Same weight hull, tin vs glass...wind?

As Im shopping around looking at boats one of the criteria for me on the next one is that it doesn't get blown around as much in the wind. Currently my Lund gets blown around way too much for me, i also do a lot of dropshotting and deep water fishing for smallmouths and its really tough on the typically exposed lake I fish. I think a glass boat would help to alleviate this problem, but then again most of the glass boats weigh considerably more than similar sized tin boats...so I'm not sure if the better reputation of glass in the wind is as much a factor of typically weighing more as it is due to the hull material/shape? One of the glass boats I'm looking at is quite light for its size, its very similar in weight--even a bit lighter than some comparably sized tin boats--so I'm wondering if you were to compare similar hull types (tin deep v compared to glass deep v), same length/width, SAME HULL WEIGHT, what is the real-world difference going to be between tin and glass as far as wind drift is concerned?

The bottom design and draft coupled with freeboard will determine how the boat drifts. Generally speaking, true V hulls with no sponsons, reverse chines, etc with lots of freeboard will drift faster. Weight doesn't really have as much to do with it as the above.

Steve is right, it isnt the fact that a boat is fiberglass that makes it less susceptible to wind, its the design of the hull and the sides of the boat where the wind can catch it.
What model lund do you have? I would imagine that a ProV would be about the best overall hull design that Lund makes so if its not a ProV perhaps check into them.
If the back of your boat is just a "V" there isnt a reverse chine which Steve is referring to. That will make a huge difference.

Yup, freeboard and even weather you have a single windshield, full windshield or no windshield. If it was just weight, you could just fill up your livewells.

I have a 2002 mr pike 17, single console. As near as I can tell it functions as a sail on a windy day. At one point Sunday I looked down at my GPS...I had trolling motor off, and the wind was blowing me a sustained 2.5mph sideways. Hard to maintain a tight line or fish slow in those conditions.

I think what Im hearing is that the ultimate weight of the hull does NOT have as much to do with how it drifts as the shape of the hull does? So, a lighter boat that sits lower in the water due to the shape might actually drift less than a heavier boat that catches the wind more? Is it a given that a glass v-hull that's "the same size", and the hulls weigh very close to the same, will sit lower and therefore drift less in the wind than my boat? Seems like the typically convex curves of a tin boat versus the concave curves of a glass boat would result in Tin having a larger hull volume than most glass, and therefore they just float higher in most cases no matter the weight?

Just as one example, a 20' lund predator, which has a lower profile and layout that I like is quite a bit heavier than a tuffy x-190...I would think the glass boat would sit lower and therefore drift less, but since its several hundred pounds lighter I wasnt sure. Some of the older ranger multispecies boats are also fairly light for their size, hence the question.

Buy a drift sock... or 2. Much cheaper than a new boat!!

true perhaps but this isnt the only reason for a new boat, I have a couple frustrations with it that arent the fault of the boat, its just not exactly the right boat for me. In any case, 1) a drift sock doesnt work in very thick weeds (there's LM bass to be caught too, and I like frog fishing and flipping the inside weed edge too much rely on a drift sock), and 2) I havent really tried it, but even one drift sock sure SEEMS like it would be a horrendous PITA. Is a drift sock or two really as-effective for getting my little tin boat to stop drifting in the wind as much as getting a different boat would be?
