Hey guys,

I'll be blunt, I'm a total noob when it comes to boating. When I was a kid I piloted my fathers Bayliner Arriva (Force outboard), and then once I was 13 he let me drive his flat bottom (426 Wedge :joyous: ) and his 72 Kona (454 and Berkeley), but that was only 2 seasons on the water, and my part was strictly little put or a few speed runs (on non-crowded days, calm waters). The boats were sold and I didn't go to the lake for years, aside from a half day on a rental pontoon.

Fast forward a few years, I went on a few Colorado River/Havasu trips (passenger/tow rig driver only) and then last year, I spent 5 days on the Colorado/Havasu in a 18 ft Maxum 1800sr. I was the sole driver aside from a friend who wanted to go from our cove on Mohave to the Marina for adult beverages and snacks. This particular boat had a horrible time in the chop on Lake Mohave. Our top speed was about 20. That was going into the wind, so the chop hit us hard and dead on. While this was going on my friends in their mini day cruisers and tunnel hulls were to our left and right skipping over the tops of the chop, but everyone in our boat was getting beat on good. This was also my first time in chop in an I/O, so I had fun playing with the trim trying to find a sweet spot that kept us from nose diving into the waves. I eventually was able to find what I would call a sweet spot and was able to keep my speed up, but all our friends were long gone, except for a wakesetter that seemed to be having just as much of a hard time as us, he stayed behind us, didn't even try to take the outside. This boat also did not like crossing wakes from my friends boats as they blasted by us. I was always taught to take it at a 45% angle and stay on the throttle through the cut, and this proved to work well in the Kona and the flat bottom, but this 19 ft Mercruiser V6 just did not like it. This boat was not mine, but a loaner, so I took care to avoid hard hits to this boat, but I was just having a hell of a time avoiding it. The Colorado river (Needles down to Pirate and Beyond to Havasu) was especially rough, as there were a lot of larger boats blowing past us when we were cruising at a decent speed, including one Magic that did a sharp hard U-turn swinging from our right to right in front of us and then back around to our left, and that wake threw us around like a bath toy.

So all of this being said, I am looking for open advice in regards to this and how to avoid these situations in the future. I wont be driving that boat again, but I was recently offered a trade of a 21 ft Sleekcraft, my dad is encouraging it, as hes been itching to get our whole family back on the water. The boat has a 350 and a Mercruiser outdrive (not sure which one), and I think it would be just what I need for a summer on the water, and I have quite a few events on the river/Havasu from April-September. Will a 21 ft semi V will handle the rough stuff much better than an 18 ft deep V?

Also would love to hear your opinions from seasoned boaters to a novice.

Thanks guys!

I doubt it. With most v hulls, the faster you go the better the ride. Next time go faster, like your buddies were. :D

And get a boat with enough power to go faster, like your buddies.

I would think it would handle it better. How much does the Sleekcraft weight? The weight helps for this kind of stuff. On our old light boat we got beat up. Now on the Crownline I just trim in to get the nose down a little and take it on when needed.

Having gone from an 18' deep V to a 21' shallower V, but still 16? deadrise, I can assure you that it is possible to have a dramatic improvement in rough water capability.
The design of the hull and build quality are very important, however. Experience and trim tabs improve your running ability in rough water.

Amen. What you learned is that the design you have is not made for rough water and indeed is not seaworthy for that use. They have that low scoop bow, no flare on the bow, no splash rails and chines to deflect water down or out--the bullet hull design is simply a failure, but clearly it sells boats.

The only way to improve things is exactly what you did--play with the trim and speed to find what works best, but some boat are wet and rough no matter what you do. Moving people around helps. On a side wind, raising the windward side can help. Practice practice practice.

BTW going faster is usually not the cure

Couple of comments. Agree that the hull has to match the conditions for the best performance. Also agree that sometimes faster IS better. Also agree on 45* when that is the right answer. Walking the troughs when that too is the right answer.

I had a Ranger bass boat with a pad hull, dead rise at the stern, great bow lift at speed and plenty of ponies. I found that I did better in rough water up on top.....rough water within reason for the size of the boat. Other thing I found was that trimming the bow down somewhat, in the "on top" configuration made for more wetted surface and at the higher speed better wave to wave contact working the V in the bow area to my advantage. I would adjust speed and trim so that the transom would skip from wave top to wave top; skip being defined as a slight drop of the transom just past the wave crest but smooth and easy on the loins.

Another thing I learned to do with this boat in big water was to get the boat right at planing speed where the bow was ready to drop but would control it best I could to keep it airborne, I mean 6' in the air, headed dead ahead into the big waves. This gave me about 6' of cushion aka shock absorber from wave to wave and really made for a dry, soft, ride and not bad at all, but not fast....course the idea was to get through the experience, not see how fast I could go.

Many years ago I had a small semi-v runabout with foredeck and windshield and a really nice bow flare. Not a lot of power so I had to stay "in the water" but in adjusting the speed and taking on the waves head on I was able to have a soft, dry ride and work the flare to the max. Took awhile to get where I was going but it worked and I made the trip many times.

In short, get to know your boat, what it likes and all and what it can and can't do. As you said, play with it till you find the sweet spot.

HTH,
Mark
