OP, finally after 3 pages some revealing info comes to light, (part of the boat is missing). Rumars has hit the key point. An old saying; "When...
I'm assuming the boat will have a fairly distinctive "scum line" that shows where it has been floating. With the boat at rest the CB and the CG...
With the boat hauled out and fairly level you should be able to ascertain the "real" waterline where the boat actually floats pretty well. Go...
Water tanks for ballast work well in submarines and freighters. Not so well in small volumes. Fresh water = ~62 lbs. per cu ft. Typical 3K psi...
5 to 6K ballast? That's a joke on something that size even if it would have been left as a sailboat. My own little 35' sailboat has a bit over 6K....
It started as a sailboat hull, doesn't it have ANY BALLAST? Gizmos like fins, bilge keels etc., can reduce rolling underway or at anchor, but they...
Various sizes of metal discs that come from punching holes in sheets of metal. The scrap from punch presses. The term prefix "boiler" comes from...
Ah-ha, now we can "see" what you're up against. Just a thought, (and depending how things work out,) that I-beam provides a good "mounting" for...

Their isn't any single "Definitive" answer. It's similar to; "It depends upon what your definition of "Is" is". You're putting "grounding" and...
The last time I read post #1 their was no mention of inverters. As I wrote, the GFCI breaker ON THE DOCK is your first line of defense, when it...
The ABYC standard of connecting the 12V neg buss to the AC ground buss, (green wires,) dates back to the time when boats had quite rudimentary DC...
4mm thickness? no matter how much rigidity you can obtain from shape/form, the ability to withstand point loading is quite limited. Looking at...
You want to go fast with a short stubby boat? Sounds like an AU class Utility Racer. Atkin & Co. - Lipperty Lip You want something that's actually...
"Servo Yachts", a California company, the land of fruits and nuts. :rolleyes: No more need be said. I'd first thought it might be from some French...
Ah yes, the Mitty Ann, an excellent example of a genre of boats that Atkin excelled in. The wholesome inboard utility of displacement speed/hull...
Always easier to cut down rather than add-on that's for sure, but you built a good-looking hull. Pushed too fast the stern will squat which will...
The sheer isn't a big deal, should you wish, it wouldn't be a big job at this stage to simply spring a batten and cut down the sheer up forward a...
"Some" inefficiencies. :D Me thinks that "some" is being quite kind, but yeah, they did the best they could with what they had. ;)
