making the boat more steady in a straight line?

[crus]

i live in amsterdam near a canal where i put my 2300scr.
i noticed that it is very hard to go in a straight line on narrow canals.

the boat never goes in a straight line but when putting the wheel in one position.
the bow sways from left to right and back quite heavily so you need to correct the course constantly.

are there any mods that give you more control. (i'm willing to sacrifice some topspeed for this).

someone said perhaps a different screw.

i was thinking maybe attaching some vins on the bottom or back?

Slow speed wonder is normal with single I/Os. Try trimming the drive up some to see it that helps.

This is with all boats, but slightly more pronounced with I/O's and outboards. The bow will always attempt to wander. The degree to which it wanders is a product of oversteering.

If you adjust after the bow has wandered, you've reacted way too late. The second it starts to go to port, turn to stbd. The second the bow starts going back to center, center the wheel back again. If you wait to straighten the wheel once the bow is straight, you've again, reacted way too late. The other key is not turning the wheel too much. That is what causes the behavior you're experiencing.

as a test, in a fairly wide canal i set and held the wheel exactly in the middle for a couple of minutes, so without any correcting.
what happens is the boat goes in the same direction but the bow sways from left to right... like a perfect sinus wave... so i'm failry sure it has nothing to do with correcting the course.

nevermind, i think i found something:
course-keeper and ruddersafe.

The course keeper is what you need! So much easier to manoeuver at low speed or keep on course.

i just read somehwere that the coursekeeper deteriorates very quickly.
also the ruddersafe also moves out of the way depending on the speed so it doesnt create drag when speeding.

what is your experience?

It is only our second season with the course keeper and so far it is still looking good. It is painted with anti-fouling. One corner is a little bent tho where we must have hit something.

Our Maxum has got a diesel engine so no speeding for us.

I think you would be pleasantly surprised with your low speed handling if you trim the drive up as Mike suggested, and, add a four-bladed prop.
I also noticed excellent slow speed stability with smart tabs set all the way down. The prop and the smart tabs will also improve performance when you get out on the open water.
I have no experience with course keeper or rudder safe. Do they hurt performance or get in the way when you get out on the open water?
