Hi Mick, like thousands of others I built the original kit, a simple build. The Current version has been improved so you should have no problems, The company is well regarded.
Re detail in the wells, some plans and drawings are sketchy or wrong about these. If you Google vosper crash tender and select images, you will find some pictures of the original boats. Download them to your PC / tablet and you will be able to enlarge them to see what you need. It worked for me.
Good luck.
Chas
