The chief measurer's rulings 1 through 14 are included for purposes of showing historical
continuity only, since their intent has been incorporated into the current specifications
(January 10, 1987).
The rulings 15 and above are not included in the current specifications.
Note that Specification S-1.3 allows no modifications to Tanzer 16s that are not
permitted by the specifications, or by a ruling of the chief measurer.
-
Below Deck Halyard Cleats. Below deck halyard cleats
are allowed as an optional convenience item. (May 1972)
-
Cunningham Holes. Cunningham holes are acceptable
in Tanzer 16 sails.The basis for the ruling is that there is no prohibition of such
holes anywhere in the specifications and that, in principle, they allow the same
kind of adjustment as that which can be made by a downhaul, an already accepted
device in the Tanzer 16 specifications. Since the Tanzer 16 does not use black bands,
the only restriction on boom setting is that the level at the top edge of the boom
when projected to the mast shall not be less than 4'2" from the heel of the
mast. (August 1972)
-
Spinnaker Launching Chutes. Spinnaker launching
chutes are acceptable on Tanzer 16 yachts, there being nothing in the class specifications
to restrict their use. However, the Class Measurer feels it is not wise to cut holes
in the Tanzer 16 deck and recommends that if launching chutes are used they be closeable
to prevent seas breaking over the bow from swamping the boat. (August 1972)
-
Trap Door (Elvstrom) Bailers and Transom Flaps.
Trap door bailers and transom flaps are permitted on the Tanzer 16.They are not
specifically disallowed by anything in the Tanzer 16 specifications. Again the measurer
recommends avoiding cutting holes in the hull or deck of the Tanzer 16. (August
1972)
-
Below Deck Spinnaker Sheets and Guys. It is permissible
to run spinnaker sheets or guys under the decking of a Tanzer 16, there being nothing
in the specification restricting the running rigging for a spinnaker. Again, the
Class Measurer does not recommend cutting holes in the docks of the Tanzer 16. (January
1973)
-
Alternate Positions of the Main Sheet Blocks. No
alteration in the position of the main sheet tackle blocks will be allowed. Specifications
state that the main sheet tackle blocks must be affixed to the boom in accordance
with the official plans. The official plans show one block fixed to a bail 5'6"
from the forward end of the boom, the other fixed from a stainless steel strap at
the end of a 9'9" boom. The only alteration in block position allowed is dropping
of the center block when the sail is roller reefed. Other blocks attached to bails
anywhere else would interfere with the requirement that the boom shall be capable
of being roller reefed. (January 1973)
-
Jib Block Height Adjusters (Schreck Hauler). Such
devices are not allowed since their effect is essentially identical to Barber haulers
which are specifically prohibited. (January 1973)
-
Jib Tack Adjusters. Jib tacked to adjustable through
dock tension device is not allowed because jib stay tension equalizers are not allowed
and the tack of a headsail shall not be more than 2 inches from the deck. (February
1974)
-
Halyards. Hanging devices for jib halyard or main
halyard wires are not allowed because halyard locks are specifically prohibited
and no locking device aloft for halyards is permitted. (February 1974)
-
Slab Reefing. Slab reefing of the mainsail is allowed
provided the rig does not interfere with the ability to roller reef the sail as
required by class specifications.In addition, the slab reefing controls must not
be rigged in such a way that they can be used as leech line controls, which are
specifically prohibited by Article S-6. (March 1975)
-
Mainsail Measuring Instructions Mainsail width
at 3/4, 1/2, and 1/4 height is determined as stated in S-4-7, according to international
sail measurement instructions by determining separately the 1/4, 1/2, and 3/4 point
on the leech by folding each separately. “Cross-Measurements-- these shall
be determined as follows: the mid-point of the luff shall be determined by folding
the sail upon itself with the highest point of the headboard (1) nearest the luff
even with the lowest edge of the bolt rope nearest the tack. (2) The mid-point of
the leech shall be determined with the highest point of the headboard nearest the
luff even with the lowest point of the sail directly under the center of the clew
cringle. (3) The cross measurement shall be the distance between the mid-point of
the luff and leech. The bolt rope shall be included." Quarterway (and 3/4-way)
cross measurements shall be determined in a similar way by folding a second time.
(February 1974)
-
Mast Blocks Blocks inserted between the mast and
the mast opening in the deck are strictly prohibited, as they can function as spar
bending devices, which arc specifically prohibited by Article S-6. (March 1975)
-
Placement of Jib Sheet Track and Block No placement
of the jib track and block, or any other block, shall be so positioned that trimming
of the jib sheets can be made at an angle further inboard than that of the angle
from the jib clew to the track block as placed by the manufacturer. (August 1978)
-
Headsail Cunninghams Headsail cunninghams which
are designed to be unadjustable while racing and whose primary purpose is to prolong
sail life are permitted. (August 1986)
-
Paint A Tanzer 16 may be painted with any paint
that does not violate Rule 53, RRS, 2005-2008. (January 2005)
-
Sliding Mast Foot The foot of the mast and the
keelson may be modified by any means to allow the mast to slide easily fore and
aft, provided that the original elevation of the mast is maintained. (January 2005)
-
Halyard Material Wire halyards may be replaced with line
halyards made of any material. The intention of this ruling is to accommodate boat owners who need
to replace their old halyards by allowing the halyard to be replaced in the least expensive way,
without necessarily replacing sheaves or transporting the boat to a rigging shop
with pressing equipment. (Ruling date is unknown)
