TOM HOYE'S BENNET TWIN

DIMENSIONS: 5'8" x 21".
12" tail.
3 1/2" thick.
5-5 1/2" fins.

Soft low rails all around with a slight 'V in the tail and a slight concave in the nose.
The rocker is consistent throughout the board.
It's designed to stay on a consistent high plane - it's a little wider than the previous board for better flotation.
Basically it's a small wave board - 6' and under - built for long skatey turns and the positive feel of the twin fins.

JIMMY BEARDSLEY'S KEYO TWINFINNER


DIMENSIONS:
5'3" x 22".

121/2" chamfered back.
12" of 'V.
51/2" fins.
3 1/2" thick. (base)
ROBERT CONNEELEY CHINE

The Chine bottom is the next step on the hill.
George Greenough's gift to down under this winter.
The concept is cuting the roll out of the bowl of the hull, leaving two flat strips running down beside the centre plane and diminishing at the tail.
Thought the edge where the planes meet would bog down, but it does not if made right.
The extra flat gives more acceleration when board is on its side in a turn plus more initial speed at take off.
It seems to have all the speed of a low rail flat bottom yet the beautiful handling and safety for tube riding of the original hulls. This only my fourth shape job, made at Wilderness's beautiful factory in a very peaceful valley, convceived on the good vibes and love of my friends and prototype for my model with Hayden.

Dimensions:
5'9" x 20 1/4" x 9 1/4" square tail with a soft curve between the corners of the pod.

5 3/4" of nose lift, gradually fairing into a dead straight plane at tail.
A very soft S through the bottom trying about 3/32" of rise at back edge.
S through the botom (sic) trying about 3/32" of rise at back edge.

3 distinct planing surfaces on bottom and it is all driven by a very powerful 35 layer glass fin with about 3"-4" of flex.

Warren Cornish [Farrelly Surfboards]
The serious surfer today requires a range of widely differing equipment in order to give his best in the variable wave types and sizes found in Australia and indeed through­out the surfing world.
A five foot long wide tailed twin fin would be as ridiculous at Foresters at 8' as it would be at Waimea Bay at 30ft.
On the other hand a 6'6" semi-gun or 8' qun would be laughable at 2ft. Collaroy.
A wide range of surfboards are available from a few of the custom shops in Sydney.
Although not covering all wave sizes and forms, the three boards I have described be­low would be sufficient for most surfers to obtain satisfaction on 364 days out of the year.
Dual fin
Dimensions
5'4 ' x 20 1/2'' 'x 3 1/2" (1501b. surfer)
Outline
Smooth entry nose with no hip to hin­der water flow, running running into a straight drag free rail rear of centre.
Wide tail with rounded corners for smooth manouvering.
Profile
Flat plaining surface for rear 2/3 with moderate rise toward the tip.
Again smooth entry, rapid release.

Cross Section
Soft low rails predominate with hard edges only at tail.
Bottom is flat to concave through the centre and glat
(sic) at the tail, with a little cushion up front.
Some surfers may find a small V in the tail helpful for manouvering.
Thickness is carried right through to the tail area, with just a hint of S in the deck.
Fins
small    6"-7".
Placement is most crit­ical. Riged
(sic)
Surfing Characteristics

Designed primarily for radical turning manouveres in small to medium waves.
The dual fins allow a much wider, therefore more buoyant tail to be used than with a single fin (wide tails and single fins suffer from breakout during periods of high pressure applications to a rail.
The buoyancy prevents sudden stalling when wave speed drops as is typical with Sydney summer surf.
Turning arcs are short, forward drive de­creased.
The dual fin is ideally suited therefore to the short walled peaks found along the East Coast in Summer.
Its inherent stability enabling it to handle the most turbulent of waters it would be found wanting on a long walled Broken Head wave in its above dimensions.
A longer, narrower version however, is surfed successfully at Bells Beach.

Semi-Gun
Dimensions
6' 4" x 18" x 3" (1401b. surfer)
Outline
Generally a diamond outline with width and hip forward of centre.
Acceleration straight behind hip.
Narrow round tail.
Pointed nose for greater penetration.
Profile
Soft entry nose rocker running into a 180 deg. straight.
Cross Section
Low rails throughout, however they are not hard.
Three stage bottom - Flat under nose section, running through a concave centre to a large V in the tail.
Even thickness throughout with very little S.
Fin
Single centre fin 6"-7" deep.
Rigid with no flex, situated on tail.
Surfing Characteristics
Best suited to medium to large waves of delicate form.
This is a super fast instrument capable of long driving turns, and rapid accleration.
Designed for waves of the calibre of 8'-10' Foresters or Bells.
This style of board is responsible for the introduction of speed surfing with minimum water contact.
It is an unforgiving board de­manding the highest level of concen­tration to extract its potential.
Midget pioneered the use of this type of board in Australia.

Big Wave Design
Dimensions
7' 8" x 18" x 3 1/4'' (Built for Ted Dumuran, a 150 lb. Hawaiian)
Outline
Continual flowing curve form nose to tail.
No straight section in the rail.
Nose and tail are evenly balanced hav­ing a nose bias of only one inch.
The small round tail allows tight smooth manouvering.
Profile
Large nose rocker running into a 180 degree flat extinding for just under two thirds of the waterline.
The V in the tail has the effect of letting the rail line rise to the tail taking away the crankiness usually associated with long flats.
Cross Section
A very even thickness assures good balance and free running.
Rails are full in shape, for good running ability yet have'a very definite edge through­out the whole length of the board which keeps all manouvering positive.
Again we have a three section bottom with a large V in the tail, which has the same effect as tail rise without any of the latter's associated drag and stalling characteristics.
Fin

Situated on the tail.

Very upright pivot outline, 8 inches in depth.
Surfing Characteristics
This particular board was designed for Sunset which consists of a vertical peak requiring the surfer to reach the bottom quickly before the lip demol­ishes him.
From there it's a bank of the bottom requiring great acceleration and then a tuck into a long wall cum-tube requiring good reach. A stiff design pre­vents the surfer putting all this together quick enough, thus we soften the riding characteristics by shortening the planing surface or more correctly extending the forward cushion and cutting a deep V into the tail.
This would be a most successful design for Forester's Beef at 15 feet plus as well as big Bells.

Scott Dillon [Surfboards]
Scott Dillon is experimenting with fins again.
He did so a few years back, remember the tunnel fin and angled fins on Doc Spences' board.

This time he's back into the angled fins.
The board is 5'3" long, 21 1/2" wide and has a 12" back.
Scott is not suggest­ing that this board is any better than the twin fins the main thing he's inte
rested in is trying to take the thing a little further.
Paul Wright rode the board at Narrabeen on a small bumpy day and said that it came around faster and bites in well and said that he definitely felt like he was surfing on his backhand.

In California, Con Surfboards  offered two wide tailed models, the Fly and the Deuce.
Fitted with three fin-boxes, the rider could choose bewteen installing either a single or twin-fins (but not all three?).
1971
Tri Fin Further multifin experimentation, a central standard fin with two small 2" fins set forward on the rails. 
the original idea possibly concieved by Reno Abelleira (Hawaii).
Examples by Bob McTavish at Bennett Surfboards and Bros. Neilson.
 "In 1970 there were three groups of designer/shapers who were working on the three-fin idea," says Duncan. "Bob McTavish in Australia; Dick Brewer, Reno Abellira and others in Hawai‘i; and my brother and I." - Duncan Cambbell, quoted in
