Boat
The Etap 22i with a breakback trailer is about the largest boat that can be trailed, and launched, and is the most seaworthy in its class. The only slight downside is that its keel does not fully retract for drying out.
Where to launch
After some unpleasant experiences, I only use bigger concrete slipways, preferably with a place to moor up is useful, but only about 10% of the slipways listed are suitable for a large heavy boat, and looking at the slipway on Google Earth and Streetview is recommended.
