Boat Speed, boat hull, boat all sorts
Calculators for boat speed, definitions for boats like boat hulls, articles on Sail boat refit project, making your own bow thrusters, bowsprit and screecher, and info on cruising and sailing in general. I'll be writing about all things cruising e.g. survival at sea, boat maintenance, anchoring, interiors, DC electrics, hybrid electric boats, hydraulics, rigging etc.
Think of a small sailboat in a storm. Slow and determined, helpless, surviving
solely at the whim of Mother Nature, one rogue wave, one floating container… you got to be crazy. Riding the psycho snail, el loco caracol, la folie de l'escargot.
The site, it is to provide helpful tools and articles for sailing and boating in general. DIY how-to’s, help for fellow scallywags who intend, at some point, to drift away from civilization. Articles such as how to build your own bow thrusters, painting your topsides/hull, interior, working with closed cell foam, foam core layup, rigging a bowsprit, etc. This site will double up as my personal resume for sailing and web development/design with some
photos I’ve taken on my travels.
Calculations on
hull speed/
boat speed and power required for different boats
SL Ratio,
DL Ratio, using
boat displacement to calculate a
planing hull speed.
This calculator can be used to calculate
power boat speed as well as sailboat
speed, and calculation for the estimation of semi-displacement vessels, so the calculation are based on the
boats hull type because a
boat hull type impacts the type of perfornmace you can expect.
These calculations are based on
David Gerr's DL Ratio formula,
Wyman’s speed formula and
Crouch’s planing speed formula. Which use a combination of boat
hull displacement,
hull length at waterline, desired maximum speed and
hull buttock angle.
boat speed or hull resistance is the first step to calculating propeller size.
My intention is to sail across the pacific at some point in the future. I have bought an old Heavenly Twins 27 catamaran and will be refitting her for the voyage. As I go through the process of rebuilding the old boat, I'll post articles and photos of the various projects. I will not necessarily finish all of the projects listed because, as always, there are finite resources so many of the projects are, nice to have's and will be axed at some point. I will however post as much of my research as possible.
