Hi, I am really happy so far with my Vega. I knew the handling astern would be a bugger and was prepared for that before buying. My dad's friend insists that I check the propellor is the right size for the engine (a Volvo Penta 2001). I could see how the wrong propellor for the engine could affect the handling, but I suspect this has nothing to do with the handling issues astern inherent in an Albin Vega but thought no harm in checking with the fountain of knowledge that is the AV group. I have uploaded the picture of the 3 blade propellor as an album called Vacherin. Unfortunately I do not have dimensions as its in the water currently.
Propellor for Volvo Penta 2001

Knowing if your prop is correct in pitch and diameter starts with some info for the engine.
The mfr will specify a max horsepower at some RPM.
You go out on your boat, hopefully on a flat day with no tidal currents to bother you, but that's
not necessary as far as I know. Then you full throttle the engine. The RPMs should go up to the
manufactruers specs for the engine and no more. Note your velocity and that's your max speed.
I think if you are over propped you will get a lower RPM,, under propped you get a higher RPM.
You will mess up the engine if you exist like this for any length of time.

I would say that if the engene comes up to the recomended speed for
d cruising the wheel is right and in reverse you get what you get.
With the prop above the wheel you are not going to get much steering
control in reverse. I don't know what the operating speed on your
engine is but that is what you need to get. Everything else is just
what you get. I compensate by picing the marinas I keep the boat in
slips that let me back out with the boat clawing to port as I back .
Once you learn to compensate you won't care one bit how it backs.
I grew up saing on my fathers boat that fo many years had no engine
at all and then had one with no reverse. I don't make a bit of
difference. Doug

I have been thinking about adding a rudder extension only at the prop wash at the top of the rudder. It would be pretty simple to build and would help with controlling the boat when backing up. I know that any added rudder surface adds drag/cuts speed. But that was making the entire rudder wider, not a trim tap if you will. Still thinking it thru.

The reason the Albin Vega has a mind of her own when backing is really simple. It really has nothing to do with the prop or the pitch. Which is important to be matched with your engine and the boat. But backing a vega will always be something only your boat knows. The reason is that the propellor is aft of the rudder. The Vega is one of the few boats that I know of that the Prop when backing does not have any real effect on the rudder. I have tried everything as my Vega always backs to starboard. It is common for single screw boats to always back to port. But not the Vega. LOL. If you are single handed in a tight area I have found that running a line from the stern cleat to the dock that you can control from the boat will help get the stern around and you pointed in the right direction. Good luck.
When I have the b*lls (and the space) to reverse with full throttle and tiller hard over I find that the bot will yaw in the direction that I want.
It takes a while though...

Hi Larry
Have a look at the Vega Help Rudder. Made and

and never installed, perhaps we could come to a deal?

Give her a good burst of power in reverse to get her moving, then kick into neutral to eliminate prop walk, and she should turn with the rudder. And ... if you can .... give her a little shove in the desired direction before you hop aboard. Works for me ... mostly!Peter.
Before I sold my Vega I had a small MInn Kota electric fishing motor hung off the stern -- works very well actually. I had a motor in my shop and a Fulton scissor mount already, so I figured why not? I also had the scissor mount removable so that the entire thing slipped into a small, mostly flat aluminum mounting plate (thus it was pretty much invisible when not mounted). I could use this little electric motor to kick the stern around easily. And I once had to move my Vega through the marina to a different slip when my diesel was being worked on. The 55Amp Minn Kota easily moved the boat at about 2 kts to a different slip, no problem. I got the idea because I had bow thrusters on my Hallberg Rassy 40 (once in Mexico I had to take the HR onto a marine railway, located on a river outlet with a current that ran several knots, and on the day I did this there was a 25kt northerly cross-wind blowing). This is sure a lot easier then using a small gas outboard mounted on my dinghy to be used as a 'tug'. By the way, the electric would push my dinghy at a good clip for hours and I didn't have to carry yet another fuel on board (gasoline). I just charged the battery with my regular battery bank.

Hi Chris,
Did you mean 55 lb rather than 55 amp?
Anyway, the 55 lb is a good choice for electric motor rather than the
bottom of the line 30 lb. like I chose.
Once I got down south where the tidal currents are very large, up to 4 kts.
my electric motor couldn't keep up and I would just sit one spot while trying to
get my dingy back to my vega.
I meant to try the 55lb electric but never got a chance. But I know the 30 is not
adequate.

Great idea, I've considered it also and already have a 12 volt outlet on the stern coaming. It would be a quick and relatively cheap fix. Whenever I need the stern to go to starboard when backing I just think port, port, port. Lyric being the obstinate lady that she is then goes to starboard. Other times she goes to port if I think starboard, starboard, starboard. I have used the engine to "walk" the stern by revving it repeatedly but this only works when you are not being pushed by the tide or wind in tight quarters.

Another Idea I have been told is to put a small engine mount on the stern and a electric trolling motor like those used for fishing. Then when backing you can use the electric trolling motor as a stern thruster. It really is not a bad idea. You could also use the motor for the dingy. It's just an idea I have been thinking about.Viking #3361 Manning J. Harvey IIIUSCG Master 200 GT, Near Coastal.Senior Chief Quartermaster, Submarines. United States Navy, Retired.manningharvey@...

Chris, I just bought a Minn Kota Rip Tide for the dinghy. What kind of battery were you using? I'm running on an old wheel chair gel cell, but will need something better soon.Peter.
My favorite is the Optimus Blue. It is a deep cycle, AGM, and seems to take a charge better than the old square batteries. Plus they have a great handle on them. I prefer AGMs over gels as they seem more robust and they can be charged the same as a flooded battery. Plus the Optimus looks much cooler (and that is really important). Most wheel chair batteries are relatively small, Group 33 or 34 I think and they are pretty small. I used the group 24 as that is what I had in the boat. By the way, by extending the below cabin sole battery shelf a little, it is very easy to put three batteries down there (and contrary to some other emails, it doesn't hurt a battery one bit to be under the cabin sole). I actually looked around a bit and found some Optimus cosmetic blems at a local dealer and the cost was about half a "pretty" one. Chris BrownThere is

The Rip Tide is a good choice as it is rated for Saltwater (my MinnKota wasn't, so I rinsed it off all the time) I was also asked about the little aluminum slide mount plate I mentioned. I used a Fulton scissor mount and Fulton makes (at least made) a pretty flat plate that these brackets just slip in and out of. I just checked Amazon and a company named Trac makes one ( check this listing out on Amazon: Trac T10053 Adapter Plate for Aluminum Motor Brackets). Should work on a Garlick mount I would think. I was always going to paint the aluminum plate white to match the hull, but the little aluminum plate isn't that noticeable. It would work well with small gas engines also (thus allowing emergency propulsion). I once had a 35 footer in a charter fleet and the engine was flooded with Seawater by a charterer while up on San Juan Island. I friend with a Cessna flew some of the guys up, then used a 2hp Honda on a rubber dinghy lashed to the stern to move the boat to Seattle -- no small trip without good power or wind. A little 4hp on a boat mount would have made the trip much easier (and a lot faster).Chris BrownThere is
