fishing vessel construction<br />
standards to minimize the free flow of water already exists in Navigation and Vessel Inspection<br />
Circular (NVIC) 5-86, Voluntary Standards for U.S. Uninspected Commercial Fishing Vessels,<br />
and 46 CFR 28.560. We will include this issue in our review of the NVIC and update its<br />
guidance as necessary.<br />
Recommendation 13: The Coast Guard should remove all provisions that allow the use of above<br />
main deck spaces in the development of a fishing vessel’s stability characteristics.<br />
Action: We concur with the intent of this recommendation. Incorporating the weathertight<br />
envelope in stability analyses provides an accurate measure of a vessel’s stability so long as<br />
operational practices do not compromise the spaces’ integrity. We believe removing the<br />
provisions that allow for the use of main deck spaces that are part of the weathertight envelope<br />
would be overly restrictive. However, there may be a need to amend the existing provisions to<br />
reduce the likelihood that the integrity of spaces above the main deck spaces that were used in<br />
stability analyses could be compromised due to operational practices or other factors. We will<br />
include this issue in our review of Navigation and Vessel Inspection Circular 5-86, Voluntary<br />
Standards for U.S. Uninspected Commercial Fishing Vessels, and update its guidance as<br />
necessary.<br />
Recommendation 14: The Coast Guard should review the significant alteration and major<br />
modification policy as it applies to fishing vessels and promulgate guidance for its consistent<br />
application.<br />
Action: We concur with the intent of this recommendation. The authority to make a<br />
determination of “major conversion” has been vested in the Coast Guard Marine Safety Center<br />
