Are you "T" tipping?

#1

How much does a “T” top play into lateral stability on alloy boats? Is being lighter a problem? How much is the wind a factor?

Because the hull of an alloy boat is lighter than a similar size FG rig, a T Top can adversely affect an alloy boat in some conditions. Both boats will have the same size T Top, but the greater weight of the FG boat will provide more stability in a crosswind.

This is an earlier CC that I owned. Running in a beam sea with wind over the beam could be tricky at higher speeds. As the boat rolls to leeward with the wave motion, a greater area of "sail" is exposed to the wind, which increases the lean & exposes more area.......................you get the idea. Only ever encountered this problem once. Throttled back & all was good. Never ran really quickly in these conditions again. In a head or following sea there was never a problem.

I put a custom "pilot house" (T-Top with canvas side curtains) on my 21' Bayrunner Baja. I can feel the side torque in a beam sea and wind, but I've never felt like it was going to capsize. I only have a 90 hp. outboard and in rough conditions I only do about 12 knots, so that probably is the right thing to do. I am interested in any comments the rest of you might have. Tin Man

I don't feel my Pacific 23 " Tip " but with the high sides and T-top it can be fun when loading back on the trailer on windy days. That was fixed with the guide on rails.

I always try to get on the down wind side of a dock also.

My boat has a 18* dead rise with a 60* deep entry and perty good chines so the roll isn't much of a problem .

I should clarify that I was initially running at around 25 knots & slowed down to 20 knots. Would I have tipped? I doubt it but a decent gust could have made life interesting had I maintained 25 knots. Welders boat would be a lot heavier & bigger than my CC. It was around 19' with a 90 fourstroke & as the pic shows, it was a large TT.

Are you saying the Pacific has a 60 degree entry? Just curious I thought it was much less than that.

As a person who has had T-tops on my glass boats before, then even took off the t-top on my old boat and sold it, then had a higher windshield built with a nice rail around it. So when it came to having my Pacific built, I knew NO t-top would be included in my build sheet.

But, the reason I say no is because I fish, and don't want it in the way. And I fish always on anchor, and thats where a T-top has not done me any favors.

The current lays us one way, then the t-top grabs the wind and lays us another. MY fishing style, unlike anyone elses on this whole forum means that I have to "lay with the current", it's what I have to do. So no tops for me, except a BLM designed Super Top.....I love that boat!!

Tippy...I believe Welder has answered that question.

You will usually pay more for "dry stack storage" though with a T-top
