Re: [PSUBS-MAILIST] Recent Eurosub Dive Experience




The Eurosub is a really nice sub and well deserving of notice and accolades it has received. I see it as an alternative rather than a replacement for the Kittredge subs however, since calling it a "replacement" has a connotation that the K-subs are somehow obsolete which I don't think is the case. While the K-sub plans could use some modifications to bring them up to date (about 40 years old now) and into compliance with the latest ABS requirements, the base hull construction and ballast control systems have proven to be well engineered and reliable. What's interesting to me about having Eurosub plans available is that it would offer a design with different enough subsystems (such as ballast and controls) to make it an interesting alternative. I don't know enough about the Eurosub to understand exactly how different it is from the K-sub design, however I suspect someone could take the K-sub plans and modify them into a Eurosub, and modify the Eurosub plans into a K-sub. My point being that I think its difficult to substantially differentiate one well designed general purpose submarine over another, especially for recreational use. For example, is a sub designed for 1,000 feet using hemisphere heads functionally any better, or safer, than a sub designed for 1,000 feet using semi-elliptical heads? Once you've achieved a safe hull, many of the other systems are merely preference and do not substantially offer more or less benefit over another design; batteries inside or outside, fixed or movable motors, ballast fore and aft, amidships, or both.

I do hope the Eurosub plans become available sometime. I also hope PSUBS can complete our Open Source Submarine (OSS) project which I think will offer another option to home-builders.

All,
I recently had an opportunity to dive in Eurosub at Kreidesee (1 hr. and a max. depth of 50 meters) and to visit with Carsten and view both Sgt. Pepper & Euronaut. I was very impressed and appreciated the hospitality I received.

Let's hope the Eurosub drawings become available some day as I believe (my humble opinion) this design is a logical replacement to the Kittredge.

I really liked the hard ballast tank design as it also acts as an internal stiffener. The soft ballast tanks were also well designed and nicely integrated to the hull.

While I am far from construction of my own project I have now had the experience of diving in 4 different subs and I can attest to the value of doing so.
