Del Connelly used to operate two P22s out of Weymouth during the mid to late 90s. One with 115 hp John Deere and the other a standard 145 hp Mermaid. Cruising speed was a relaxed 18 - 20 knots with the 2 tonne boat weight making short work of waves and other boats wash but very comfortable for the divers.
Old Spice has 200 hp diesel giving 30 knots lightly loaded or 23/24 knots with 5 divers and all the coding equipment which is quite extensive, takes up lots of space and is heavy. Thankfully a P22 has a huge volume of space under the deck (which you can actually crawl down into) to store all this stuff. Do not underestimate the weight or space you will need for the coding equipment - liferaft, second batteries, life jackets, two anchors etc
Fuel use is lpm at 20 knots rising to 1.5 lpm at 30 knots.
