Speedy sponsons

No that wouldn’t be one of ours We have only built hydros

Additional history on Edison inventing the light bulb vs Swan on the same:

"Or did he? It’s painful to cast aspersions on the reputation of one of America’s heroes, but Edison, who patented his bulb in 1879, merely improved on a design that British inventor Joseph Swan had patented 10 years earlier. Swan sued Edison for patent infringement, and the British courts ruled against Edison (as punishment, Edison had to make Swan a partner in his electric company). Even the U.S. Patent Office decided in 1883 that Edison’s patent was invalid, as it also duplicated the work of another American inventor."

Edison improved it and commercialized it (credit due) and had the news media at his disposal to report and build his reputation. He did some despicable things with killing animals in the War of the Currents of his DC against Tesla's AC. Look up that one.

History does not happen in a linear way but it does rhymes at times.

Start the bagels and cream cheese ;-)

I like that we've covered sponsons, bagels, light bulbs (I'm going to stretch that a bit into heated filaments in a toaster). If you put that all together we now have a great morning set up of a nice breakfast with a toasted bagel and the kitchen lights on low. Followed by some boat testing. Sounds like a good day. I think I'll do that this Saturday.

By October 1879, Edison's team had produced a light bulb with a carbonized filament of uncoated cotton thread that could last for 14.5 hours.
Several months after the 1879 patent was granted, Edison and his team discovered that a carbonized bamboo filament could burn for more than 1,200 hours. Bamboo was used for the filaments in Edison's bulbs until it began to be replaced by longer-lasting materials in the 1880s and early 1900s.

Right, great to try stuff and experiment and modify. BTW Edison did not invent the light bulb he perfected the filament with hundreds of employees working on the 1000's of possibilities. Credit to others before like Warren de la Rue in 1840 then J. Swan in 1850 when Edison was 3 years old. Edison commercialized it. History could use updating. Like Marconi inventing the radio it was N.Tesla.

Glad to hear you're going ahead with your, or your uncles idea. To many times we get caught up in saying "what if", what if is a silly game, go forward if it don't work, you learned and move on.

Bud….. you are exactly correct…. when Thomas Edison was inventing ‘things’ and someone would say…’You failed 1000 times’… Edison would reply…’No I didn’t … I just learned 1000 things that did not work’. This was for sure when he invented the light bulb… he tried I think 1000 materials before he tried tungsten for the filament.

To me it’s fun building something a bit different based on things that are talked about when we race on land while in the shop I currently have two identical boats in my shop one built with a very aggressive s bottom design that we believe will work and another with all the same measurements but a conservative bottom design the same as most would see on a bezoat c hydro so we are excited to see the comparison

Only 1 Carruthers in the CBF hall of fame.
Steve Carruthers, boat builder, former Valleyfield 2.5 stock record holder...All round nice fella.

We’ll there is a significant amount of work involved in building these steps rather than the usual you see I enjoy it so that’s what I like to do but others may not agree but it is in no way my idea to do this I got the design from my uncle who is in the cbf hall of fame for his boat building over the years and all his outboards he built along with all his inboards had these sponsons along with all the unlimited boats that currently run so all I can say is I’m going to continue to have fun building these crazy steps and hopefully see success

Who is your uncle?

Yes Fast Lap time wins IF you get a great start position and do not get stuck in the really bad water back in the pack. Been in both places and bad water is not good even with good lap time. If I had the position I would clip the lead buoy in the turn to force the guy behind to cross the wake if they were taking the inside. Of course without cutting off and violating the distance rule.

Don't get me wrong, I think your sponson design has excellent potential to work well. I just think you are anticipating an improvement in a range that is not there to get. There are and have been many different sponson designs and many different fin setups over the past 70 years and if one was that much better than any other everyone would be using only that one.

I don’t believe one should rely on sponson suction to slow one down to turn that’s what the throttle is for keep the sponsons hanging as long as possible and when they do come down why not have them skip rather than suck as for the ventilated sponsons and possible transom I love the idea but did I not read somewhere that it is not aloud?
