hand board
hand plane/hand gun: originally a small (12 x 6 inches) timber board used as an adjunct by bodysurfers, often with webbing hand strap and used with flippers.
Since the mid 1970’s various plastic molded variations have been produced.
See The Pod # 205

hips
section of a board between the mid-point and 12 inches from the tail.

History
Order, purchase and ownership of the board; riders and contest results; repairs and / or restoration details.

Hobie Cat
Molded fibreglass asymmetric hulled catamaran designed by Hobie Alter and Phil Edwards (both USA) specifically for wave riding circa 1969.
This design was a huge world-wide success.

Hollow Board
1.first design 1926 by Tom Blake based on 16 ft ancient Olo board, and lightened by drilling the board full of holes then covering them with sheets of plywood.

This success, primarily as a paddleboard, was followed by the common hollow design of plywood covering over a light wood frame, with a bung.
Apart from competitive success in many paddling races, Blake ‘patented’ his design and published construction plans, e.g. Popular Mechanics, 1940, with the result that his design was used throughout the then surfing world.
This had definite influence in Peru (first surfers), New Zealand and Australia, firstly the Australian Racing 16 and in 1956 the construction method was used to make hollow examples of the Malibu board (Okinuee).
2. Hollow Wave, see below.

Hollow Wave
brand name, a molded epoxy honeycomb sandwich constructed hollow board circa 1973, developed by Karl Pope (USA), ex Morey-Pope Surfboards.
Available in seven different sizes or shapes.
Ridden and promoted in Australia by Peter Townend.

Hot Curl
1937 solid wood no-fin board with deep V bottom at the tail , credited to John Kelly, Wally Froiseth and Fran Heath in Hawaii.

Hot Dog (Board)
short, wide Malibu board with wide point at the centre.
Also ‘Sausage’ .

Hot Dog ( Performance)
fast, erratic style based on a maximum combination of turns, stalls and trims.
Most famously associated with Dewy Weber (USA) – contrast with Functional style of Phil Edwards.

Hot Dog (Ski)
short high performance finless surfski with seatbelt, developed by Merv Larson (USA) 1970.

hull
bottom.

Hull
circa 1969,Chris Brock / George Greenough design featuring chine rails

Hydrodymanic Planning Hull
Term used by Lindsay Lord, in his book Naval Architecture of Planing Hulls, Cornell Maritime Press, 1946.
who noted ...
1. "the differing performance between displacement hull (conventinal ships) and planning hulls when both are diriven at high speed.
Obviously, the submerged body, moving with sufficient rapidity, increseases the turbulence and the resulting suction drag, soon reaching a speed at which the viscosity of the liquid prevents further increase in speed regardless of practical increases in power.
For a craft " moving in it's own plane, this type of suction drag due to the viscosity of the liquid is not a factor in performance" - Page 12.
2. " With planning hulls, then, there is no theroetically sound procedure by which the total resistances of one hull can be directly compared to the total resistances of another hull radically different in size." - Page 25.
3."Unfortunately, airfoil or hrydrofoil data is of limited value...The boat's bottom operating at the boundary between two mediums, one of which is approximately 800 times as dense as the other, allows but one working face of the plane. " - Page 31.
It is important to note that while a surfboard is a planning hull as described by Lord, the submerged fin/s performs according to displacement hull principles.

Hydroplane Board / Stepped Tail / Scorpion (Tail)
circa 1965 Original design by John Kelly Jr. featuring a step in the board’s bottom profile behind the fin.
Some models were produced in Australia by King Surfboards.
Stepped bottom adapted by Ben Apia 1974 for his early model Stingers (see 422) with the step located at the forward flyers.
This feature does not appear on most interpretations of Apia’s design
