Last weekend we did some surfing in the fog between Nahant and
Swampscott (massachusetts).

We were having a great time, until one guy needed to get a ride home.

http://www.nesurfski.net/

My version of the story differs slightly...

Both boats on the cover page on nesurfski.net belong to friends.

Last friday my friend, Bill K., put his Fenn Mako XT up for sale.  He
got 2 calls about it saturday, one while we were out surfing (for the
above incident). Sunday morning someone drove out from New Paltz NY to
look at his boat (a 4 to 5 hour drive each way) and bought the XT.  3
hours later Bill called me on his way back from the kayak shop.  The
Think Evo was on the roof of his car.  He had only been boatless for 3
hours.  Bill had been agonizing over whether to get a Huki S1R, the Epic
V10 sport, or the Think Evo for about 3 months.  

Today we paddled out of Essex Mass. to the break between Crane's beach
and Wingaersheek beach and took my Huki S1X and his Think Evo out to
play in the residual waves from tropical storm Noel.  I got a couple of
wonderful rides, a 100+ yards on each ride, moving well enough to do
nothing but brace and ride the wave, no paddling required.  

some days the surfing is good, other days it gets expensive....

I'm a little confused... how can you be boatless from selling just one
kayak?

Oh.... wait....

How does one tell if their kayak is trim, is the something I should be aware of? I ask because I took my Sealion apart and put it back together with new hardware and rigging and I set is so the seat is all the way aft. I am 200# an 6'4".
   
  Thanks for your thoughts

It seems to me that the important thing about trim is boat behavior
and handling. In some of the Mariner boats, Matt and Cam installed a
sliding seat, so that the trim could be adjusted with the
placement/weight of the paddler (in addition to careful packing).

For boats without a sliding seat like that, careful weight
distribution in packing is the way to go. You really have to get to
know how your boat is balanced "as is", and how it behaves, then
adjust accordingly.

Most of my paddles are local day trips, so my boats are usually very
lightly packed to begin with; just the stuff I might need for the day.
Since my boats can have a tendency to weathercock in certain
conditions, I might put a bit of ballast just behind the aft bulkhead,
shifting the CB slightly aft. Some People will place ballast even
further aft...it all depends on the boat, the conditions, and what
you're happy with in terms of boat handling.

To me the way to solve the problem of trimming or fine tuning the boat with
load is straightforward in kayaks with skeg. You just place your load almost
evenly with a tendency of more weight forward, and the kayak will
weathercock. Lowering the skeg can compensate for that, and you can adjust
the skeg deployment to reach a neutral condition for the wind and waves
present.

If unloaded, skeg kayaks are designed to weathercock and small adjustment of
the skeg will give the right trimming. 

I think the skeg is a good contribution to kayaking.

Rafael.

Paddlewisers,
   
  For me trim is all about how the kayak handles. In my kayak, about 2/3 of the weight has to go in the rear hatch, and being off trim even by about 10 pounds can have an effect, such as increased lee or weathercocking and broaching. As Rafael said, if you're a bit bow heavy, a skeg can be lowered to compensate. Since I haven't installed skegs in my kayaks, I carry a dedicated water/trim bag on trips when I do long crossings, and when necessary, I fill it up with ocean water and put it on the front or back deck to adjust the trim for better boat handling. The kayak is really stable with camping gear in it, so the higher center of gravity with the bag on top of the deck isn't a problem and actually makes the kayak easier to edge.

Hi Mike,

In case you (or perhaps some lurkers) are not familiar with the effect of CG
placement on your paddling experience, here's what happened to me last year.
We were on a three-day camping excursion down the Peace River here in
Florida, and we carried our water as well as the normal camping gear. My 14
ft Wilderness Systems Cape Horn was loaded to the gills and then some. But
since it was a flatwater trip I didn't mind.

Day 1 was great, my packing strategy worked. No issues.

