Hi and welcome to OSB, the Delta is a great boat and mine gave me a lot of fun. It was easy to tow, launch and handle. The only issue I had was the prop fell out once, which was a shire fluke. Caused a bit of concern until I beached it though. They are tough and good ski tow boats. Easy to maintain and reasonable for spares as they use a lot of common ones. Ray Wright built them after he left Albatross where he was an apprentice.
Quite a few people have them on this forum. BN
