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.
 

Boat Speed Calculator

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.
 

Sailing Articles

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.

Projects

Web development

This will be part of my portfolio, please feel free to contact me regarding web design/development.
