Subtitle:  ISAF Special Regulations, Section 3 – Structural Features, Stability and Fixed Equipment
Offshore Committee
Special Regulations Sub-committee

     

A submission from the A submission from the UNITED STATES SAILING ASSOCIATION

     

Proposal:

3.03.1 A yacht defined in the table above shall have been designed, built, maintained, modified and repaired in accordance with the requirements of either:

a) the EC Recreational Craft Directive for Category A (having obtained the CE mark), or

b) the ABS Guide for Building and Classing Offshore Yachts in which case the yacht shall have on board either a certificate of plan approval issued by ABS, or written statements signed by the designer and builder which confirm that they have respectively designed and built the yacht in accordance with the ABS Guide, or

c) ISO 12215 Category A, with written statements signed by the designer and builder which confirm that they have respectively designed and built the yacht in accordance with the ISO standard,

d) except that a race organizer and class rules may accept other evidence of suitability of design and build when that described in (a) or (b) above is not available, provided that the requirements of (a) or (b) have never been refused due to unsuitability of the boat. , when that described in (a), (b), or (c) above is not available,  the signed statement by a naval architect or other person familiar with the standards listed above that the yacht fulfills the requirements of (a), (b), or (c).

Current Position:

3.03.1 A yacht defined in the table above shall have been designed and built in accordance with either:

      a) the EC Recreational Craft Directive for Category A (having obtained the CE mark), or

       b) the ABS Guide for Building and Classing Offshore Yachts in which case the yacht shall have on board either a certificate of plan approval issued by ABS, or written statements signed by the designer and builder which confirm that they have respectively designed and built the yacht in accordance with the ABS Guide,

      c) except that a race organizer and class rules may accept other evidence of suitability of design and build when that described in (a) or (b) above is not available, provided that the requirements of (a) or (b) have never been refused due to unsuitability of the boat.

Reason:

The Offshore Special Regulations provide a series of recommendations for the construction and outfitting of yachts for offshore racing. If adopted by the race organizers in the Notice of Race, they become regulations for the race. Developed in response to accidents at sea, the “Special Regs” have provided an increased level of safety for those participating in ocean racing. The rules are reviewed and updated continuously as needed to reflect changes in design, construction or outside influences. A current rule however opens a loophole for inherently unsafe designs.

One of the longest standing rules establishes minimum construction standards. Although construction standards for yachts have existed for over a 100 years (Herreshoff’s, Lloyds, Lawley’s, etc.), it was in response to the 1979 Fastnet tragedy that the first set of rules were developed by the ITC for modern yachts. Published in draft form in the early 80’s and codified in 1986, these formed the Guide for Building and Classing Offshore Racing Yachts by the American Bureau of Shipping (ABS).  As with all ABS rules and guides, the regulations provided two levels of compliance. “Plan approval” constituted a review of the designer’s drawings and calculations by ABS engineers. “Plan approval with survey” also included the presence of a certified surveyor during construction to ensure that the vessel was built to the plans. Updated in 1994 in response to results from various round the world races, it was also updated in 1997. This last update was brought about by unfavorable legal action, where ABS realized that the risk versus reward for “classing” small craft with untrained crews was uneconomical. The update limited ABS plan approval to vessels between 79 and 100 feet. ABS continues to provide limited “plan approval with survey” for small craft at higher rates than is normally considered reasonable for small craft.

As the Special Regs required compliance with ABS, a system where the designer and builder certified that the vessel was designed and built in accordance with the ABS Guide was adopted. As these certificates were required to be inspected, the designer’s and builder’s professional reputations would be questioned if discrepancies were found. Although this caused some issues with older vessels where the designer had passed away, or the builder was no longer in business, those situations were rare. In rare cases of homebuilding, an independent engineer was required to evaluate the design for compliance.

During the late 90s the CE standards for small craft began to develop. The structural requirements were initially based on the ABS Guide and were later modified to take in to account a more accurate understanding of the loads and materials. An important difference with the CE standards is that a company or homebuilder, without any engineering background, can self-certify the structural design and construction. In the case of yacht building companies, their reputation is again on the line.

Two years ago the Special Regs rule reached its current form:

3.03.1 A yacht defined in the table above shall have been designed and built in accordance with either:
a) the EC Recreational Craft Directive for Category A (having obtained the CE mark), or
b) the ABS Guide for Building and Classing Offshore Yachts in which case the yacht shall have on board either a certificate of plan approval issued by ABS, or written statements signed by the designer and builder which confirm that they have respectively designed and built the yacht in accordance with the ABS Guide,

c) except that a race organizer or class rules may accept other evidence of suitability of design and build when that described in (a) or (b) above is not available, provided that the requirements of (a) or (b) have never been refused due to unsuitability of the boat.

The second section is the earlier ABS compliance route. The first section allows for CE compliance, which does not require any engineering background to certify the structural design of small craft (below 12m) or home-built craft. The third section allows for a race organizer to issue a favorable decision on the suitability of design and build of the vessel for offshore racing. This last option is very troubling. In addition to allowing the race organizers to take on a tremendous amount of liability, it allows for unskilled personnel to determine what is acceptably designed and built for offshore conditions. This could mean that a boat not suited for offshore racing would be allowed to race by well-intentioned, but unknowledgeable race organizers.

The implication of that loophole was probably not anticipated by the rule makers when the rule was initiated, but the result has been that boats not adequately built for offshore racing have participated in those races. For example, recently the new owner of a race boat asked me to look at damage sustained by the boat in an offshore passage. The owner wished to race the boat in the Newport-Bermuda Race and the boat had received trophies in two other offshore races. After looking through the boat I was suspicious that the boat did not meet the ABS standards. I contacted the designer and was informed that the boat in fact did not meet the ABS standards and had never been submitted for review. Nonetheless, the race organizers had approved the vessel for offshore racing. Luckily the damage was not severe. This was probably due to the fact that the previous owner believed that the vessel had never seen conditions worse than 30 knots and sea state 4.

The current wording of the rule allows for essentially “inshore” racing boats to race offshore. While the primary issue with this is one of insufficient construction and safety, the questions of fairness and trends is also important. If an older offshore racing vessel built to the ABS or CE standard races against an inshore design, clearly the lighter built boat will be more competitive (if it manages to finish). Once the word is out that to be competitive you must sail an inshore design offshore, the trend will be for lightly built boats to race offshore. That essentially means that the intention of the rule is bypassed completely.

An additional problem is the limitation in the rule’s preamble that the boat only needs to be “designed and built” in accordance with the standards, but not maintained or repaired. This has allowed modifications that compromise the yacht’s integrity.

To remedy this situation the committee should consider revising the rule to either drop option c), or to reword it such that it tightens the definition of suitability.  That could be that the design meets the requirements of an established scantling rule, or is checked by an engineer familiar with yacht structures. It seems ironic that a vessel is required to carry a large amount of safety gear, while the basic platform could be inherently unsafe. The 1998 Sydney Hobart demonstrated that the boats built to ABS came through with few problems, but that the boats not built or maintained to established standards could have significant problems. It also showed that simply doing the race numerous times before was not enough evidence to demonstrate that a vessel was sound for all the conditions it might see in the race. If the rule is not tightened, we could be looking at another wide-scale tragedy.
