I think the water spray issue is down to the unique design of the Bombards transom, but since its this shaped transom that gives it the performance advantage, we all work round the problem.

Short shaft engines have a 15" shaft as standard but on some of the bigger tiller engines the shaft length can creep up to 17". On a standard transom its not an issue but on the Bombard its can cause some splashing over the back. If you search on here you will see some incredibly well designed and manufactured raised transom solutions, but a simple block of wood works just as well.

My 25hp Yamaha has a 17" shaft



You can see its just a little too long for the transom (the cavitation plate should be level with the bottom of the transom).




Just a block of hardwood, not as good as some others, but does the job for now till I get time to make a better solution.

The bombard transom/ hull shape is a distinct 'U' infront of the leg -- this allows water to flow in from either side of the U onto the leg - and up the back of the transom into the boat.

Most SIBS have a very flat '_' infront of the leg - meaning water has to try and flow 'up' - which is by definition harder for it to do.

Joe, just thought to help with your decision making, I would suggest possibly considering that you may be wanting to change things in a season or two anyway depending on how your relationship develops with your interests and not viewing the purchase as a long term commitment, so the suggestions from others around compromise and selling on later are all very valid. Many change boats and change engines for various reasons all too frequently as well as dipping in and out of other type of boat/watercraft ownership.

Looks like the bombard aerotec is best air deck sib but not cheap!! I was considering a Honda Honwave with aluminium hard bottom. How do these perform and what is the set up time? Could one set this up and take down for the weekend every time? Only thing I see with these is most people trailer them. If I am to do this I may as will go for a light weight rib. Like a small rib eye???? Thoughts ..