Day 2, I drank a couple gallons of water by then, and packed everything
where it was the day before. The empty water containers were ahead of my
foot pegs in the cockpit where they had been before, but full of water. This
day I couldn't get the boat to go straight. Anytime I put any speen on, I
mean like three mpg or so, the bow would fall off to one side or the other.
Quite frustrating. I was glad when we stopped for the day.

Day 3, suspecting that I was loaded too heavy aft, and having consumed more
water, I put what water I had left forward, determined to prevent the
problem I had the day before. And that I did. I couldn't get the boat to
turn without a LOT of effort on my part. It was obvious I had too much
weight forward this time.

I still couldn't tell you by looking when I have the boat loaded properly.
But I can tell you by paddling it when I've got it wrong!

Hope this helps.

Carey

Easy fix, just refill the containers with river water to maintain your 
perfect trim. Or add Genuine Florida Ballast Rocks, which tend to be a 
little lighter than the Canadian variety.

I suppose that would work, but I prefer a lighter boat, so I just need to
adjust things a bit here and there. The trick is knowing that it needs
doing.

Mike,
I prefere the handling of my kayak with more weight astern. So, I cut my 
seat out, fiberglassed down the back of the cockpit rim to make a solid 
backrest slightly padded with foam, and this has worked for me. I move my 
water to the front if I need neutral trim. How do you tell the trim of your 
boat now? Well, but the seat back where it was. The rigging couldn't have 
added that much weight, unless you added really heavy stuff. I though I was 
the only one doing that - other than fishers.

Carey, are you sure you are remembering this right? What you described would
likely work just the opposite way. More weight in the bow tend to make a
boat squirrelly and increases weatherhelm. More weight in the back tends to
make for stiffer tracking and less weatherhelm (or even a little lee helm if
overdone). 

There is a long discussion in our "Owners" manual on our website about when
and in what conditions bow or stern heavy trim is desirable, so those who
are interested can read that (it starts about 1/5 of the way into the
manual). I won't repeat myself here. 

To answer the original question, most would consider proper trim to be the
trim at which the boat is most efficient. For a kayak that would be when the
non-rockered area of the bottom (in the middle) is level (front to back)
when the kayak is floating at rest. A simple level placed on the hull in
front of the seat can probably tell you if the hull is level. When we
designed the original Mariner we did a lot of math (Simpson's rule springs
to mind) in order to figure out where the center of gravity of the paddler
plus boat should be for level trim. That allowed us to put the seating
position and cockpit in place before getting the boat wet. After that we
took a shortcut and just sat in the plug hull in the water with a
carpenter's level between our knees to determine the seating position and
cockpit placement. 

That said, for your Sea Lion you might find that while it slows the top
speed slightly (and possibly makes paddling at cruising speed not quite as
efficient) and makes for more pounding in head seas moving the seat further
back as you did (a stern heavy trim) will likely improve the handling of
your boat in sidewinds and following seas (less weatherhem and reduce
broaching). It will also make the kayak a little stiffer tracking (and
harder to turn up into a high wind when it is unladen). A side benefit will
be to make it easier to get in and out of the cockpit. Lay-back rolls may
not be as easy if the seatback is too close to the rear of the cockpit.

Most kayaks become bow heavy when loaded with gear. Think of the kayak like
a teeter-totter with the fulcum about in your crotch. Since your legs stick
out forward much more than your back does to the rear, gear going into the
front is further out the teeter-totter from the fulcrum so it takes less to
keep it level. With a full gear load it is very hard to put too much of the
weight in the stern. All water and the densest gear bags should all go in to
the stern.

    Carey, thank you so much, this was exactly what I was looking for. i am
a new paddler, got lessons and rentry skills but short on real experience.
When I took the seat out, I thought I would replace it, but decided I'd
rather go paddling than work on it, gee imagine that.

    Suddenly I an tracking great, all I did was maybe move the seat back 1/2
inch or so. I'll give some credit to continued work on my stroke, thanks to
Brent Reitz dvd, but the change is amazing.

    Next time I go out, I'll move the seat forward all the way, maybe 3-4
inches and see what happens then. Buy I have something to look for now.

    Thanks so much
