Marmot has taken this thread way off base from the thead and my post was in line with lengthened yachts and what you experience with lengthened...
Call Sevenstar or DYT. There normal route is that area....Ensanada MX to Ft. Lauderdale. I don't know of any freighter that ships to the Mid...
When you add a cockpit stern extension to an existing hull, the center of gravity does move aft. But since the cockpit is lighter per linear foot...
Of course, but since you added length also, the COG would be further foward from the transom (measured in distance or percentage to the new...
If you added a 10' extension to the stern, left the fat guy in the same place, the boat would then be level and even slightly bow heavy
Compass is most likely. I ran a 54' Hatteras and sometimes it would track perfectly, and sometimes it would just make a weird turn at...
Rudder feedback is easy to tell from the helm. Turn the autopilot on in standby where you can see the rudder indicator on the autopilot unit and...
The CG may very well be further aft of the bow of the ORIGIONAL HULL. BUT, you now have a new hull that is longer, so now the CG in percentage of...
I forgot to mention it was 1550hp C30's. I also ran a 52' Cabo SF with C18's, one of I think only 3 FB boats they built in the 52'. It was a...
Well, yes I did get here today. Yesterday it was calling for 2' or less and 5 knots wind SE. Well it was beautiful all of the way from Boca...
Why not run 80%? A 54' Without a tower and C18's absolutely...... A towered 54' with 1550hp C32's runs 32 knots at 80%, Without tower 34 knots....
You're wrong. You are adding length to the stern and less weight to the stern extension per linear foot than what is forward, so the center of...
A 4" grinder with a cutoff wheel, probably but very messy. Is it not possible to take the top off and seal them from the inside so they're...
No, a lot of detroits had (ac) Delco gauges, some manufacturers used SW, but I know Bertram, Viking, and Searay back in the D.D. days used VDO.
Call "Lauderdale Speedometer" in Fort Lauderdale,FL. They have a million gauges for marine in stock, that's about all the specialize in and they...
No, 2003ish-2008 was exactly when all of the problem boats were made. One guy had 2 Bertrams in a row have serious structural issues and...
I have done on average 12,000-15,000NMs at sea per year since 2002, and I don't know how many miles before that but still quite a bit. I saw a...
I would skip the Bertram entirely in that build era for fear of it coming apart and disintigrating. They had many yachts that had major...
Just a cockpit adds a lot of bouyancy without adding a lot of weight compared to the rest of the boat which has a structure above it, per linear...
Because they're powered by the engine bank. So if you lose everything but the engines you still have gauges for the engines.....just measure the...
