A new Raidboat and Cruising Dinghy Design for Home Builders

Gonzo,

let's say each method has its advantages and both methods are quite fast. Holding the shape is one thing, but building a strongback and aligning the frames on it are another.

This thread has been shortened by the system , because it was deactivated over a year. I brought it back, because I met somebody seeking a cruising dinghy design and I wanted this thread to be a reference.

 

Hello Messabout:
from my experiences with dinghies ... double bottoms and side tank boats alike ... a cruising dinghy shall not capsise to 180°. It must be limited to 90° A self inflating boatsafer lashed to the mast is a must in dinghy cruising!

When at 90° its best that the boat sinks in to the centerline, so that its easier to grab the daggerboard and re-right the boat. Waterballast and defined places for heavy items and equipment near the bottom will help

When back to normal (000°) the greatest danger is if you have to bail the water out. The boat must be self bailing because: 1. you will be exhausted. 2. In 2' short waves the water will rush as fast into the boat as you are bailing it out. 3 The boat will be instable with half a ton of water inside and prone to re-capsise.

To get an impression ... Here is the video rambler re-righting his GIS and bailing out afterwards . In no waves and sunny skies. Imagine 2' waves and 25knots of wind.


Roger Barnes capsised his Ilur two times and every time has to be rescued by the authorities. He was not able to self rescue.

So, have fun, Michel
