Listing ??

[starcrafttom]

I have a problem with the trim if the wife and son are on board and the water tank is full. Even with the trim tabs I have a hard time getting the boat to trim flat. It tilts to the port side. I may have to buy a kicker just to even out the boat. I have been only filling the water tank about half way and running the gas out of the port tank first. this seems to help.

Wow. I had no Idea that the water tank held so much. That will definitely solve the problem. It's nice to have access to all the knowledgable people.

[starcrafttom]

20 gallon x 6lbs a gallon ( I think) 120 lbs. That should help a little.

Tom,

I think you are a little light. Water is 8lbs/gallon and gas is 6lbs/gallon.

I said (I think). cut me a brake guys.

Sorry Tom,

No harm meant. Just thought I would point out that it was heavier than you thought. I only remember as my dad was a Civil Engineer for the Corps and he used to drill that kind of stuff into my head as he was building fish tanks and stuff just for the heck of it.

You gize are funny as hell . Well, I have writen about this topic a LOT and thankfully I was able to find a little back-up on what I did write, from a newer style C-Dory to boot (take that Larry )

Here goes: (I hope this works ) ...

Man, Red Fox is absolutely right. When I went from a single 2-stroke to twin 4-strokes, the handling difference was pronounced. The boat was a handful in following seas with only the light one engine, but with two heavier engines, the boat tracks like on rails, with no more yaw tendency. With any boat, you want to keep the bow light in a following sea, but a dory, which tends to float bow down at rest, needs to keep her bow up in a following sea, or she'll tend to dig her bow, and if the seas are quartering, will be pushed aside from the stern, causing a nasty yaw. The twins, with their heavier weight and greater directional drive, have completly solved the problem for Sealife.

I guess I shoulda qualified what i wrote many times by stating the need for trim tabs when your rigged heavy on the stern
Most say nay to the heavy-stern idea, cuz the bow needs to ride low and tight in the water (when heading into chop) bow weight helps tons in this regard but in a following sea (in almost any boat design) your F'd!!

As far as trimming to offset listing: It helps! but often there is not much you can do, when you need to slow down. The faster you go, the more trim you get remember Their speed-related...

Greg,

Maybe I don't have any problem with following seas because my boat is usually heavy. When we are on the water we are long range cruising/liveaboards and we have a lot of stuff and supplies.

When we get together someday, take me for a ride in RedFox, maybe I'll like the hot rod stern heavy flattie.

Guys, bottom line is this... listing due to body weight is a matter of physics. There is a direct porportional relationship between the mass of the vessel and the mass of any object placed within the vessel. The closer the two are in a mass versus mass relationship, the more the interfearance between the two absolutes will be.
Unfortunately guys, the way to minimize listing on any vessel is either decrease the mass of the Captain (if he's running solo) or get a vessel that exhibits more mass (i.e. bigger boat).

Unfortunately, for those of us with limited cash to increase the mass of our boats (size) the only option for us is to add ballast to the port side... or... lose weighat. The later is a bummer, counter productive to the American way of life, and to the known physical law of nature... "Bigger is better"! I say pay the arabs for gas and add 50# ballast to the port side.

This is the American way.... Hooo Rah!

Did Mr. Fox say he was having girl friend problems in a recent post??!? Hmmm.
