I have recently obtained a 78 version #729, tall rig, fin keel with the motor mount on the port side. I have not sailed it yet and won't be able to until spring thaw. Information on this site indicates that the mounting point as on the C22 is wrong, mount should be on starboard. Is it realy worth switching mount, controls and linkages, or is this so subtle as to be dependent upon hemisphere?

Hi Derek

The earlier versions of the C25 had the motor mount on the port side. When the seperate fuel locker was introduced it was too difficult to put the mount to port - so the factory began placing the motor mount on the starboard side from then on.

Bill - "This Side Up" #2262 must be one of the transitional models. It has a separate fuel locker and the O/B on the port side.

Maybe that's what makes her so fast!

Derek,

That information on this site is wrong...you do not need to switch the mount.

Some Catalina 25's have a weight bias that makes them list to port as much as 5 degrees, sitting still at a mooring. This weight bias will produce a noticeable difference in sailing performance between Port and Starboard tacks. My '79 (hull no. 1205) was like this; the boat had the motor mount on port, causing a 5º list, and sailed much stiffer on a Port tack beat than on Starboard tack. After I swapped the motor mount and swim ladder to opposite sides of the transom, the boat still listed about 2º to port, but the sailing performance was more even between port and starboard. Moving the motor mount is a LOT of work, and of course you have to fill and re-drill all the mount holes, but if you have a large, heavy 4-stroke outboard and the boat is listing noticeably to port, swapping the motor mount to starboard will help.

Have you chosen a name for your boat yet? Which interior does the boat have, Dinette or Traditional?

my 78 fin standard rig has, of course, the motor mount on port. No noticable list although I keep the starboard water tank full for ballast on that side.

No need to worry about moving the mount. If your boat has a list with full fuel tank just distribute weight inside the boat.

You will always need to balance any vessel.

200 lbs of lead shot in 25 lb bags on the starboard side balance the port side weight of the galley, head, holding tank, fuel, and motor on Nin Bimash II. Docking at my home on Neebish Island is port side in, and it is nice to have motor to port so I can dock and remain at the controls. there is a 1 to 2 kt current so usually I can leave the motor in fwd at low idle just holding the boat against the dock long enough to set primary lines before shutting down.

While sailing performance is important, and a list can effect long distance navigation, another concern, more mundane, is that when the boat is out of trim while moored or docked it will not shed water as designed. Pooling can lead to seepage into the cabin and possible delamination not to mention deck discoloraton.

ORION #2343 1981 has Port OB mount and Port gas locker. Oddly enough she trims level despite this, possibly because both batteries are at aft end of Starboard seat locker behind (empty) water tank. Also, motor is a 2001 9.8 2-stroke Nissan, therefore not so heavy as many others. She does trim slightly nose down when empty, but not so much that the cockpit fails to drain. I do not have a fixed swim ladder (wish I did) but do have one of the old heavy folding plastic jobs, sort of a cutting board or starboard material, this is pretty heavy, and stows lashed up in the quarterberth outboard, so maybe that adds to the level trim.

My 88 tall rig is what Larry would call a Mark IV. It has the port side fuel locker but came with the motor mount on the port side. I hated that list. Other boats would circle around our mooring thinking we were filling with water. When I had the hull painted a few of years ago I had the yard switch the mount and ladder. As Larry mentioned, their is a very slight list which disappears if the water tank (under the starboard setee) is full. Batteries (two)are on the centerline under the companionway ladder so they have no impact on the port-starboard attitude of the boat.

Thanks for all of the responses. I can't comment on boat's ballance in the water since I haven't floated her yet. It is true that head, head tank, galley, motor and tank are all on port side only ofset by water tank on starboard. The 200 lbs of lead as an equalizer doesn't sound too interesting although 20 gallons of scotch may be more palatable.

"Have you chosen a name for your boat yet? Which interior does the boat have, Dinette or Traditional?"

Boat was named Passages, a name that we will retain in respect to previous owners and is a Dinette model.

Derek, 200 lbs of lead take up very little space and you will still have plenty of room for that Glenlivet. In every port around the North Channel the LCBO is the place I head to keep my scotch supply at an acceptable level.

My 78 has a Honda 8HP mounted on the port side without any noticeable list. About the only thing on the starboard side is the freshwater tank which I do not use. Having the motor mount on the port side makes for easy access to the mounting bolts through the lazarette if it ever needs removal. Also my fuel storage is in the port lazarette. If the engine were on the starboard it would be a longer reach for the fuel line.

Speaking of lists, we all know that when one person goes forward to the bow, the stern lifts (if anyone has a short shaft OB, you know what I mean) and when no one is aboard, the boat is sitting on her lines.

Question: What happens to the boat's stance when we put 600lbs of captain and crew in the cockpit?

well the bow doesn't dispalce as much water as the stern so when the crew rushes forward to fend off, taking the shaft out of the water....uh......well.....no reverse.

600 lbs in the cockpit does a lot less to the trim.
