Well, to these tired old eyes, it looks like your "shark" has lost its "teeth", like maybe a depth charge took off part of the bow, including tube doors. Almost like your boat was almost filleted horizontally... Along with that, your "pectoral fins" (aka: dive planes) are gone... rather an odd looking Balao - but you still have your headlight!!! Or is that just a horribly water-distorted conn?... lol
