On a modern welded steel boat, I should have said!

The swims on Loddon are fine enough for me, not the usual slab sided modern boat 

Swims like a fish with almost no wash and will reach 7mph with ease.

Very nice.

I know one boat when it was lengthened was cut at the front cabin bulkhead and the bit added to make a longer well. The front swim ended at the front of the cabin.

I just found the blog showing photos of the job which gives a good insight to the length and shape of modern swims

There was a fair bit of emphasis on good swim design being important in the 'Power in Reverse' topic. So what makes a swim a good or bad design. If I were designing my own 60' cruiser stern, how would I design the swim for the best performance.

 

I'd suggest starting off by doing a degree in naval architecture.

If that's a bit too much trouble then measure and copy one of Alan's middle Northwichs.

(Or are there 'better in astern' historics to copy?)
