Why not just ask CRT ???

As above but get a copy of the tidal charts (might be available from Cromwell but would ring first) and I would suggest reading the Hull ABP byelaws regarding pleasure craft after Gainsbourgh Bridge the Trent comes under there jurisdiction not CRTs and of course life jackets just in case have a safe trip

Just a quick note do Not put any pvc cable through polystyrene insulation as it will eat the pvc

2.5mm 3core flex clipped up every 150mm or run through trunking wont give any problems if fitted properly and back to a fused dis unit as a ring main) best through trunking if you have the space then you can add if needed later

For the cost of replacements and peace of mind why not just renew ?

They get my vote fast and good service

dont waste money get a good one then sell off later

Also compoae Pro acurate i belive and free

why not fit out and panel then inject the pu behind the panels if you carefully measure the volume behind each injection point it should not be a problem to the contractor to work out how much foams required or even try contacting Trident Foams Ltd they do pu systems and there tech people could advise you. ( I dont work or anything else for them )

GPS 3 free from google playstore work quite well !!

It wasnt written by CRT only published sent in from Beryl of the RBOA

If your talking sprayed on p.u.foam that will stick like s**t to a blanket on the grp itself with no air gap so to speak and the areas to be sprayed have to be clean and Dry as p.u form will react with moisture it would prob be cheaper to get an expert in to the job than diy

Head gasket gone!!?

Electric /hydraulic you need a bw/crt key
