I installed an Icom 802 in my IP40. After much debate and concern over how to cut thru all the underfloor bulkheads with copper foil for a counterpoise I opted for the Kiss method radials. After an easy half hour installation of the half inch tubing from my tuner forward to the empty area over the galley I was ready.
I have easily contacted Hawaii over Pacific Seafarers net at a distance of 2500 miles and have on good days talked as far away as NZ and Aus. So far I do not regret this method at all-and it sure is easy compared to the alternative!
May the force be with you!
