Re: Desperatly looking for an answer

I think Jim nailed it, Unload the boat and take her out again. I would use the gps speed as my baseline preferably at slack tide so that doesn't affect your numbers.

Re: Desperatly looking for an answer

Is full throttle the same RPM as last year? Maybe your filters or air intake are partially clogges. Same sails as last.

I believe that is what I will have to try next...I'm gonna empty the boat and go for a spin! Hopefully will resolve my problem.
Tides not an issue on lake Ontario...

I always use the same way of measuring speed as well so I dont get different input-ouput

Re: Desperatly looking for an answer

Is this only under sail, or power or both?

If both, almost certainly a weight issue. Either too much, or in the wrong place or both.

If only under sail then it's likely a rig tune problem, trimming problem, or your sails are a year more blown out, and finally hit a critical curve in their life span.

If only under power, then check your tach. It might be giving faulty readings. Or the engine isn't getting to full RPM. weight can exacerbate this problem, as the more heavily laden she is, the more torque you need, and less speed. If the prop starts to cavitate, then additional rpm is worthless.

Re: Desperatly looking for an answer

You have a 143 water capacity? with tanks full that's almost 1200 lbs. Did you always sail with your tanks filled ?

Still, you should easily get more than 6 knots at full throttle even with full tanks.

I can get 5.5 out of my 30 year old westerbeake 27 if needed, on a clean bottom without taking it all the way up.

Re: Desperatly looking for an answer

It's the anchor! Raise the anchor!!! Probably a little faster in DEEP water, right?

It is happening under sail AND motoring. Last time I was out, both my water tanks were almost empty. My fuel tank shows half.

The boat not having a generator and empty tanks, my guess is it's not a weight issue but maybe more a weight distribution! I will try it out and let you guys know!

Thanks you for your inputs...

Re: Desperatly looking for an answer

I think you are on the right track. Everything else being equal, it is weight. Either more of it or placement. I wouldn't start pulling stuff off of the boat unless it''s junk that you don't need. Redistribute, and go from there. However, this might be a good time to start looking at the stuff you accumulated in the last year and seeing if you really need it.
