29 August 2022. Why a longer boat makes less resistance than a shorter if displacement is the same.

Racing boats are prestigius thats why builders of production boats copy them.
But racing boats are limited by rules and regulation especially concerning speed.
In other words the speed of a racing boat is limeted by racing rules.
Cruising boats are not racing therefore it is not rational to limit their speed by racing rules but this is whats happening.
I do not think thats a good idea. I do not limit the speed of my cruisers by racing rules. Therefore I make them slender.
If you want a sane boat do the same.
A bonus the become more seaworthy like whalebaots.

Sven Yrvind

Hi My name is Sven Yrvind. I design, build and cruise small boats. 1962 I left Sweden in 15 feet converted Blekingseka. I soon found out that there was room for improvement. To understand the basic I began to study mathematics and engenering. 1968 I sailed to England via many contries in a converted 13 feet rowing boat. People told me I be more happy on a bigger boat. November that year I found a wreck an old steam launch build 1885 I converted her to a staysail schooner and sailed her to Rio de Janeiro. That voyage advised me that a bigger boat do not bring happiness, happiness is an inside thing. I designed a 6 meter doubble ender built her in my mother basement. Tried to sail around Cape Horn with her but was capsized and pitchpoled. Later I built an 5.9 meter boat in her I rounded Cape Horn in the southern winter June 1980. I have continued to design, build, and cruise small boats often in high latitudes. Please support me on my donation button on my site yrvind.com
