"speed wobeling"

Chopppywaters · 04 August 2005, 23:22

heh didnt kno how to spell wobelling (still dont)[i mean when the boat tips from side to side]
SO with that out of the way kind of i was wondering if anyone has expeirenced this tipsy feeling with your boat at high speeds? I was on my friends RIBCRAFT 5.85 today and when we pushed it to WOT i thought the boat was going to become airborne (flat seas) or we would flip...anyway to fix this/why does this happen?

sorry i forgot it if anyone needs more info there were 2 of us on board, 115 hp Honda 4stroke, little to no gear, calm seas, and we were using the trim. O and the boat is 19 ft..i think thats all

Sounds to me that you need to trim in more but what do I know nothing

We have a Ribcraft 5.3 with 90hp we get the same problem at WOT if I am trimmed up too far

You are describing "chine walk". You need to trim the engine down slightly untill it stops.

I get that as well. Trimming down does stop it but slows you down a little.

heh so other than trimming theres no real way to fix that? Im not a big fan of trim tabs because i have baddd expiernces with them, and no clue how to use them efficently lol.

I think you will fined that it is not Trim Tabs, but trimming the outboard in that you need to do!

Well my 5.75 never did it with a 100 on the back!
But now I have a 150 on it if you trim it right out then it will get a bit wobbly!

And i would be interested as well to see if any 5.85 owners have had this problem too

it could be because the engine is mounted too high on the transom. if this is so, trim will not really help the case. i experimented this with a similar rig. you'll be surprised how much a cm does to the handling at high speeds!
