Hello, I gave it one last try this summer but my surgically repaired back just will not tolerate trap work so up for sale at a reduced/very competitive price: 1991 Hobie 17 Sport (but includes boom) w/Spinnaker. The boat’s in great shape with carbon sails, 2 different sized jibs (sport and super), very new tramps, brand new EPO rudders/housings, etc., etc. Equipment as follows:
1991 Hobie 17 (white) - HIN#: ccm12757 Trailer in very good shape Masts w/tang for spin and also allows winch/block mast raising Aluminum spin pole w/SNU snuffer system Somerset carbon square top main run either boomless or on boom Harken traveller boomlet allows precise shaping of main Somerset carbon H18(super 17) jib Somerset sport jib in Code 0 carbon reinforced laminate Elliot Pattison Spin with SNU snuffer Main tramp & I sewed pouch on bottom for righting bag (included) Super jib tracks run full length of tramp w/ratchet blocks/cam Boat had thickened epoxy to beam socket gaps for slop free boats Lowered bow spreader per Murrays to stiffen boat EPO rudders w/upgraded Miracle connectors Wings (gotta love them) Upgraded harken blocks/travelers Beach wheels Hobie Bob Mast eye 6’ up mast for/w/dyneema side stays to create triangle and keep mast in line for winch/block mast raising/lowering.
I made a rigging video so I wouldn’t forget as my boats could be out of the water. You can find this on YouTube by searching Hobie 17 1991 rigging videl

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Intended as a single hander only.
Beam with wings: 11.58’.
Also available as a sloop with ‘sport’ package.
