Judy,
Sorry if I sounded condescending. 'Twas not my intent. I was only going by your words, which came across to me as though you were a bit disengaged from the boat. I'm glad you are engaged, took the course and want a larger boat. When it comes to condescension, there are far worse offenders on here than anything I've said. Besides, sarcasm is more my thing.
As for your boat, I agree with Sailingdog that the Simrad will fit even with the folding wheel (also a great invention.) The unit also should not interfere with the throttle/gear shift if the wheel does not interfere with it already. Too bad there isn't a decent pic of the set up somewhere. I'll look for a pic of my old P-27's set up but it will take me a while.
