Boat show was great! Got more convinced about my choice for Yam. Received some other eye-openers as well, resulting in my decision to save one more season so that I can order the boat I really want instead of buying second choice now for lack of funds...
Got convinced to go for a 4stroke instead of 2stroke engine. Other extra's I want installed are A-frame, Chart plotter, VHF and power trim/tilt (see other thread).
This spring I will make a test run in the 430 and 470. The 430 has the advantage that the seat in front of the jocky is removable, creating space for our two dive sets. That way I can do without the 40 cm extra and still keep plenty of seating space for two people.
It's still a lot of money, and I have to put the brakes on a bit as I want to do it right first time. Luckily I have you guys to sort me out on a number of things!
So, one more summer in the Zodiac...there are worse things I guess...
