Well, it's that time of the year again, time to get the boats repaired and tuned for another season.
Those who followed my thread last summer know I torched the T180 ESC in my Red Spartan toward the end of the season. I decided to change out the hull, mostly because it is impossible to get the stink out of them when you fry the electrics, and partly because the deck was starting to separate from the hull and I couldn't convince myself it was worthwhile to spend any time repairing a scorched hull.
I made a few observations while stripping down the old hull and starting to prep the new hull, and since there have been inquiries from time to time on the differences between the two hulls I thought I'd post up a few pics.
NOTE: these are observations and quick measurements so no claim they are 100% representative. There may be minor differences that are not readily apparent.
Out with Old in with the New
First I looked at the rear of the hull, I can't see any difference in the transom or vee between the two versions. I have seen claims that the hull is 0.5 inch deeper but the measurements I took don't confirm this.
The transom is 10 cm deep from the deck seam to the tip of the V on both hulls, and the center of the stuffing tube is approx. 9.3 cm from the deck seam to center of tube.
The angle of the V is 49 - 50 degrees on both hulls.
The level is off bubble a bit in the photo, but my table is off bubble by the same amount

There is a bit of design difference on the rear of the deck
The top of the deck has a few changes, one is the change on the rear of the deck in the photo above, another is the obvious one everyone knows about which is the flat deck at the bow instead of the taper (sheer) of the old hull. A more pronounced cowl and deck edge ridges as shown in the photo below.
The center cowl and deck edge ridges are 2-3mm higher on the new hull.
The front of the hull is where the most noticeable changes are. The bow is a bit deeper (due to the flatter deck) and the rise is steeper. This should mean the New version Spartan should cut the waves a bit more rather than than lift up on them. Assuming of course the bow is in the water, not lifted out while planing on the rear pad.
The other thing I noticed is the planing strakes are different lengths. On the old hull the outside strake is 64cm long and the inside strake is 61.5cm long. On the new hull the lengths are; outside 65cm and inside 56.5cm long.
