. . . and round is better than square.

I knew round was best!!

It was supposed to rain this AM, but the rain held off 'til PM . . .

I got some more pieces cut.

.
The extra 'stringers' are in line with the engine locations and notched for the splash well. I'm running short on the Coosa, but will see how much more is needed. I got a 1" thick sheet and a 1/2" thick sheet as well as a partial sheet left. We shall see how it goes . . .

Today I played trailer moving games . . . I want to see if I can get a decent balance point & manageable tongue weight.

The boat was about 6" off-center (to port) when we pulled the boat out of the water. So that was the first order of business. Once I got the boat lifted up in the air, I used my chain hoist to 'pull' the trailer to port . . . that was fun.

Then I 'very carefully' moved the trailer forward . . . about 20". So, I'll lower the boat and see what I have for tongue weight. As mentioned by several folks, I can always put some weight at the stern for transport to the re-power shop, then get rid of it once at the shop.

So the boat is 20" back of its normal position on the trailer. I just need to lower it and check the tongue weight. The trailer itself (no load from the boat) has a tongue weight of 350 lbs.

I just tuned in to this post. ....Nice project.
I haven't gone through all of the threads, so you probably explained this earlier:
This is going to move a lot of weight a long distance aft. What do you expect as far as floating waterline, planing, etc.

I was thinking about you the other day, good to 'see' you . .

Yes, Page 7 , post #130 . . .

I calculated the center of balance will move aft by 9 inches . . . the stern will be up by about 2 inches.

Total weight goes down by about 500 lbs.

I have no doubts that your weight calcs are spot on. ....previous experience with you on this still stings a bit.
