Arctic 22’

Hi I have a Arctic 22’ which has been gutted and a lot of work ahead.

It needs a new transom which I am using a 25mm + 12.mm marine ply which maybe over kill but better over than under.

The bit I am worried about is the transom height, the engineer has said from the keel to top of centre point can’t be any bigger than 24”? Is this right?

If so that means the top of the transom will only be 1” higher than the deck level...

Will this flood the boat when I come if the plain also where is the water line?

All advise or experience is welcome.
Thankyou in advance Click image for larger version

I would imagine that the 24" distance the engineer is talking about relates to the shaft length of the outboard. Do you have the outboard(s) already?

I'd Google Arctic 22 and look at the images. A number of them seem to have an inner bulkhead ahead of a transom well.

If you come off the plane quickly, you can get pooped by your own wake. You can turn the boat slightly so the wave comes under the quarter rather than directly over the transom.

Good luck with the rebuild. That's a significant project to take on.

Hi we are having a 250 Yamaha long leg

I ha e two options I think,

Keep the transom low and build a troph or bulkhead of some sort to stop water gushing in when boat slows

Or fit a outboard extension bracket to the transom, which would also allow a longer deck area?

Yes a big project also have a Arctic 28

I think I would go with the former. An extension bracket for a 250 would be a bit of an engineering challenge and you would probably end up increasing the size of the transom to cope with the cantilever loads.

You can get a 30" leg if your buying a new engine but maybe hard to find used

They was designed for a XL shaft (25” ) engine for single instillation or L shaft (20”) for twins
