So what you are saying is the UK fishing sector should invest in building up the fleet while it has no income, and will have no guarantee of success in winning a licence in future, and when the time comes to bid, have higher overheads to do with repaying for this new fleet whereas the Spanish (for example) have already covered a substantial part of those debts.

No, what I am saying, and what you are having problems understanding, is that once the UK has control over our fishing grounds, our fishing fleet will see that expansion is worthwhile because the UK can decide who has access to those fishing grounds. It is not a matter of who will "win a license". The UK , as a (once again) sovereign nation, can decide to issue fishing licences for the benefit of UK fishermen.

My previous comment made clear that, in the short term, it might be better to sell 'short term' leases to other countries, while the UK builds up its fishing fleet once more.
